I love how the "deer in the headlights" look comes across MOST people's faces when they want to talk to me about brewing not just the wife's. The problems everyone is having is NOT as isolated as they think.
I have been working to get my wife involed with brewing for over a year, closer to 2. I went so far even as to make a batch up and tried to get her to pour the yeast in, technically making her a brewer... yet another glorious crash and burn... then it slowly happened... I started going to homebrew club meetings.
It only took me coming home talking about socializing and trying new beers INSTEAD OF BREWING DIRECTLY one time and she wanted to come to the next meeting to check it out. Next month we go to the meeting and have a GREAT time. The next day she brings up how much fun we had and I ask if she wanted to become a member. She took a few minutes and then agreed.
A few months go by and she is reminding me "to bottle a few up for the meeting" and is looking to a hobby that is not brewing. I had been planting the seeds of starting a hobby that produces something, like homebrewing. She really wanted a hobby that was what homebrewing is to me, for herself. We talked about cheese and she had tried a few others that she did NOT like. Then after a few well designed subtle hints, she wanted to try soap making. She did and loved it.
Now she "babbles at lengths" about soap making, the processes and equipment. I have a minor understanding of what is going on but I let her do her thing and she lets me do mine. This gives us each the unique perspective of "what it is like to be the other person". We are still in the homebrew club and she has no interest outside the club (and drinking it) about homebrewing and I feel much the same about soap.
Her soaps are great, get me clean and make me smell good. I have no interest in ever making a batch, it is just not "my thing". We both have a good laugh when one of us gets lost in the others "hobby babble" and that just goes with the territory of being passionate about something.
In my experience I would suggest you try to encourage ANY product producing hobby and see what happens.
