Ice wine is an ultra-rich, super sweet dessert wine made from the intense liquid of naturally frozen grapes. The tradition of making ice wine is well-rooted in Austria and Germany (locally known as "eiswein");
The Legend of Ice Wine
Legend has it that ice wine was discovered by a German winemaker who was away from his vineyard during harvest (never a good idea), and when he returned all of his grapes had been frozen on the vine.
Undeterred he carried out the unorthodox harvest as usual and proceeded to press his frozen grapes for fermentation. The result, the first eiswein.
