Mini-Mash efficiency
« on: October 18, 2009, 09:13:03 PM »
I did my second mini-mash today and this time even added a pound of 2row pale malt to the grain bill. And again the measured OG came 1 point under the predicted OG. Now on the first batch I knew my brewhouse eff would not be 75% - so I made a guess of 60% and figured I would have to adjust it up or down over time and more data.

So a pair is not a full-house and more data is needed. But - by saying my efficiency is 60% really means I have to use a bit more grain to hit the mark. Is that a correct way to look at it ?

Do I need to make any more corrections or call this close enough ....

My efficiency was poor with partial mash and even full mash in the kitchen.  It's tough to get a good solid rinse of the grains, and tough to keep the grains at 168F.  I think I used 65% in the software. 

As you're dialing it in, I'd recommend using a lower EE% and adding water to dilute, which is much easier than needing DME to boost.  And constantly tweak your rinse/sparge methods to improve the EE%. 

One thing I did was get the boil going with maybe four gallons of wort (in typical 5 gal pot), and then after the boilover threat had passed, I'd add final runnings to top off pot up to maximum safe boiling level.
