Default Man that's bitter...astringent?

Ok, so I attempted my first AG 2 weeks ago. I picked a simple Nut Brown AG kit from my favorite HBS. Had some issues with a stuck sparge and ended up draining the sparge water at a trickle over the course of about an hour.

So I tasted the wort before adding yeast after taking my gravity and man was it bitter. I thought the low OG of 1.034 (instead of the 1.040 it was supposed to hit) was the culprit. But, after transferring to the secondary this weekend, I am now wondering if I really leached the heck out of those husks and got some tannins. I know the astringent taste is described as sucking on a teabag, but I'm still not sure if it is more hops bitterness or tannins. Can anyone describe the astringent taste in more detail than the teabag or maybe just based upon my description of the sparge problem, is this most likely the bitter culprit?

Thanks!
Greg

Astringent taste somewhat bitter but I think it is best described as a much puckering bitterness, makes your mouth feel really dry.

Give us a run down of your recipe and process. Did you keep temp records?

The bitterness in my green beer is due to the...green beer effect. The hops are still powerful strong and the flavors are not mellowed yet.

Let's see what you brewed and how and that'll help.

Note that I often do slow sparges but that alone (in my brewery) doesn't drive up the bitterness.

Like Beerrific said, if you puckered up and crossed your eyes...that's astringency.

If not...that's just a good hoppy beer.

No prob wort is always more bitter that the finished beer. Odds are it will be fine.

It is curious you would get a stuck sparge on what I assume an all barley beer. Was the grain crush too fine? That can contribute to bitterness.

Unfermented wort is wicked bitter, you'll be fine. Astringency isn't a flavor its a mouthfeel, dry feeling on the back of your tongue.

Your tongue is more sensitive to astringent flavours on the sides, and more sensitive to bitterness near the back.
So when you taste it, do you 'feel' the flavor on the sides, or closer to the back of the tongue.

I second that. Imho, the wort just after the boil is not very appealing at all.

Any chance that you used too much hops or boiled them for too long. I didn't double check my last all-grain stout recipe and it was very very bitter. I went online to a recipe and the IBU's where around 90! Oops..

That extreme bitterness has chilled out a little bit, but it sounds similar to what you are describing.

Wow, thanks for all the replies folks! I used an AG kit from NB since i wanted to play it safe on my first AG. I used the Nut Brown kit here: http://www.northernbrewer.com/docs/kis-html/1033.html

Single infusion mash, started around 153 and then batch sparged at about 168. Hard to say how much sparge water got used. I let it slowly leak out of the cooler for about an hour before I finally gave up and just added the extra gallon or two of water to the brewpot to make 6. Then added hops and boiled for an hour.

Maybe I am just used to the extract kits where the wort tastes really sweet and the bitterness doesn't show itself until after the yeast does it's work. Another week or so in the secondary and we'll see!

Greg
