Have bottled several batches now (about a dozen all grain) and all of them have carb'ed up with no problem. My question is what effects the bubble size? It seems that early beers seem to have larger size bubbles and longer aged beers have smaller ones. I understand that head retention is related to brewing temp and also to some of the proteins from brewing. So, if I let my beer bottle condition longer, does that mean smaller bubbles? I understand different beer styles have different head profiles so I am talking in general. How does the amount of time chilling effect this?
