Over the decades my gravities have gradually diminished, then plummeted. It's been years since I've brewed above 1.060 and I seldom blip above 1.050 anymore.
I find I enjoy the challenge of making small, flavorful beers because it really is a challenge and there isn't much beer there to hide your flaws. You've gotta be on your game with small beers, really on your game.
Additionally, I like to keep my kegs turning over regularly. I used to brew a big Burton Ale for Christmas, but as that keg kept hanging around deeper into the Spring, Summer, and eventually Fall of each following year I realized that not all traditions are worth hanging onto. I've flirted with the idea of getting a 3-gallon keg, but it would still get in the way.
Style-wise, I still think of my brewery as being UK-focused. However, during COVID I decided to tackle N. American fizzy yellow swill, perhaps the most difficult style of them all, and that's diluted my prior UK focus rather considerably.
Styles: UK bitter, mild(!), brown porter, brown ale, pale ale; N. American fizzy yellow swill; a spattering of proper continental lagers and US pale ales.
[Edit: I've also failed to jump on the RO water+spreadsheet water calculation bandwagon. I enjoy brewing with the seasonal rhythms of my DC tap and rejoice in my ability to adjust on the fly to its occasional wild spasms. It's a fun puzzle to crack, not an obstacle! I love that unpredictability, it lets me flex my knowledge--and sometimes it humbles me. I love brewing with wild, uncontrolled water. Brewing with RO? That's for people that take bus tours and have exotic dinners at the Olive Garden. Yeah, no thanks.]
