I found an old fact sheet on Cryofine. It's manufactured by James Vickers Ltd. in the UK. Phone#01283563268. It says all you have to do is mix the cryofine into cold water or beer (15-20C) at a rate of 5-10 g/L. Mix it in a powerful mixer. Mix for two minutes every 10 minutes for 30 minutes and add to beer preferably inline. It gives a rate of 1.2-2.5 grams per hl for optimum clarity. You will just have to experiment with small amounts of beer first. If you want a copy of the entire sheet give me a fax and I'll send it to you or call the UK. Hope this helps. By the way it says there is a 7 day shelf life once you hydrate it.
