Default Mash Efficiency

Is it possible to get 86.5% mash efficiency?

If I did my math right... thats what I came up with for my first AG.

Sure its possible. I just use Tastybrews calculator and my first AG I got 78.8% efficiency. However, I lost 10 points on my second one ~69% efficiency.

Not a single thing wrong with ~77%. Especially your first go round. I would be happy with 77% every time.

Thanks

It was extremely fun to do... I am definitely hooked on this hobby now. The only thing bothering me is the water in my airlock keep getting sucked into the carboy... Im afraid the wort's going to get contaminated.

How can I keep that from happening?

Sounds like you are filling the airlock up to much- past the center cylinder. Try just filling it 1/3 but enough where the bottom of the "air cap" is submerged. Also try using cheap vodka instead of water. It will stay sterilized, keep insects from getting in during the summer, and if any does get sucked into your carboy... you see where that is going.

Filling it up just to the line... I have it in a temp controlled freezer. You think it might be a difference in temp between the freezer and the carboy?

Yep, exactly---the thermal delta causes the liquid to get sucked into the carboy.
