So, I took so long to rejoin my own thread because I was buying a barley crusher and a BIAG custom made bag from

AG here I come!!
My water boils at 192F. I guess I get a little extra boil off due to the extremely low humidity, but I've never brewed anywhere else to compare to. Any of you desert guys have extremely high boil off?
I have a lot of improvement ahead of me, especially with water volume levels. It's tough brewing outside with the low temps and wind. It seems to do weird things with the propane flames. I've had very different boil off amounts between my 3 batches, I think due to the wind.
I probably have slightly lower hop utilization, too, I'm told. I'm not at the level yet where I can reliably test different factors, so I just boil my bittering hops for an extra 10 minutes or so and call it good. I'm just now planning my 4th batch ever, and it will be my first all grain and BIAB.
Yeah, Breckenridge BrewPub is at ~9,600 ft, so quite lower. I drive past it every day on the way to work or snowboard. I think there is a small brew pub in Winter Park that might be higher, but I'm not sure about that. (Edit: They are at ~9,000 ft) The 3 other breweries in Summit County are probably all higher than Winter Park, and lower than Breck.
I think the best part of brewing where I am is the water. There aren't any permanent residents that live up hill from me. I have a simple well, with a simple paper filter, and no chlorine or any chems needed. It is f'ing delicious right outta the tap. I might test my water some day, but I'm not that dialed in yet for it to be significant, I think. I've only ever tasted my first batch (Great Lakes Eddie Fitz tribute) and it was way better than I expected, so I doubt my water has any serious issues.
