Still, a 1/2 teaspoon of gelatin (hydrated in 1/2 cup of water then boiled and cooled) knocked out at least half of the astringency, maybe more, even though a lot of it settled out without contacting all of the contents. I also added it to my Scottish ale which normally is crystal clear but this time had chill haze. Used 1/4 teaspoon and it worked like a charm.
Just wondering what type of gelatin that you used and where you got it???

Exactly. Sparge until runnings are down to 1.008 or so at which point you have about as much sugar as you are going to get without tannin extraction. Then top off with water to get your pre-boil volume. I would have to check a lot of history of my recipes, but I don't think I ever made a beer under 1.050 before, so I have always collected 6.5 gallons of wort without going under 1.008 final runnings.

I bought the gelatin finings you find in most homebrew stores - I think it is LD Carlson.

Haven't looked at this thread in a while, so I thought I'd chime in.

Jesse, you can get gelatin finings from your HBS or online. Northern Brewer sells it for about $1.10 per oz. As Beercat said, you only need about 1/2 a teaspoon for 5 gallons, so the 1 ounce bottle could last you for a few batches.

Beercat, glad it worked out! I agree that stirring it in might help, but I haven't tried it. I didn't stir either, and I'm starting to notice that some of my bottles seem more mellow than others. Mind you, that could also be due to several other factors.

I buy gelatin by the pound from Midwest.

But in a pinch, unflavored gelatin packets from the grocery store is the same stuff.
