What if the harvest doesn't come? Niagara icewine-making is 'an extreme sport'

Jamie Slingerland knew it was coming. He just didn't know when.

At 2 a.m. Friday morning, it finally hit the magical8 C, the bare minimum needed to harvest icewinein Ontario. With a small window, Slingerland'sstandby crew swung into action, harvesting as much of their kilometre-long crop as they could.

The mild winter weather kept Slingerlandwaiting. He looks after the vineyards for Pillitteri EstatesWinery in Niagara-on-the-Lake. In his 30 years making icewine, he hasnever missed a harvest.

He can't.

"There is so much at stake," he said."We can make a million bottles of ice wine out of this field if the conditions were perfect. A million bottles is a lot of bottles of ice wine but if the conditions aren't perfect and we get half of that, it's a severe hit."

Slingerlandfigures, due to theweather, he's lost30 per cent of hiscrop. And he still has more to go. He's hoping for a coldSaturday night.

'Like a big anvil over your head'

It's been a tricky winter for icewinein Niagara. It hasn't been cold enough for long enough. There was acold snap lastNovember andsome wineries decided to harvest then. But many grapes just weren't ready.

Harbour Estates Winery took the year off from icewine they've been making it for almost two decades. Owner Fraser Mowat looked at his grapes in the fall and found they weren't in good enough condition. He's glad heskipped out.

"It's a difficult year to harvest," he said. "[In] 2001, we had only three nights that we could get icewine off. Every other year since then, until now, we've had lots of nights to be able to get icewine off."

David Sheppard agrees. He'snow the winemaker at Flat Rock Cellars, butmade icewinefor more than 35 years at other local wineries. He's thrilled he doesn't have to do it anymore.

"I feel badly for the guys that are, because this would be one of the tougher years," he said.

Sheppard said waiting for the harvest was the worst part.It's like beingon call all winter long."It's one of those things that's just looming like a big anvil over your head hanging by a rope."

'You gotta believe'

The icewineharvest gets harder the longer you wait. Grapes dehydrate and dry out. And thenthere's the birds.

Slingerlandestimates birds ruin one to two per cent of the grapes eachday from December on. Pillitteri Estates has a full-time employee who drives around the vineyard, making noise and firing flares to scarebirds away.

Sue-Ann Staff is still waiting on the perfect night. She runs the Sue-AnnStaff Estate Winery in Jordan, Ont. It has asmaller bounty there are 13-and-a-half rows of grapes. She can harvest themin a single night.

"To me, it's an extreme sport," she said. "You have to be willing to go the distance and live a little bit on the edge or else, don't bother."

She has made order commitments in other parts of the world and doesn't have enough stock from last year to fill them. Climate changehasprevented wineriesin Europe from makingicewineso the pressure is on forNiagara to fill the gap.

"Those people are counting on this to happen as am I. That's why it has to happen," she said. "You gotta believe."

Adapting to climate change

Icewinemakers in Niagara are well aware of the threatclimate change poses to their livelihood. Slingerlandthinks it will mean smaller windows for him to harvest.

So he's started to adapt.

He used to have people handpicking. But he hasswitched to machines.They can get it done faster if the cold doesn't last. He has also put up wind machines. They can heat the vineyard by three or four degrees if it gets too cold.

"It's a very high risk for us obviously but then the reward is worth it. It's a very sought after product," he said.

"There's a million Chardonnays in the world but there's such a small quantity of ice wine in the world and so few people produce it."
