Great for wine. Great for beer if you pre-filter out the hops/trub. If you leave all the gunk in then it can clog up at the bottom. I used it for a few batches of beer with success and then did some wine before retiring from alcohol.
Can't find the original stopper, the replacement does not have a hole for airlock so you'd have to drill a hole or buy a new stopper.
Northern Brewer sells them new for $199, I'll take $115.00 shipped.
