I'm some of all of it. I've always been a cook. I like to create food, enjoy it myself and, more importantly, share it with friends and family. I have a reputation for outstanding BBQ, I win about 90% of the work cooking competitions, and my hardcore beer nerd friends (they travel on beercations, spend hours waiting in line for limited releases, host shares with high end beer from all over the country, etc.) all think I should open a brewery. I love that I can make things that people love. I read and try to learn constantly to improve the quality of what I make, which takes me to point two.
I'm a learner. I love learning new things and tackle new hobbies voraciously. I got into sailing in the 80's and by the end of the decade I was part of a national championship sailing duo.
But there's more. I'm an engineer, woodworker, DIY guy who fixes my own appliances and such. I don't like work that adds nothing to the result. In other words, I'll go to the nth degree to get a better result, but all things being equal, I'd prefer to make it easier. For example: I currently have to store all my equipment in the south end of my basement, but brew in the garage in the north end of the house. I have to go halfway south across the house, down stairs back to the north, then double back to the south end in the basement, then back north to the spot under the stairs to get and return the equipment. I also have my fermentation chamber in the south end of the basement. I drop 30-60 minutes each brewday hauling crap around. That's extra work that adds nothing to the product and I want it gone. I also have to go in and out of the garage a billion times to get to the sink when cleaning. Wasted effort, huge PITA.
Also, living in Iowa, brewing in the garage during the winter sucks...big time. I want to brew in an environment that's as nice as the one I cook in.
I love milling, mashing, sparging, boiling, measuring, recording, etc. I love the sights and smells. I love the art and science of making recipes and following them. I don't care if my brew day is 6 hours, as long as it's actually brewing....not hauling, washing, setting up and tearing down. So, I'm trying to streamline my process to minimize the things I don't like and retain the things I do like.
To that end, I'm planning an electric brewery in a dedicated space with facilities to store, brew, ferment, package and clean all in the same general area. That minimizes the crap and should make for an enjoyable brew day.
Also, I mostly brew alone because I generally prefer it. I always feel like I have to entertain people when they hang out while I'm brewing and I inevitably make mistakes because I get distracted. I would love...LOVE....LOVE to have an actual brewing partner. Someone who knows the rig, knows the process, understands the recipe and can help without being told what to do. I've had a couple friends who dabbled in brewing, but quickly decided it wasn't their thing. I've tried to get my wife involved (she loves my NEIPAs), but she's not really interested.
So, that's why I brew, and that's why I'm also a person trying to streamline my day.
