00:00Your favorite lakeside wine might owe its flavor to summer heat, saved up in the water.
00:05Along the Great Lakes and between New York's Finger Lakes, vineyards get a boost from a natural heat bank.
00:12Water warms and cools much more slowly than land, so when autumn chills arrive,
00:16the lakes are still releasing warmth stored during summer.
00:20That helps keep nearby vineyards a lot milder, delaying the first frost and giving grapes extra time to ripen and
00:26develop flavor.
00:26The hillsides help too. Cold, dense air drains downhill, making sloping vineyards a little less vulnerable to frost
00:34than low spots where that colder air collects.
00:36So when you see those vines overlooking the water, you're looking at more than a beautiful view.
00:40That lake helps buy time before harvest deep into the fall.
