My current number one is Palmetto Brewing Company's (Charleston, SC) pale ale. It is lightly hoppy, with a smooth flavor and very good, crisp after taste. Really first class. Unfortunately, their Lager is, so far, really horrific, almost sour in flavor. I'm going to write them to find out if the lager has been handled improperly or something since it's quite odd for a company to have such dispartity among their products especially if they're both made in house.

In California, I made Red Nectar my number one. Different that a Pale Ale, it was more of a fine Scottish Ale, with a less sweet after taste. The brewery was near Humbolt State University initially, I had the chance to visit the Brew Pub and restaurant; but is now located in Paso Robles, purchased by a beer enthusiast and moved completely. The beer changed somewhat, but is still very good.

I seldom drink imported beer these days, beer doesn't get better with age, and most imports take too long to get to the consumer. Why waste time with them when so many excellent beers are being brewed in America these days.
