Quite by accident, I left a bottle of Trimbach 2001 Riesling in the freezer a bit too long to chill, and came up with a strange, accidental eiswein. However, the flavor was not bad, and the result might actually be useful for a summer picnic. Just for laughs, here is the tasting note:
Appearance: Shard-like, slushy, opaque.
Nose: Quite closed, faintest hint of lilly of the valley.
Palate: Essence of tart Granny Smith green apple, lime popsicle, bracing acidity. Wonderfully concentrated flavor ;.>
Overall: Despite this very unusual experiment, this is a very pleasing wine and will repeat this process again.
