Even worth bottling?

Couple weeks ago I brewed a black IPA from extract. While steeping the grains I left the kitchen, only to return and find my temp was around 190 F....Doh! I pulled the grain bag out immediately, and forged on. When I transferred to secondary last week I took a taste and I found it to be astringent. Not roasty bitter, or hoppy bitter, but I think astringent would be the word. Is there any hope of time lessening this flavor, or am I screwed this time? Thanks in advance for any opinions!

Don't dump it!!!! Give it time and chances are it will improve. Knowing what happened with the grains, you're probably going to try to find a problem with it, but rdwhahb.
