I have brewed about 12 batches so far. I have had some great brews, but a lot of them have not turned out so well. In all of the lighter and not so hoppy brews I have done (2 blondes, lager, hefe, & amber), I get what I would call an astringency. It makes your mouth cringe and is harsh. I am really becoming aware of this as my palate gets more refined.
A pro brewer noticed it in a stout I made, but was much harder to pick up on because of the style.
Aroma is great. At first the off flavor doesn't come on as much, then it really hits towards the end.
I mini-mash. I have done one all extract hefe and the same off flavor was there, so that makes it hard for me to think it's my mash. I use the same water every time, spring water from the dollar store. I have checked PH in the mash before and I believe it was pretty close to 5.3 or so. My sanitation is great
Any ideas? What to try next?
please help, my brews are not near what they can be.
