I think I have this conversation more with myself than with my wife. Every time I think "that's it", there's something else I "need". Even though I've been cranking along along an AG now for awhile, I "needed" a 10-gal cooler MLT...and an oxygen regulator/stone...and some stuff to make "better" yeast starters, and maybe freeze yeast...and of course I
have to grow my own hops, so here come the rhizomes. All of this in the past couple weeks. And still, I look at my large collection of haphazard, mismatched, fully functional equipment and think "damn, a rolling 3-keggle brewstand would be pretty cool"...and the next house will just have to have a dedicated brew room, plumbed for natural gas. And maybe a walkin cooler/freezer...
I don't think my wife minds much...as someone else said, it keeps me around the house, out of trouble, and she likes the results of the effort. I also have a bicycle that always "needs" something...she gets a little crosseyed when fedEx brings bike stuff AND beer stuff on the same day.
But....she was the one who suggested the keg setup (she hated having all the bottles around, and the way bottling time took over the whole kitchen). Of course, now two taps seems totally insufficient
If she complains, I'll just remind her about the summer we timeshared the sailboat...this is all peanuts compared to that. Wait....hmmm...a floating brewery....
