I prefer to always have a multi-pack case of whatever craft brewery I can find in a store. Latest one was a Pyramid 24 pack from Costco that had a winter ale, octoberfest, ipa and barleywine. Also a Blue Moon multipack with some spring ales in it. I prefer to always have something different, rare to buy the same beer twice.
I will buy and try any barleywine I can find, but those never last in my fridge for very long!
My go to in a store (like target) would be Blue Moon or Newcastle if I can't find anything else more interesting in a pinch.
