Notes
8-18-16
Mashed at 152, reached the very capacity of the mash tun, pulled out about 1/2 gallon of liquid to get the grain in. Stirred thoroughly and covered. Stirred at 30 minutes in. Batch sparged with 3.5 gallons of strike water, at 170. drained tun as slowly as possible, repeated and drained painfully slow. While doing that, I used the leftover spare water to boil and record through the plate chiller to sterilize. Hit 1.066 preboil gravity and 14 gallons volume.
Added hops at 60 min, subbed 2.77 ounces of northern brewer for the admiral hops, home-brew heaven didn’t have the right hops or the substitutions available.
Once it hit boil, turned the power down to 70% to achieve a gentle rolling boil. Ended up throttling between 70 and 80%. Added whirl floc tab at 15 minutes left, sprinkled in some irish moss for good measure. After 60 minutes of boiling, hooked up the plate chiller with the thrumometer and ran about 74-76 right into the fermentor. Probably should have recirced back into the kettle to bring it down another 5-10 degrees.
OG: 1.072
Final volume= Didn’t measure but put at least 5 1/2 gallons into each fermentor and had at least 1/2 gallon left over, so 11 1/2 to 12 gallons
debating wether to oak age 1 batch and vanilla bean the other or do them both to one and blend with the other?
FG: 1.016 ISH. Added 2 vanilla beans that were scraped, chopped up and soaked in 2 oz. of vodka for a couple days. Stay have over done the vanilla flavor a little bit, was hoping for a faint note and it is right in front instead. Next time i might not use so much booze, or only one bean.
The other carboy got a french oak spiral soaked in Makers Mark bourbon for a few days. Taste is good, not super p\p front, more nuanced. May blend with the vanilla to calm that one down a little bit.
Next time this should be mashed in for a fuller body, maybe at 156.
Follow up- Vanilla was so powerfull I never finished the keg, and still have half of it on 9-17-17.

10/28
Mashed in at 156-157
Added the 8.5 mL lactic acid to sparge water
mash lost 2-3 degrees over the hour… garage temp is in mid 50’s
first running is: 1.095
second running is: 1.058
Third running is: 1.038
A note on volumes… had more run off than I could fit in kettle, have around 15 1/2 gallons collected and still draining tun. recovered around 5 gallons at each run.
preboil volume is 14+ gallons
preboil gravity: measured with a hydrometer at 1.060
postboil gravity measured with same hydrometer at 1.065…. strange
Made a big mistake and started filling the spiedel fermenter without placing a cap on the spigot port, and lost an unknown volume of wort down the drain… estimating at around 2 1/2 gallons.
gravity check at 7 days is 1.018
