Tincture of Iodine - 30ml [365]
£5.50
Tinture of iodine is used for measuring the amount of starch remaining in a cooled wort. A few drops are added to a small sample of wort, if any starch is present the solution will turn blue almost immediately. If no colour change occurs the wort is free of start and will not impart a starch haze to the finished beer.
