+1 to this. Every batch I have brewed so far has looked just like this. Sometimes a half inch fuller, but not more.
I always brew 5 gal batches by boiling approx. 3.5 gal with the LME and other ingredients and then top up the Primary bucket to exactly 5 gal. When I rack to Secondary carboy it usually looks like the above. When I rack to Bottling bucket it's even less. In other words, I'm losing a significant portion to trub.
What's the solution to this? I know I could top up the Primary to 5.5 (or more) gal. But I like my OG values; they tend to be between nominal and right at the top end of the predicted range. How much would an extra half gal water down my brew? Are there other good solutions to this? Can I somehow increase my extraction (Extract brewing here) to compensate for additional top-up water?
At some point I'm going to brew a "big" beer that needs to condition in Secondary for several months. At that time I suspect I should be more concerned about reducing headspace. Should I avoid messing with additional top-up water until I tackle this kind of beer?
