Default Tannin extraction

Just a question. I don't mash out. Today I did a 90 minute 156* infusion. The runnings got down to 1.0084 give or take. The mash temp never got over 160*f. Did I extract tannin from the husk? I usually stop at 1.010. I hit the target gravity right on and efficiency was the usual 83%

I made an English bitter.
Here is the grain bill if it helps

Bierds (beards) Maris Otter 12.5 lbs
English crystal 40L 1 lb
Carapils 1 lb.


OG 1.041

Crush was right on too, Maltmill tm set at factory settings, I run the grain through twice.

22 Qts strike water, 11 gal batch.

Fly sparge with 170*

David

Taste everything as you brew. I recently brewed with a neighbor and was amazed that he did not taste anything at any point in the process. At some point in your brewing education you will be able to tell by taste alone how your brewing is going. Just like a great chef or baker!

It only tasted mildly sweet.

Thanks for the response.

It's doubtful you extracted enough tannins to notice, but it's largely dependent on your sparge water pH. The higher the water pH, the higher the risk of tannin extraction in a continuous sparge.
