I am a little bit behind, so most likely everyone has processed/recycled this beer already. If not, then you should go and drink one. The current trend in beers is to brew obscure and forgotten styles: gose, grisette, gratzer, etc. While the kellerbier/zwickelbier is not obscure it does by far have the coolest name. The United Front collaboration beer label states "unfiltered braun beer". When you say unfiltered lager, you might be referring to a kellerbier. This translates from the German to read "cellar beer", or beer served directly from the lagering cellar. Braun means that is the brown, as there are pale (helles) or amber (Marzen) versions of kellerbier. So what did the beer prick think about the front?
United Front = 6/10
The aroma was a little subdued with hints of mint and lettuce; so a well lagered aroma. Dissolved yeast provided a suitable mild to medium mouthfeel with a slight slickness of diacetyl. Diacetyl was low which is suitable for this style. As with any beer that declares the use of Vienna style malts, the dominate flavours were lightly toasted, grainy with small amounts of earth. Rounding out the palate were dark fruits, prunes and a little green apple. Green apple is not unheard of for an unfiltered lager. These tastes did not linger and provided a clean finish.
Alcohol Content 0 5.8%
Appearance +1 (simple label are relatively good description of flavour)
Glassware: A lager glass, common pint or a dimpled mug
Food Pairings: Roasted light meats, pork, burgers, lamb. Could also work with grilled vegetables or kabobs.
Cellar: The dissolved yeast might further change the flavour, but the simple malts and low hop presence, cellaring might not be suitable.
SRM 16.5. On the label the EBC (European Brewing Convention) of 32.5 was stated. EBC= 1.97*SRM. This above the range for a Vienna lager (9-15), in the range for an altbier (11-17) and low end for a Munich Dunkel (14-28).
IBU 35. This IBU range makes it hoppier than most German lagers, except for the altbier which has a very wide range (25-50).
