Tried this and it worked well.
I have found that the wine you start with has to have been racked and clarified to some extent say with bentonite, so somewhat cloudy is an acceptable starting point.
I did not find that 1 tablespoon is enough, but rather 2 tblsn works much better. Boil 1 cup of water and add the 2 tblspn, boil for another 5 minutes, then slowly pour it into 5 gallons of wine while stirring.
Then let it set for a week minimum; my experience is that it clarifies it to completely clear, ready for bottling - add a camden tablet per gallon, additional sweetening and flavoring, and seal it up for later consumption.

I have always used bentonite in thr beginning of my mead ferments with good result. I thought i would try this product to get a little more polish. It was amazing the difference. This last brew (mead) i cut back by half the amount of bentonite and was surprised that the clarity remained the same

works as described, will use again

First time ive ever used it, was amazed at how well it worked

As always a good product at a good price.
