Hi, First post here. I've done lot's of reading already but i just can't figure out why my mash efficiency/brew efficiency is so damn low.
I just did my 4th all grain brew yesterday. I was going for 1.052 OG for a 6 gallon batch of wheat beer. At the end of the day I read 1.032 OG on my hydrometer and there was under 6 gallons due to boiling and other losses.
Grain:
6.5 lbs Wheat Malt
4 lbs 2-Row
1 lb Flaked Wheat
0.5 lbs rice hulls
=12 lbs
In a 6 gallon plastic bucket the grain bed is about 16 inches deep with rice hulls integrated throughout.
I add 12 liters of 130*F water and rest for 20 minutes at 122*F
I add boiling water to bring temp up to 155* for 60 mins
Temperature is down to 150* so I add a liter or so of boiling water and
recirculate for 45 minutes.
I drain wort at 1 liter per minute and collect 7 gallons.
Everything went very smoothly. I only tested the OG at the end of the boil so sorry I don't have more information there. Grains were milled at the LHBS here in Vancouver which has a good reputation.
I've not been happy with my efficiency in the previous batches hitting between 50-55% even with some late addition malt extract.
1.032 is like 40% efficiency. Am I missing some important aspect of mashing grains?
