I came across this today: Kentucky Common Beer - Wikipedia, the free encyclopedia
This looks interesting if only for it's rarity.
The question is how do I prepare a sour malt?
I've heard of people using cold water baths to cool down wort, but never to lager. It's actually a pretty clever idea.
Wrap the container in a plastic garbage bag - if you have shrink wrap even better.
Just don't tell the neighbors :).
