Astringent taste a few days after tapping
« on: April 30, 2011, 08:39:54 pm »
I kegged an IPA and the first two days it tasted great.  Then, it started tasting astringent I think.  I can describe it as a lingering bitter aftertaste and almost dry.  I know IPA's are suppose to be bitter, but this is just different.  What really has me stumped is that it tasted great the first two days and now it's not good.  I dry hopped with Columbus and the aroma is considerably down than before.  Any suggestions as to what happened? :-\

Might be oxidation.  It can give a harsh bitterness. It can also dull aromas and flavors.

It's not becoming over carbed.  I was also thinking that it could be oxidation, but how?

I'd suspect it could have been introduced during either the dry hopping process or the kegging process.  Did you purge the keg with CO2 before filling it?  Did you blow CO2 on top of the beer during the dry hopping?  Did you check that your dry hops weren't oxidized before you used them?  Those are the few that come to mind as most likely.

Thanks Gordon,  I think there is a strong possibility that I might have forgot to purge the keg before I filled it.  Maybe I should make a check list on my fridge.

Tailoring a checklist to your specific process can help considerably.  All you have to do is save one batch and it's worthwhile.  There are a lot of steps and it's easy to get distracted or forget small parts of the process.
