Like ultrasonics which causes micro cavitation and vacumn cavitaion a much more aggresive form of forcing movement and contact. Aeration may be a bit slower but the outcome is the same. I do not think that it can be overdone. As it is so gentle. I use this method for up to 6 months before laying down the cask, then after ageing, for a month to freshen up and stir the cask. Our new whiskey which is being released later theis year is Penitants Run it recieved a total of 8 months on the bubbler as we call it and we tasted it last night when we hosted the Single Malt club for a tasting and tour, They seemed unanimous in agreeing it has made a really nice spirit. we got a lot of deposits and pre-sales so I guess the proof is in the pudding ...people do like the style.

I'm very surprised how much it has mellowed

Can't go into it too much at the moment...bar is full of customers...but be aware the attachment photo is of a filter...not an air pump. The brand does not matter so much I tend to buy large pumps with a variable air volume knob so I can control the airflow... back to work for me. take care.

r.c are you not worried about your spirit coming in contact with plastic? I agree, it would be good for transferring wash.
