Thanks for that! It was definitely a bit chaotic for the first brew since I didn't have a process down yet. Good to know that wasn't just me! I took notes as I went and made a list of things to get to make things less hectic, like longer hoses for chilling so I don't have to wheel the Brewzilla over closer to the sink (I was used to brewing 2.5 gallon batches on the counter right next to the sink), a fan to better direct the steam out the window, etc.
Mash temp control was fantastic. I'm glad I did a ton of reading and YouTube watching about the settings, because that worked great. Efficiency was my biggest disappointment -- I was hoping for 70%, came in at 60%, but now I have that data point and can do better next time or adjust recipes accordingly. I also ordered a brew bag to give that a shot since that's what I'm used to doing with a kettle and got way better efficiency.
First brew day with the initial cleaning of the system, resolving a leak in one of the hoses underneath, having to do a 90-minute boil since my volume was high, and a bunch of other "first-time figuring it out" stuff clocked in at 8 hours. Hoping to get it down to half of that next time.
