I just had to share.
Just got done brewing a saison using Death brewer's instructions for a mini-mash.
Using the formulas from "How to Brew"
by John Palmer I did a multi-step. Since I had 1.5 lbs of flaked wheat, 1.25 lbs of oats and .25 lbs of corn grits I thought it would be a good Idea to have a protein rest. I shot for 122 degrees for 20 min 140 degrees for 40 and then I used the multi-pot rinse technique Death brewer describes; I shot for 158 degrees there.
All my temps came out low 115 to 140 to 150 respectively. I squeezed my grain bag out thoroughly. I figured I should get around 75% efficiency. I only take one hydrometer reading and that is right before I put the lid on the fermenter. So, I had 7 lbs of Pils LME and 2 LBS of inverted sugar.
If I take the sugar and LME out of the equitation I figure I got something like 70% efficiency.
THAT IS SO SWEET!
Here are the numbers if you want to double check my math.
7lbs pilsner LME = 250 PPG
2lbs inverted sugar = 90 PPG
Max ppg for other grains used in mini mash
2.5 lbs 6 row malt = 87.5 PPG
1.5 lbs flaked wheat = 54 PPG
1.25 lbs oats (mostly quick oats) = 40 PPG
.25 lbs corn grits = 9.75 PPG
.25 lbs dark munich = 8.75 PPG
My actual OG was around .080-.081.
If I take the LME and sugar out of the equation I have a max potential PPG (acording toTable of Typical Malt Yields from John Palmer's book
) of 200 PPG.
If I take my .080 reading and mulitply by 6 gallons I get a PPG of 480. Taking out the LME and sugar again leaves me with 140 PPG yield from my mini mash. 140 is 70% of 200.
Now go have a beer since I made your head hurt!
