Beer #4 for NHC 2018. This beer is my first decoction and I did a dry run a few months back to work the kinks out. It went really well and the beer turned out awesome so I didn’t change anything for this run. It went well again and took 1st place in the first round of NHC in Tampa. Many years of trying to get a Hefe to finals and I finally got it done!!! Really cool. My only issue is that the beer cleared a bit too fast. The only change I could make would be to drop the whirlfloc so I think I’ll try that for the finals. Hmmmmm…..need to to think on that.

Notes
Single decoction
Mash in at 105f raise to 112f immediately and hold for 10 mins
2f a min up to 126f for 10 Mins
Raise to 149f and hold for 5 mins then pull 1/3rd as thick decoction and leave main mash at 149f while handling decoction
Slowly raise decoction to 158f and hold for 20 mins and then boil for 10 mins
Reincorporate decoction into main mash slowly and stabilize at 158f for 10 Mins and make sure it passes iodine test else hold till done converting
Raise to 169f and hold 10 mins
Chill to 58f
Pull 4 gallons to fermenter and then pull 2 quarts in mason jars for speisse at bottling
Oxygenate for 60 secs with 0.5 micron stone and o2. Raise to 63f over 24 hours. Hold for 1 week. Raise to 68f over 24 hours and hold through two weeks.
2-13-18 brew day went well.
mashed in @ 106 and then immediately started to raise to 112F (set HLT to 122F and once to 108F lowered HLT to 117F) and started 10min timer once I hit 111F.
then set HLT to 136F and got MLT up to 122F then turned HLT down to 131F and started timer for 10mins when MLT hit 125F. once up to 126F i put in calcium chloride and lactic acid. (low pH inhibits ferulic acid production – or so i’ve read 🙂
set HLT to 159F till MLT got to 145F then set it to 154F. after 5 mins I started the decoction. MLT is 7.25G so 1/3rd is about 2.4G of thick decoction. i scooped out till MLT was down to 4.85ish G.
I set the induction cooker (where i do decoction) to the highest setting (10) to get it to 158F while constantly stirring then set it to the lowest setting (1).
after 20min i set induction cooker to highest setting to get it to a boil. this took a while but once to a full boil i let that go for 10 mins while stirring the whole time. I overshot b/c i did not turn dow the setting fast enough and the bottom got really hot.
i collected 2 x 800mL speisse sample in quart mason jars before pulling off 4G to the carboy.
i pitched the full starter that was in the fridge set to 57F
2-14-18 @7am no bubbling
@10am nice kreusen and steady bubbling
2-15-18 2″ kreusen and strong bubbling
2-16-18 started to slow
2-17-18 slow steady bubbling. still big fluffy kreusen.
