So were you able to go from 1.067 to 1.005 mashing at 152? That is a huge 92.5% attenuation?

I went from 1.060 to 1.008 with 100% vienna malt mashed at 152* and pitched onto a US-05 yeast cake.

Yes, I was also suprised by the attenuation. I've always loved the wyeast 1056 yeast. It's a very aggressive yeast that always seems to get the job done. That's why I didn't feel the need to do a starter as I do with most other yeasts.

My Beertools program calculated my final gravity out to around 1.011, so I was a little concerned when it hadn't stopped fermenting after about 9 days. Couple days later it hit 1.005.

My only problem with this batch was that my efficiency was horrible. It came out around 60% I believe. I'm not quite sure why it was so low, but I'm using a new all grain system so I'm still trying to figure out the bugs. Also, I used the mill at my LHBS to crush (which is what I think caused it) because mine was out of commission.

Efficiency is a whole arena in itself, my guess is that if you are just starting out with all grain and you suspect it is one thing, it is probably more likely a combination of about 4 things. The crush is important but there are LHBS that crush nicely, but most don't from what I know. Hitting your temps is very important too and that includes your mashout temp and make sure to stir like a madman when you mash in to make sure everything is getting soaked. Sparge slowly.... the list goes on and on but you have probably heard all of this. I have my primitive system dialed in and always get between 82 and 85% efficiency and am happy with that, but I do my own crushing and keep consistent with my procedures.

I'm not new at all grain, just my system is. I went from using the Gott 10 gallon cooler as a Mash Tun, but have since upgraded to sanke kegs for the sparge, mash, and boil. I'm still tweaking things a bit. And my LHBS is definately one that isn't good at crushing.
