Did my first outdoor brew last weekend (on a deck outside our kitchen). Being able to hose down my "kitchen" is a big plus. If I ever build a house, it will have a hose-down kitchen!
The issue that kept me hopping (no pun intended) was boil-off. It's a whole new setup for my brewing, a Bayou Classic SP10 and a 8-gallon kettle (intentionally small, because 4 gallons is about the largest I brew, and more often 3 gallons). I supplemented my kettle with water twice during the boil-off. In the end I hit my quantity and my numbers, but I'd like to get this more predictable.
Is it possible to get a better estimate of boil-off before my next batch by bringing water to a boil and then boiling it for a set period of time? The variables I thought might throw this off are a) the viscosity of wort vs. water and -- I'm guessing even more significantly -- b) the issue of how much propane to use. I suspect I had the boil too strong. It was fun to see that wort roiling, but I suspect that's not necessary.
