We recently tapped the Lone Pint Gentlemen's Relish, (on CO2), an English Brown Ale from a great Texas craft brewery! In the past, we've served this beer both on Nitro and on CO2, and the staff unanimously agreed that we liked the CO2 version better.
English Brown Ales are known for their nutty/toasty maltiness with hints of chocolate, and this beer is no exception. A commercial example of the style would be Newcastle Brown
The 6.2% ABV of the Gentlemen's Relish is nice, and it's light-bodied enough to be sessionable - even in the San Antonio summer heat. Come enjoy a glass!
