Two empty kegs in a 2-tap kegerator makes for a sad brewer.
As my sig currently shows, I've actually got quite a few things going in my pipeline, and I'll be putting the EdWort's IPA in the keg on Saturday. But this was only after figuring out my problem in mid-January: both kegs were getting low, and I didn't have any beers going to fill them! Plenty of wine/cider/mead batches, but nothing to keg. The bottles I have are few and far between; straggler remnants from previous batches. I don't generally bottle (I'd much rather siphon once from primary to keg), but that may need to change so I'm not limited by keg availability.
So here we are in mid-February and the IPA is almost ready. The Irish Red will be another 2 weeks, per the Northern Brewer recipe. I suppose that for maximum turnaround I should have busted out a low-grav Pale Ale and a Hefeweizen, but IMO it was too early in the year back in January.
I'm going to pay more attention to beer-pipeline considerations in the future (I've got rough brewing plans for the whole year now), but I'm curious: how do you plan ahead? What sort of keg turnaround do you generally presume? Do you have any tools or rules of thumb you use?
If you get overly optimistic about kicking a keg and you wind up with a beer ready before the keg is, do you just wait, bottle, fill growlers for friends, throw a party?
