Long line forms for Pliny the Younger IPA in Santa Rosa

SANTA ROSA, Calif. (KGO) -- Beer lovers are packed lined up for blocks outside the Russian River Brewing Company in Santa Rosa for a rare treat.

The limited release triple IPA Pliny the Younger makes its 14th annual debut today at the brewery. It's only available on draft at the brew pub for two weeks.

Brewmaster Vinnie Cilurzo is the mastermind behind the Triple IPA, a beer so tough to make they only serve it two weeks a year. He says warmed up just a bit, it's a symphony of citrus, floral and tropical notes.''
