The seminars will be "Cheese And Ice Wine, An Unexpected Delight," "The Romance of Chocolate and Ice Wine" and "The difference a D makes when selecting an Ice Wine," according to the event's Facebook page.

Vintners that have joined Casa Larga at the event include Leonard Oakes Estate Winery, Merritt Estate Winery, Hunt Country Vineyards, Sheldrake Point Vineyard, Schulze Vineyards and Winery, Fulkerson Winery, Knapp Winery and Mazza Chautauqua Cellars.

"We want to put New York state on the map for ice wine,” Andrea Colaruotolo O'Neill, director of operations, said in a news release. "... It is not often that we can produce products where our weather actually gives us an advantage over areas like California."

Ice wine comes from grapes left on the vine months after the regular harvest has been collected and allowed to freeze. They are removed from the vine and pressed while still frozen. The result is a smaller amount of concentrated wine with a sweet, intense flavor.

Unusually warm or cold weather before harvest will damage the grape crop, and hungry animals pose another risk.
