Default Tannins in a turbid mash

After learning to do a turbid mash for a lambic, I decided to try using it for my standard Witbier recipe. After giving the beer a number of weeks in the secondary, I transfered to my keg and carbed it, and just tried it out. There is a definite bitterness and mild astringency to the beer that I haven't tasted before and that does not seem quite like the usual effects of my hops, so I am assuming these are tannins from the mash. Anyone have some thoughts on whether these tend to ease off at all in a matter of extra weeks or if this is a multi-year aging requirement (like in wine)?

Just skip the classic turbid mash and dump a spoon or two of wheat flour at boil.

Is that an effect of tannins or of the unconverted starch from the turbid mash?

I've had samples of young turbid mashed beers that didn't have much of a tannic bite, but the really hot sparge certainly could cause problems. What was your schedule? I believe gelatin is supposed to help pull out tannins, although it will also kill your haze.

Gelatin eh? I wonder if Islinglass would do something similar?

I didn't do a ridiculously hot sparge for this since...just around 170-175F, if memory serves.

I think I have the same issue going on with my last two beers. IPAs. Did you ever get it nailed down. I took mine to a pro brewer and he said "It's pretty good but has just some slight astringency and I don't know what it is. I don't know what I changed. Its upsetting.

In an IPA you could be getting astringency from your hops, what was your recipe/procedure?
