You know you did it wrong when you max out one hand counting the things that went wrong.
1) Mash tun was not warmed up enough so I guessed at new strike water temp and overshot mash temp by 6 degrees! Had to stir and added ice cubes to bring it back down.
2) I decided to see how fast was too fast for an underlet and got doughballs
3) When adding initial hops, and a boil over was imminent, I turned flame up not down! So I boiled over the first use of my new brew kettle.
4) At 30 minute mark I discovered I had added 10 minute aroma hops (Fuggles) at 60 minutes instead of Northdown. So I added the forgotten hops then and of course skipped the 10 minute hop addition
5) And to finish it off I broke hydrometer when getting OG
I still expect it to be a good beer but.....
