THE FROZEN GRAPE: ICE WINE TASTING

THE FROZEN GRAPE: ICE WINE TASTING image

By Rose Murray Brown MW   Published in The Scotsman 3 June 2017

One of the hardest tasks in the wine world is the Ice Wine harvest.  In the dead of night in December or January, with temperatures well below -8 degrees C, teams of pickers work through the night in vineyards harvesting and pressing frozen berries.  The result is one of the most intense dessert wines in the world – but it is a labour of love.

“What people do not realise is that Ice Wine production always means a financial loss, certainly now in Europe”, says Eckart Waitz of Hans Lang estate in Germany’s Rheingau.  “In the past the magic low temperatures -8 C or below were more common and harvests earlier, now they are few and far between – many wineries don’t produce Ice wine anymore due to the risk of loosing all their grapes”, says Waitz.

In a good year Germany can make 120,000 bts of Eiswein and in Austria, Switzerland, Slovenia, Hungary, Moldova and Georgia tiny amounts are made when temperatures permit - but due to rising temperatures European Ice Wine is becoming scarce.

The one country in the world today with a regular supply is Canada (where it is labelled ‘Icewine’), consistently cold enough to produce 1-2 million half bottles annually, with 75% from Ontario.

There is also an interesting newcomer in the market, China.  Up in Liaoning province in northeast China near Russian and North Korean borders, conditions are similar to Ontario.  Here Canadian consultants advise Chinese wineries – with Vidal grape the most successful.

The hardy hybrid grape Vidal has been Canada’s popular choice since early 1970s when Canadian Icewine was first made.  Growers chose aromatic fruity grapes like Riesling or Gruner Veltliner, but some experiment with red varieties, with a demand for sweet red wines in Asia, like Cabernet Franc, Pinot Noir, Zweigelt and even Syrah. 

To make Ice Wine, healthy ripe grapes must have no ‘botrytis’ noble rot – and this is where it differs from Sauternes.  As grapes are left on the vine through winter, deer, wild boar and birds are attracted to the juicy sweet grapes (nets are essential) or disease, rain, wind or hail can devastate crops. 

Yet the hardest part is handpicking 2am - 6am, then pressing the frozen pellets of grapes, often as hard as marbles, before they thaw.  Natural freezing conditions concentrate the sugar, acidity and extract - and water in grapes is left behind as ice crystals in the press – resulting in tiny yielsd of intensely sweet juice which ferments very slowly.  

Tastewise, Ice Wine is intensely sweet – particularly Canadian ‘icewine’ which is picked at a higher sugar level – but it always has a freshness from enhanced acidity – and it is never cloying or too high in alcohol.  Many think Ice Wine should be enjoyed when vibrant, fresh and young.  Despite the high sweetness levels, Ice Wine can be a sommelier’s dream matching well alongside blue cheeses or desserts like mango sorbet and crème brulee.
