I’ve never tried using beats, but a local brewery in Southern California has. The Bruery in Orange County California http://www.thebruery.com/ brewed a Valentine theme, beet red beer. I have no idea how they used them but the beer was bright blood red and tasted a bit earthy yet good. All the girls were so into that beer, I’ve never seen so many women drinking beer.
Magic Hat Brewery in VT made their summer brew Wacko using red beet sugar I believe… made the beer PINK! I took a picture of it for some friends… let’s see if I can figure out how to post it here.
The color of the beets may make a difference. The red beets we grow stay a deep purple along with the juice even after being boiled or pickled. I may have to try a few in a beer too. What the hey. I’ll let you know how it workes out.
