The truth, I have learned, is that cool/cold areas are best suited for white wine production for a variety of reasons. Whites generally ripen earlier, and they are more forgiving, flexible and adaptable. It is easier to make a good wine from a wider range of maturity than reds. So cool regions that have shorter seasons may still produce acceptable and even excellent white wines. That is not so true of red wines. Red grapes need a long season of hot weather to mature to just the right sweetness.
