The ideology of “drinking local” is totally doable if happen to live in California, but what if you live somewhere cooler? There are many places that were long considered a wine “dead zone” (The Midwest, Canada, Switzerland, etc) because winters were so cold that they would kill European wine varieties (Temps drifting down to -18 ºF / -28 ºC). This actually happened in Michigan in 1994 when two freezes took out an entire vintage and killed all the European vines (save for Cabernet Franc and Riesling).
