OK, here we go.
Mashed in two different coolers, as the huge one brought by a friend wasn't as big as he thought
Turns out that six batches is a WHOLE lot more water management than I thought. By the end of the brew session we ended up with about 5.5 batches worth of beer. Just too much work and too many new people to teach and be exact at the same time.

Mashing in the second three batches (15 gallons).

Sparging. The second tun didn't have a spigot so lots of transferring. Lots of work...

Weighing the hops. I had Centennial as the boiling hops because I didn't have enough Styrian for a single hop brew.

Blue Angels Intermission

Low and FAST!

Starting the boil. We did two 10 gallon boils and two 5 gallon boils.

Bystanders and helpers. Got real crowded and the attention span was wavering.
16 hours later, fermentation is kicking off. Lots of trub in this one, not sure why. Should settle out though.
This was my batch and I doubled the aroma addition so maybe that's the cloudiness.
All in all it was a great night. 6 batches brewed in 6 hours from water on to garage doors closed. Created two new brewers who actually opened their kit boxes last night. Water, water, water. Probably a bit too much work for the two of us who are the main brewers. But I'm not going to let anyone go home without a full fermenter.
