Sure enough the minimum dose was not enough. The equivalent dose to that supplied with kits would be 'heavy', 3ml per gallon of each part. Because Clear It uses gelatine, the tiny amount of tannin I added will be stripped out. Only 1 of the recipes I read included it, at the rate of 1/4 teaspoon (1.25 g) per gallon. However, it took a rounded teaspoon of the powder to even register 1 g on the digital scales. I will add this after clearing, to give it a bit more bite and a little colour. I just checked the best before date, sept 2012. So I mixed 1/2 a teaspoonful with a wineglass of water and tasted it. This is a massive concentration, but the effect on the palate was little more than strong tea. So I will have to get fresh stock.
