Last night when I was out and about San Francisco, I came across the cutest little dive bar, The Black Horse Pub. Virtually a hole in the wall, this eclectic "deli" has a bathtub behind the bar filled with various European brews. When I asked the delightful bartender for the lightest bottled beer, he pulled out a beer I had never heard of before: a French lager called Kasteel Cru.

This interesting and refreshing beer is made with champagne yeast fermentation. While all beer has carbonation, Kasteel Cru has the fizzy effervescence normally found in sparkling wine. With its frothy head, and clean, crisp flavor, the golden-colored beer is incredibly drinkable. When sipped, it tickles the throat.

Kasteel Cru is best enjoyed in a special pilsner glass that resembles a a stemless champagne flute. If you're a beer aficionado, I highly recommend seeking out this bubbly beer. Has anyone else tried it?
