A Nice Side Effect of Cold Weather: Icewine!

Bill George has been up for two days picking Icewine grapes and is exhausted.

"Yeah, I'm pretty tired," the Chair of the Grape Growers of Ontario admits from his Niagara grape farm during a phone interview. "But you really go to town when the temperature is right."

And boy, is it ever right.

Southern Ontario is nearing the end of a week-long cold stretch that has been feeling all the more frigid, as it snapped the province out of a prolonged January thaw with at least one day with record-breaking warmth.

"In Niagara, there were 17 days in a row where there was thawing temperatures," says David Phillips, the senior climatologist for Environment Canada, noting one day reached nearly 18℃ degrees in St. Catharines. "It was downright balmy."

But all that came to a screeching halt last Sunday, when Arctic air blasted out the warmth, plummeting temperatures to about -10℃ and blowing such ferocious winds Niagara's Annual Icewine Festival was forced to shut down its Icewine Village -- when just the day before visitors were enjoying a very civilized +7℃.

"It's almost a black and white situation," says Phillips, noting that while this cold snap is not the coldest on record, it is 10 or 11 degrees colder than normal. "They [grape growers] must be gleeful. There's a nice, beautiful window here ...that's almost tailor-made for icewine production."

Indeed it is. This frozen week has given crews enough time to get in their entire crop before the weather warms up again on Monday.

"Most guys said they needed 2-3 nights to bring in their grapes -- the really big guys needed three to four," said George, who runs a 140 acre family farm growing grapes for wine companies like Constellation Brands.

George says ideal temperatures to pick Icewine are around -11℃ or -12℃, which usually means the harvest happens sometime between Christmas and New Year's Day. While some crews have managed to get out into the vineyards here and there, for the most part grape growers have been in a holding pattern, waiting for Mother Nature to give them the green light to pick.

In order for producers to legally call their product "Icewine" (yes, capitalized and all one word -- it's trademarked in Canada) a series of very strict criteria must be upheld, including picking grapes naturally frozen on the vine (no freezers allowed) and picking those grapes at a minimum of -8℃. Often that means picking in the dead of night, as the sun's warming rays can thaw frozen grapes -- even in sub-zero temperatures.

Another bonus for Icewine production, says Phillips, is that by the time the week is through, we will have had seven days without any thawing temperatures.

"There will be no grapes that will go unfrozen," assures Phillips. "They could not have ordered better weather."

Back in Niagara with all the vines picked clean, George says the three-week delay didn't hurt the grapes or the vines and he's happy with the quality of the fruit.

"Everything to me is in good shape," he says. "Now we're pressing and I can relax a little."
