This wonderful Oktoberfest brew shows lots of grain in the aroma with some faint spice and light citrus. Sweet, malty flavors and plenty of grain are complemented by some light spiciness. The Craft Beer Geek sez: Weihenstephaner has a solid claim to being the world’s oldest brewery, with continuous operations since 1040, almost 900 years before the first Oktoberfest. While it clocks in at almost 6% ABV, this fresh, crisp festbier is easy drinking, refreshing, and clean as a whistle.
