Buzz: Chester County? I thought they only grew mushrooms there.
Marnie: See, that's a perfect example of the preconceptions that Pennsylvania wine has struggled to overcome. In any wine region, there's always a long learning curve as vintners discover which grapes perform best in which regions, and adjust their winemaking practices to local conditions. Up-and-coming regions are often judged most harshly on their home turf, since the local community gets exposed to early trial-and-error experiments and less ambitious wines.
This is hardly fair. Every region on Earth makes more modest wine than fine wine, but people don't write off California based on one taste of Thunderbird or Barefoot.
Buzz: But isn't it too cold here to make good wine? I thought California had the perfect wine-country climate.
Marnie: Not really. Our summers are actually quite warm, and it's the grape-growing season that's important.
Our main challenge is that we get more clouds, rain and humidity here, which increases problems with rot. But it's important to remember that California is hardly the "norm"; it ranks among the hottest of the world's fine-wine regions.
Southeastern Pennsylvania is much closer in climate to places like France and Italy, which have proven that such conditions can produce world-class wines.
This is one reason why our best wines display a European flavor profile - one that skews more toward food-flattering, earthy-herbal flavors and less toward the dessert-like jamminess found in hot, arid places like California.
Buzz: Well, as long as it doesn't taste like 3rd and Luzerne, I'm down with it.
