Pic(k) of the Week: Stainless steel row

In a stainless steel row, conical-bottomed uni-tanks hold beer in various stages of fermentation, in the cellars of Legend Brewing Company, in Richmond, Virginia.

Developed in the early 20th century, the unitank is nearly ubiquitous in today's micro-breweries. The tank can hold fermenting beer in a sanitary, semi-sealed environment, as well as beer that is maturing and beer that is lagering at temperatures near 0 °C. The bottom 60° angled cone can collect yeast that settles from solution during and after fermentation. Those all-in-one features gave rise to the name unitank.

The photo was taken at Legend on 27 February 2011, during festivities marking the brewery's 17th anniversary.
