My third batch of beer is undrinkable. I think the taste is better described as astringent rather than bitter. And I think the cause may be that I squeezed the grain steeping bag to save time (do not to that on two previous batches of acceptable beer).

Questions:
- If that's it, will the astringency mellow with age in the bottle?
- I live in a hot climate. Could this be caused by fermenting in a closet that is frequently more than 80 degrees?
- I don't think I had a sanitation problem, but if I did would I be getting this kind of taste? Or something else.

I'm sure this is not your issue. I, and many others, have squeezed many a grain bag and made delicious beer.

There's really no way to tell except trying. I imagine it will improve with age, but it may never get good.

This will cause all manner of off flavors. This is most likely your culprit. You don't really want to ferment in an ambient space above 65F or so, to keep the temperature of the fermenting beer (which creates its own heat) below 70F. Some yeasts even get nasty in the high 60s.

I agree that sanitation is probably not your issue, unless you could describe the flavor as sour. Most infections are taste noticeably "spoiled".

Not shure if astringency is the word you mean,but what yeast did you use and yeah usually 80 is too high when actuall fermentation can generate 5-10 deg more during fermentation. Ageing could improve it but may take some time and may never reallly mellow enough. As far as astringency I would think your water could have something to do with that. Do you mean estery and fruity? Squeezing the bag is not a problem unless your water ph is waaay off.
Harshness usually improves with age. Ive had one harsh brew which i considered astringent, and i think it was from using whole torrefied pastry wheat berries. That completly mellowed out. And turned into a well liked beer.
Almost sounds like a mineral problem with your water. Too much of the right minerals can effect your brew.

I doubt squeezing the grain bag is the issue. As noted by others, fermenting in an ambient air temp of 80F isn't going to lead to a good tasting beer.

I agree with KISS Brew! It's almost a guarantee to be your fermentation temp. The off flavors that come from that usually don't go away. It might mellow a little, but you're likely stuck with it..

Temp is for sure a problem. If you were at 80 then the wort was more like 85 or greater. A wet towel and fan will lower the temps 5 to 8 degrees.

Squeezing the bag is a big big mo no and would lead to so nasty tannins. Be gentle but not anal.

And no sadly if it's REAL bad it won't go away.

These days most people that do BIAB have concluded that this just isn't true. I've sqeezed my BIAB bag between two boards with clamps, and made some really tasty brews this way. You can squeeze the grain bag all you want. It won't extract tannins unless the pH is out of range...

I wouldn't describe green apple as astringent. Green apple usually refers to "green" beer in general.

I do agree that the OP should wait it out, but IME most astringent flavors associated with malt in-balance, high ferm temps, or tannins doesn't go away.

Only time can tell...

*shrug* I had a belgian strong golden that was a little underpitched that had a flavor similar to chewing on apple peels until it had aged longer than a few weeks.
