I brew to ensure I have a nice mix of styles available. I aim to have 7 or 8 different beers ready to drink at any time.
A few lagers, a mix of PA's and IPA's in various strength's and a stout and/or porter or 2 depending on time in the cycle.
Can be as many as 10 brews in the cycle, but that means there may only be half a dozen of 1 or 2 batches.
I hate drinking the same thing over and over and its unusual for me to drink 2 beers the same in a row. Unless its my brew buddies batch, he only bottles in longies so swap beers are a bit bigger. Taking that into consideration there can be up to 12 or 13 different brews all total...usually have 5 or 6 of his batches floating around as well.
