I just bought a cold wort transfer pump from Williams Brewing:
Using it for the first time today, I noticed that there seemed to be a lot of bubbles being whipped up during the transfer to my keg. This obviously caused a good amount of concern on my part. A couple of questions:
First, does anyone else have this pump (or a similar one)? Do you see the same thing when you transfer fermented wort?
Second, are these bubbles air or are they CO2 coming out of solution during the transfer?
Third, if they are air bubbles (this pump does seem to move a lot of air along with the transfer as the filter housing never really empties out the air bubble during operation), would this be a problem in the keg? A little more info regarding this - I do not secondary, but rather transfer to a keg and allow to condition for another week or so at fermentation temps. Would this action clean up any additional oxygen that the transfer created?
So many questions...
...your experience would be helpful. Thanks ahead!
