Harris Starch Test Reagent 30ml

A reagent to test wines and beers for the presence of starch.

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.
