I've been fermenting my second batch in a MrB on a shelf in the laundry room. Today I noticed when the washer was on a spin cycle it vibrated the shelves that the beer was on. Is this a bad thing?
Bah...I was expecting something more titillating! How long has this MrB been sitting? If it's been less then a week, then no worries at all. If it's been over that, I still don't think you'd oxygenate it that much (you wouldn't introduce that much oxygen unless you really shook it). Since MrB is also a relatively small batch, I suspect you'll consume it quicker then any oxydation off flavors will manifest themselves.
