Default 2nd All Grain Success

Did my second AG today. No major issues to report other than a lower than expected sparge temp. I wanted to sparge with 168 degree water, but by the time I transferred it from my kettle to the tun, I lost about 5 degrees. I just need to tweek my process a little to fix that , but shouldn't be a big issue I dont think.

It was Guinness Draught Clone and it looks beautiful.

I hit my numbers pretty close:
Expected OG: 1.036
Acutal OG: 1.038

I think my efficiency was around 81% according to Beersmith2. Could someone help me with the formula and verify that.

Pre-boil OG and volume: 1.028 and 7.9 gals
Post-boil OG and volume: 1.038 and 5.5 gals

My first came in around 70% efficiency. Anything I should look at to keep consistency or is this not that big of difference. Moving to AG was the best move in home brewing that I have made. Though its more work, it is much more fun!!!

Cheers

How much grain did you use? Efficiency is measured at percent of total theoretical extraction maximum. At any rate congrats on a good brew

Doh... I knew that (bangs hand on head)...

I get 77.8% efficiency for that (using 1.035, 1.032, 1.025 for three ingredients, respectively ) very nice!
