I was at a standard micro brewery yesterday. 12 different IPAs on tap. One Kolsch. One Amber. One dark amber/porter. One oatmeal stout. Two ciders.
I had the Kolsch first (thank god people are making this amazing, highly drinkable and pleasant beer!), and then the amber.
But, by and large, American beers are a waste of time. Undrinkable pucker-inducing bitter swill.
Brewing has been around for centuries, and there's a reason people made pilsners and kolsch and dark beers; they were drinkable by anyone at any time. And there's a reason people make IPAs; they are the easiest and shortest time to brew, so you can churn out more of it in less time with less skill than any other brew. It's just economics with good marketing backing it up.
But it still tastes terrible.
