And then give her a vacuum for her birthday...
Right after I read this, I was in the breakroom and one of my coworkers was saying that her husband bought her a vacuum for her birthday. I almost laughed out loud...she was really happy....to each his/her own.
I think the important thing here, and what I suspect will make the biggest impression on her is that you are sharing something important about yourself. Not saying you should brew something crazy that she will almost certainly not like, just that what you choose to brew with her is not as important as asking her to brew with you. opening up and allowing her to see a real aspect of who you are is going to win her over way more than what style beer you choose.
and +1 to euge, feed her, feed her with wonderful beautiful food that you crafted with the same care and love that you craft your beer with and she will be impressed.
Nicely put and totally agree. I think its great if there is interest in brewing together. My wife loves that I brew and loves my beer, but we kind of clash while cooking and brewing. Branching out into different beers may take a while. For a while my wife only drank hoppy beers, then she started liking other beers and is only recently liking unusual ones. She still isnt liking my no pants thing, but it is something she has become used to by now. An English Brown is a good choice. Thats one of the non hoppy ones I made that she tried and liked. I brewed a Southern Englsih Brown because I wanted to focus more on the malt/fruit than the malt/nut flavors.
