Notes

Some new stuff going on this time - first off, this marks a return to the All-Grain brewing style, and hopefully with some better results. Additionally, I built my own water from some reverse osmosis water to match a London water profile which I also compared with a desired outcome on a couple of additional calculators. Finally, I have upgraded my sanitation procedures a bit, which is extremely nice - started using some Star San instead of bleach and already I notice a big benefit in my ability to use stuff right away without having to rinse. And, since it is made for brewing, there is little risk that it will mess with my beer at all. Going to try some different approaches to cleaning the SS kettles, too - we shall see.

Building water resulted in a good bit of crap accumulating on the mash water pot, but it should rinse off pretty easily with hot water, I would hope.
