For those of you looking to get free pickle buckets, I have done this and have had an incredibly hard time getting the pickle smell out. Even when you think they smell ok, run some water in there and let it stand. To me I still smell pickles.
I brined a turkey in one I had washed multiple times, and left to air out for month. I gave it a sniff, seemed ok so in when the water, salt, sugar and the turkey. It smelled like pickles in my fridge the next day. Turkey came out ok, but not sure a beer would.
Go to a deli, ask for buckets they get frosting in. Much easier to clean and the smell does not linger.
