So glad I called them. Super cool guys. They won gabf with that, pretty impressive. They offered to send a sixer right away and I didn't ask for that or anything. He said its an unfortunate part of this recipe, if the beer sits to long that happens. The can was from june. They dont want to change recipe though, cant blaim them after winning gabf. He said their helles won silver this year and another got a bronze. Their response was first class and I will try the helles and have no problem giving a fresh can a try. Super class organization, good on them.
