Tincture of Iodine 30ml
Starch Test Reagent Harris
For Beer:-
Use this to check that starch conversion is complete, by removing a few grains from the mash, place them on a white surface and add 2-3 drops of the Iodine. If the Iodine turns a dark blue to black in colour this shows that conversion is incomplete and contine to mash.
For Wine:-
Add 2ml of Starch Test Reagent to a test tube, using a pipette. Then add 6ml of wort or wine. Secure the test tube cap and shake for a few seconds. If the solution remains an amber or brown colour then starch is not present. If the colour changes to a deep red or blue/black then starch is present and the resulting drink may not be clear
