On an overcast February afternoon, winemaker Bennett Price walked away from a barrel of wine he was readying to bottle and headed outside, to a fence near his DeBeque Canyon Winery where clusters of very dry grapes were shifting nervously in the breeze.
“These are Pinot Noir,” he said, reaching under the bird-proof netting drawn over the vines. “They were pretty good grapes, too, but they came on real early last spring, too early really to do anything with.”
On the third consecutive day of 60-degree plus highs, in what’s suddenly behaving as if it were the northern extension of the Colorado Banana Belt, one can be forgiven if the weather has you thinking more of mid-spring rather than mid-winter. While the sides of nearby mountains still wear thick blankets of snow, there hasn’t been any snow, or any moisture of any kind, in the lower valleys for several weeks.
Instead, here at 4,200 feet, plenty high enough for winter to return for another month or two, birds are building nests, golfers are swinging away and winter-dormant lawns are starting to green.
“I think we’re going to have an early bud break,” Price said. The unseasonal temperatures “warm up the soil too much and that stimulates the roots to start pushing.”
The temperatures, while warmer than normal – unless this is the new normal – still haven’t been consistently high enough to break the vines’ winter dormancy. It takes 50 degrees to see the return of spring, said state viticulturist Horst Caspari.
“And that’s on a 24-hour cycle, not just a quick jump up and then back to below freezing,” he said. “We’re still getting enough diurnal variation that nothing’s broken yet.”
Yet Bennet Price isn’t convinced after hearing a weather forecast calling for cooler temperatures followed by more warm days.
“We were up to 60-something yesterday and our low was 46 or something like that and today it’s back up there again,” he said. If the vines do respond to the warmth, “hopefully we won’t go back down to the low 20s or teens because you can start damaging the canes and trunks because the sap’s coming up.”
Tree-fruit growers are extremely wary of such mid-February warm spells because their trees are close enough to bud break that prolonged mild weather can bring early and unwanted development. Climate change hasn’t yet brought Western Colorado to where a heavy spring frost is out of the question.
Grapes, however, come on several weeks later than cherries, peaches and apples, which gives a bit of leeway and enough time for the weather to back to cold.
“But he’s right, the ground is being warmed up,” agreed grape grower Neil Guard at Avant Winery on East Orchard Mesa. “And look, it’s dry, there’s no snow at all. Which means if it stays warm, the vines are going to need water and we can’t get any irrigation water until April 1.”
Should the vines suffer freeze injuries, they then are susceptible to a bacterial infection called crown gall, which can eventually kill the vine.
Crown gall, caused by a bacterium that lives in the soil, also can result from mechanical injuries caused by normal vineyard maintenance such as pruning, grafting and training vines.
“I’m working in some vineyards and I have to go through and mark the vines with crown gall so they don’t prune that vine,” Price said. “You don’t want to prune that vine because if you prune it and then go to the next vine, you’re going to pass that bacterium to the next vine.”
He said the only way to treat crown gall is to pull and burn the vine and replant.
“It’s just another thing to think about if you’re planning on owning a vineyard,” Guard said, with a laugh.

2016 may go down as the year Nature caught up with the wine business.
Fires, freezes and bouts of hail were among the changes brought to the world’s wine industry and the people who work there.
Foremost, of course, was Chile, which suffered what Chilean President Michelle Bachelet called “the greatest forest disaster in our history.”
More than 135 wildfires burned an estimated 1 million acres (404,685 hectares) of land, nearly four times the size of New York City, including more than 100 vineyards in the wine-producing region of Maule in Chile’s Central Valley, that country’s top wine-producing region.
Chile is the world’s fifth-largest wine-producing country and in 2015 exported to the U.S. alone more than $1.9 million worth of wine, according to the USDA’s Foreign Agricultural Service.
While forest fires are accepted part of Chile’s hot, dry summers, this year has been especially difficult, said NPR’s Phillip Reeves.
“These (fires) have taken on disastrous proportions, thanks to prolonged drought, strong winds and unusually hot weather,” Reeves said.
The wildfires destroyed towns, forests, plantations and vineyards and killed at least 11 people in Central and Southern Chile, several news reported.
Firefighters in Maule reported temperatures reaching over 100-degrees C (212 F), leaving homes without power after their cables melted. Three firefighters lost their lives while battling the flames.
Sergio Amigo Quevedo, winemaker at Cancha Alegre in the Maule region, lost six hectares of old vines to the fires.
“It’s hard to believe that vines you’ve taken care of with such love and sacrifice are lost along with part of the viticultural patrimony of Chile, because of a voracious fire caused by careless men,” he told Decanter.com.
Diego Morales of Bisogno Wines lost 25 hectares of 150-year-old País vines, having tried to fight the fire with his family.
Carlos Gálvez of Bisogno Wines said in an interview with The Washington Post, that unless his vines recover next season, he will lose half its wine production.The winery’s blog posted a video showing a hellish landscape of fire-destroyed vines.
“The fires destroyed our vines but not our dreams,” Gálvez said. “This is a low-income region, and many live off the vineyards. There are some who have lost everything.”
The fires are thought to have been started by arson.
There also were fires in South Africa, where up to 40 percent of the 300-year old Vergelen wine estate was destroyed; in California’s Lake County where an arson-caused fire razed 1,600 heroes (about 4,000 acres) including the Tuscan Village winery and community complex; and in France’s Languedoc-Rousillon more than 1,200 hectares were burned.
It was reported wild boars caught on fire and then ran, spreading the flames through the vineyards and forests.
The fires came only a few months after the Languedoc area received a deluge of hailstoms that damaged up to 60 percent of the 2016 grape crop, said Decanter Magazine.
Similarly, Chablis suffered two bouts of hail and an unseasonal frost reduced the forecast size of the harvest in Burgundy, Loire and Champagne.
One of the terms tossed about during last week’s discussion of the discovery of phylloxera in Colorado vineyards was “symptomless carrier.” Which means (in this case) a grape vine may have phylloxera (which is the tiny bug that kills vines by attacking their roots) but shows no sign of the infestation.
I know, that’s not the preferred medical definition but give it up, these guys are grape growers, not doctors. Except, that is, for one or two, who offered this definition – A symptom is something only you know is there. A sign is something other people can notice.
Whether you use symptom or sign, the concern is the same: you might have an aphid-infested grape vine and not know it until it and its neighbors start to wither.
And with phylloxera, that physical manifestation is just the tip of the aphid iceberg because by then the bugs have spread.
First the worst news: “The rule of thumb is, once you find phylloxera, the vineyard is doomed,” intoned Bob Hammon, entomologist at the CSU Extension Service, during the packed-house phylloxera seminar Monday at the 2017 VinCo Conference.
And as of this writing there have been four vineyards in the Grand Valley positively identified to be phylloxera positive. Only one has been publicized.
“There’s no doubt in my mind it’s far more widespread,” Hammon said.
The bug will kill (most of) your vines but not all at once, Hammon and other experts warned.
It may take the phylloxera aphid a decade to move through your vines, which gives the grower time to save his livelihood, if not those specific vines.
While there are exceptions to every case, phylloxera kills vinifera vines, not the native American grapes that developed alongside the bug and have some resistance.
There are some sites in Europe (and here), which first noticed phylloxera in the 1860s after American grapevine cuttings spread it there, that haven’t been affected in the 150 or so years the rest of that continent has been tearing up and replanting vineyards.
Getting rid of own-rooted vines, especially vinifera vines, and using grafted rootstock is one and probably the surest way to combat phylloxera.
It’s expensive, adding about $2.50 to the cost of a vine. Plus, you could leave the vineyard fallow for a year and then wait another 3 years for a crop.
And you still must be careful about not spreading the bug around by carrying infected soil on your boots or tractors or other machines.
Also, grafted rootstock need protection against the harsh winters we get in Western Colorado.
Those aphid-resistant American grapes? Most of them don’t make good wines, or at least not wines demanded by most consumers.
Using vinifera vines grafted to resistant rootstock allows growers to produce the grapes winemakers want.
“No region has even succeeded in keeping it from spreading,” said Nancy Janes of Whitewater Hill Vineyards and Winery. “You can slow it down a lot but nobody has succeeded in stopping it.”
It comes down to managing the bug once it appears.
If you’re a big grower like Bruce Talbott, whose company manages upwards of 40 vineyards across the valley and consults on another 20 or so, your decision is rooted in economics.
If a phylloxera is found in their vineyards, “our response probably will be we assume everything we farm has got phylloxera and we will spray it with Movento,” a systemic insecticide against sucking pests, Talbott told the VinCo seminar.
“If it costs $100 an acres, it costs us $100 an acre,” he said. “That’s a lot cheaper than the other things.”
If you’re smaller, it’s still economics. Is it cheaper to pull your vines, wait and then re-plant or do you go into another crop, like peaches?
“Unless we get Napa-like prices, grapes will never replace peaches as a cash crop,” offered Talbott. But growing grapes allows him the latitude of keeping his Mexico-based crews working for six months or more.
For small-acreage growers, “the better approach is if it’s in here now, I better work at replacing a third or quarter of my vineyard,” said state viticulturist Horst Caspari of the CSU Research Center. “That way I stay in the production and not go (without a crop) for two or three years.”
Sometimes, when the days are short and cold and summer is but a memory, I spend winter hours looking for wines that remind me of warmer times and sunnier climes.
I recently found two wines that took me back to a few days late last spring spent wandering the vineyards of the Veneto and Tuscany. Both wines are from Tommasi Family Estates, the 115-year old company now in its fourth generation of winemakers with its base in the heart of the Valpolicella Classico region of the Veneto.
Tommassi, named after founder Giacomo Tommasi, has vineyards in four regions: Veneto; Olto Pavese in Lombardy; Tuscany (Montalcino and Maremma); and Manduria, in Puglia. From each of these regions come wines as distinct and unique as the vineyards where they grow.
The event was a simple gathering of good friends for a holiday dinner and talk, a simple yet warm get-together so remindful of previous dinners spent at the homes of winemakers around the world, where formality drops away and the talk turns to the state of wine in general along with family, current politics and wherever the mood take us.
Tommasi Ripasso DOC Valpolicella Classico Superiore 2013 – As we all know, the story of Ripasso wines is intertwined with the story of Valpolicella and Amarone. Briefly, a Ripasso is made by refermenting Valpolicella on the skins left after Amarone is fermented. The result is a wine that’s darker and more intense in flavor than the original Valpolicella and goes well with winter-style comfort foods or even a grilled steak in the summer.
You could call a Ripasso a “baby Amarone” because the former uses the same grape varieties that go in Amarone (Corvina, Rondinella and, in this case, Corvinone) and you get some of the same aromas: dark cherries, dried cranberries, heather, and spice.
But it’s less-expensive, generally in the $20-25 range.
We had this wine with grilled chicken, fresh green salad and homemade bread. You would have thought it was July until the wind howled and snow blew past the windows.
Tommasi Poggio al Tufo Rompicollo Toscana IGT 2013 – We opened this wine for the cheese course and while there’s nothing overwhelming about the wine, it brought a smile to everyone’s face. Maybe that’s the key – it’s not overwhelming, it just goes well with food and good company.
Plus, it’s one of those rare finds that is affordable, very tasty and pairs well most lighter meats, pastas and cheeses. And, if you’re into this sort of thing, you can close your eyes, take a sip and imagine you’re in the Tommasi vineyard in the historic Etruscan area of sunny Maremma in southwestern Tuscany, midway between the Tyrhennian Sea and Rome.
The wine is a blend (60 percent Sangiovese, 40 percent Cabernet Sauvignon) from a sun-drenched vineyard on volcanic soil. The word “tufo” is Italian for the volcanic tuff found in the Maremma and a common building stone for Rome. The wine has bright flavors of dried Montmorency cherries, currants and hints of sage and white pepper. $12-$15.
Both wines are imported by Vintus Wines, Pleasantville, N.Y.
VinCo, the annual Colorado wine-industry tradeshow and conference sponsored by the Colorado Association for Viticulture and Enology (CAVE), kicks off Monday (Jan. 16) and of certain interest will be the discovery of Phylloxera in commercial vineyards in Colorado.
Phylloxera, as any good student of wine should know, is a microscopic aphid which, depending on the strain, feeds on the sap in grape vine leaves or roots. The aphid causes fungal infections as well as galls (see photo taken by researchers at the University of Wisconsin-Madison) to grow around the feeding site, blocking the flow of nutrients to the rest of the vine and potentially killing the vine.
Certain varieties of grapes, particularly the much-preferred European (Vitis vinifera) grapes, are extremely susceptive to Phylloxera while some native American grapes, which developed alongside Phylloxera, are tolerant or resistant. In the 1850s Phylloxera inadvertently was transmitted via infected grape vines to Europe and by the late 1860s the louse was making havoc of the European vineyards, especially in France.
It’s estimated that nearly three-quarters or more of Europe’s vineyards were stung by Phylloxera. Not until European growers learned to graft European vines to aphid-resistant American rootstock did Europe’s wine industry recover.
Phylloxera has been seen in wild Colorado grapes for years but not until in 2015 was it found in a commercial vineyard on the Front Range and then last November on the Western Slope.
“I’ve been concerned about it for quite some time,” said Bob Hammon, an extension agent with the Colorado State University Extension in Grand Junction. He said records of Phylloxera in Colorado go back at least a decade or more. “I figured it was going to catch up with us eventually.”
Because it was thought Colorado vineyards were Phylloxera free, grapevines here mostly are own-rooted, not grafted roots. The benefit is that should the vines freeze to the ground (which happened here in 2009, 2013 and 2014), the new growth will be true to the variety planted.
With a grafted root, if the upper part freezes, you don’t know what will sprout below the graft.
Grafting popular European grape varieties to American rootstock doesn’t get rid of the aphid but you get the grapes you want. Because Phylloxera is spread through the soil, one way to prevent spreading the aphid when importing vines is to hand-dip each vine in hot (125-degrees or so) water.
John Behr and Nancy Janes of Whitewater Hill Vineyards and Winery started hand-dipping several years ago when they began importing rootstock from Phylloxera areas in the eastern U.S.
“Back there, hand-dipping is an accepted practice,” Nancy Janes said. “When we’re getting grapes from known Phylloxera areas, we do it as standard practice.”
That includes parts of both California and Oregon, popular rootstock sources for Colorado’s grape growers.
Although other wine-producing areas have spent many years and even more dollars studying Phylloxera, research in using grafted rootstock is sparse in Colorado, said state viticulturist Horst Caspari.
“We haven’t had that necessity,” he said. “But the rest of the world uses grafted rootstock and we can build on that.”
Because Phylloxera kills slowly, Caspari said grape growers have time to adapt to new methods of vine management.
One current option calls for uprooting and burning infected vines and the field left fallow for a year before replanting grafted rootstock. But grapes need three years to produce a crop and that’s four years in all, “a long time to be without a paycheck,” noted Hammon.
Also, since Phylloxera can be spread on dirt-covered farm equipment, vehicles, and even vineyard clippings, management becomes more complex, said Hammon.
“We have to extra diligent about sanitation, paying attention to how you move equipment and people from field to field, it’s very challenging,” he said.
And wine-making already has its share of challenges, Nancy Janes noted.
“It’s absolutely heart-breaking knowing that it’s here,” she said.
The VinCo panel discussion on Phylloxera will be 1 p.m. to 5 p.m. Monday at Two Rivers Convention Center. Information at the CAVE website.
With the New Year upon us and winter settling in, it’s nice to find some sunshine in a bottle. A brief flurry through some unopened boxes revealed these three bright notes for what may be a dreary political season.
2010 Arnaldo-Caprai Collepiano Montefalco Sagrantino DOCG – On those austere winter nights when temperatures plummet and the grill is working overtime providing steaks for a hungry post-ski holiday crowd, nothing says warmth like the full-bodied warmth of a Montefalco Sagrantino. The history of Sagrantino the grape goes back at least 400 history in the Montefalco region of Umbria and probably more, if some of the oldest texts are correct about vineyards existing in the area prior to 1100.
The Montefalco area was designated DOCG (denominazione di origine controllata e garantita) in 1992. The DOCG area includes the commune (municipality) of Montefalco along with parts of Bevagna, Guild Cattaneo, Castle Ritaldi and Giano dell’Umbria.
You don’t need to be a historian to enjoy this ruby-dark wine from Arnaldo-Caprai, with its velvety mouthfeel, smooth plum and blackberry notes with hints of spice (a seasonal mix of clove and nutmeg). It’s a wine made for red meat and hearty meals, with assertive, chewy tannins and even six years after release still capable of further aging. $54, sample.
2013 Kit’s Killer Cab – Think of Clif Bars and the image most people get is of the high-energy bars found in backpacks, briefcases and lunchboxes around the world.
Today, though, there’s a whole ‘nother Clif world, thanks to the efforts of Clif Bar founders Gary Erickson and his wife Kit Crawford, also happen to be the CEOs behind Clif Family Winery, the duo’s high-energy Napa Valley winery.
Most Napa winemakers rated the 2013 vintage as “ideal” and this Cabernet Sauvignon sourced from the family’s Croquet and Cold Springs vineyards on Howell Mountain reflect those near-perfect growing conditions. Lush and smooth, with dark fruit balanced by even tannins and a bright future. Drink it now or hold it for a few years. $75, sample.
2015 Pessimist – This affordable red blend (Syrah, Petite Sirah, Zinfandel, Tannat, Grenache) is a second label from the much-respected Daou Vineyards of Paso Robles. The Daou team of winemakers makes this very much a first-tier wine, with dark berries, vanilla bean and black pepper notes tucked around smooth, seductive tannins. Your friends will guess you spent much more. $20, purchased.
If the recent political season wasn’t sufficient impetus to get you thinking about improving your drinking choices in the coming year, maybe a few New Year’s resolutions will do the job.
Even if you’re not someone prone to make resolutions, already knowing how stark end-of-the-year choices can seem when viewed with a few month’s distance, there are several painless things you can do to ease into what so far certainly promises to an interesting New Year.
Get to know your local wine industry – Yes, I know this sounds obvious if you live in the wine-country of the Grand Valley and North Fork Valley, but after several recent visits to local wineries (and a boatload of comments heard during the Colorado Mountain Winefest), I’ve noticed there are many people from both sides of the Continental Divide who admit to have never (never!) visited any of the wineries.
Yet many of these same people boasted about visiting Napa or Sonoma and paying (paying!) to taste whatever was pushed across the tasting room counter.
Pay-to-taste hasn’t yet taken over the Colorado wine industry. Most places gladly offer free samples although there are some wineries who charge for their premium or reserve wines. But they usually credit you if you actually buy a bottle or two.
Branch out – Meaning, know what you’re drinking. Instead of absently blurting, “I want a red wine,” ask for a Pinot Noir or a Cabernet Sauvignon or a Malbec or something else, red or white, but ask for it by name. You can even practice saying the name before entering the winery.
Most wineries you visit are pouring several different reds and whites, and engaging in a few minutes of conversation will not only improve your knowledge but your experience, as well.
Seek out cold-hardy varietals – Some growers will tell you the future of Colorado wines lies in cold-hardy varietals, at least until climate change reaches the point the Grand Valley consistently produces the traditional European varieties like Cab Sauv or Merlot.
Some growers already are vinifying cold-hardy varietals such as Marechal Foch, Cabernet Franc, Aromella, St. Vincent’s, the list goes on. Grape grower Kaibab Savage is growing nine cold-hardy varieties east of Palisade, trying to see what produces and what sells.
Join a wine club – I wouldn’t have said this a few years ago because (IMHO) choices were limited and the wines often over-priced and under-valued. Besides, how hard is it to drive 10 minutes to the local winery?
However, I’ve changed my mind. The number of clubs has increased, which may be an indication of their popularity. Chosen wisely, the right wine club offers convenience (home delivery on a regular basis), variety you might not try if left to yourself and, as I saw this past year, in most cases fair pricing. Not always the best, but fair, especially considering you’ll often get a higher level of wine than what’s expected.
There are many other possible suggestions but this will be enough to add a little viniferous sparkle to your New Year. Heaven knows, we may need it.
