Had a few similar conversations with my mates / local landlady (who both sort out used bottles for me), most start something like, when are going to bring some hb in. To which I reply, the fermentation process can take between 3 & 10 days, then a day to bottle/keg & anything from 4 to 12 weeks for the beer to drop clean/condition.
They're beginning to understand now, as I've been doing my Belgium brews for Xmas, all of which take 6 to 8 weeks to be at the optimum.
In short, unless you're brewing 50l per batch, once or twice a month, you'll never have enough hb to go round.
My wifes now into my hb big style, which now means my 20l or so of brew, pretty much results in a net 8l to myself after, I've given some away to family friends.
I'm already getting ready for xmas i.e 7l of Bruferms Xmas brew (6%) & 18l (2 kits) of Brewferms Abbey (8%) + tonight I'm going to kick off a Brupaks bitter, followed by another kit a week later & possibly a lager for new year.
So brew, brew, brew and brew somemore, get yourself 4x 18l cornys, beer gas, plus a couple of 9l cornys for take outs & the jobs a good un.
