Notes

4/18/2020- Bottled the keg, approximately 4.25Gallons. The numbers are not totally accurate, as these are the OG/FG of the 3G batch + the 1.75G batch mixed together. Next time I will need to examine the mash and boil as a new beer, but the taste is amazing.

4/4/2020-This went into the keg with 1/2cup sugar+1cup H2O and 1 packet of champagne yeast to carb up a little. After 1 week, it went into the keezer and onto the gas to finish up carbonating.

1/18/20- So I am brewing this again, 3G, and then add the remaining bottles (1.75G unfermented/unfinished) into the fermenter for re-fermentation with the new wort at high krausen (It worked!). I will be using an Irish Ale Yeast Starter and have a backup of A10 Dark if this doesn't ferment out mostly in the first week. It fermented on 2oz. of oak for approximately 2 1/2 months before kegging. It is really smooth and really alcoholic.

This never fully fermented. I added several yeast strains into it and it just hung up, not even carbonating in the bottle.

**I am turning a partial-mash dry stout into an all-grain imperial stout. I like the flavors of the original, so I am just trying to intensify it and make a smaller batch to see if it works.

I am using first runnings for this recipe. The partigyle or second runnings (i.e. the batch sparge) will become a lower ABV beer.

Ok, so far, here is what I have:
Strike water of 170F, 6G, and a temp in the mash over 90 minutes at 162-160F. Higher than I wanted.

Transferred 5.25G of 1.063 wort into the BK, will boil down to about 3G for the fermenter. Not sure how long I will have to boil to get enough evaporation.

My burner evaporates about 1G/hour. I lost a little to boil over a couple times, not much, maybe a few ounces. There was a lot of break left in my strainer, more than I expected, from a BIAB. I think this recipe might be better as a standard dry stout instead of an imperial next time, I.e. 5G batch with these ingredients.

Bottled 2.2 Gallons
