In the end I would buy whichever one is the freshest. But if they're both reasonably fresh I'd go Red's Rye all day.
Bitter American has moved towards one of my favorite sessionable beers, Im voting for 21st on this one
How many do you want to drink in one sitting? If a couple, go with the Founders. If more, go with the Bitter American.
buy the red's rye 2day check the neck for freshness drink some its great, this weekend pick up Bitter American and drink a few very sessionable
Definitely Founders. If you opt for Bitter American, check the date. It's awesome fresh, but those hops not only fade with time, but the taste gets pretty dang awful in my experience. as such, i have 2 cans in my fridge and I plan to offer them up to folk who don't give a fuck
