That was a mess!!! My first all-grain did not go well at all. I posted a thread earlier on a stuck sparge, so a few of you may have read that thread already.
Everything started off alright. Pre-heated cooler, added grain, then 170F water. Hit my desired mash temp of 150F dead on. The cooler held that 150F for the entire hour...never lost a degree.
Vorlaufed(sp), then slowly drained off the wort. About a gallon went really well, then a STUCK SPARGE!!!
Tried my air compressor to blow back thru the line, that didn't work. Ended up just straining the grains in a 5-gallon paint strainer.
Pre-boil gravity was 1.028, was supposed to be 1.036. I then boiled the wort, no problems there.
I used my new copper wort chiller. It took about 20-25minutes to cool it down. I was not happy with the performance of the chiller.
I am having a very difficult time figuring out my efficiency. I think it is VERY low. Here are my numbers. Maybe someone can help me out.
9lbs Pale malt- 2 row
.50 Crystal malt-10l
.50 vienna malt
Pre-boil gravity= 1.028
Post boild gravity=1.051
Total of 5 gallons into fermenter.
I am not sure if you need anymore numbers. If so let me know and I will post them.
Can someone calculate my efficiency for me?? Thanks!
I do have Beersmith. Under the heading Brewhouse efficiency it says "Actual OG" If I put my pre-boil number in there, my eff. comes out to 36.17%
If I put in my post boil gravity I come up with 65.88%
Any information would be appreciated.
