The wife loves my beer---even more so since I built the kegerator and she can pull a pint whenever she wants and doesn't have to worry about me refilling the fridge with bottles. She's even a bona fide hophead. We've been married for a year and a half, been together 10 years...and still have separate checking accounts and credit cards. She likes it that way, as do I...we never get into arguments about $$ for brewing stuff, mainly because I pay for it all and do all the work and all she has to do is put a glass under the tap and pull the lever, so it's not such a bad deal for her. I was a bit surprised at how supportive she was of the kegerator project. She would actually hassle me to get off my ass and work on it. Now
that's love!
We've run into some obstacles...such as stacks of ugly cardboard boxes full of beer bottles sitting in our finished spaces...or brewing when I should be doing something else. But over time, I've gone out of my way to come up with better storage options, and have consolidated my equipment as best I can to keep it out of her way. I've also gotten my brewday down to about 4 hours for a batch, and will wake up really early on a Saturday just so I can get it done before lunch. She sees this effort and is genuinely appreciative, and has come to trust me 100%. For instance, we were sitting around on Friday night with some friends and one asks what we were doing this weekend. I said I was thinking about brewing on Saturday, wifey gets a surprised look on her face, and my friend says "uh oh", expecting her to scold me. Instead she says, "no, it's cool, I trust him. He gets up early and does what he has to do." Word! She rarely participates directly in the operation, but she's at least somewhat interested, which is nice...all around, it's a healthy situation. Which will all change when we decide to procreate, but that's another story...
To the OP...communication is key, as is showing a genuine effort to minimize the negative effects on her. Oh, and Go Skins!
