Hello, I recently brewed a 1 gal batch of the Irish Red Ale. I used a blow-off tube for the first 2 days of fermentation which was very helpful as I had a lot of foam bubble up and out but my question is, should I still be seeing left over foam in the top of my carboy? I removed the blow-off tube on day 3 when the foam was no longer going down the tube and replaced it with an airlock but there is still quite a bit of residue left at the top almost 2 weeks later. Bubbling has died down almost to 0 in the airlock btw and there doesnt seem to be much going on in the fermenter at this point.
Thanks for your help in advance!
