Starch Testing Solution
Protein Test Solution£9.50
Add 5ml of this Indicator Solution to 5ml of wine or beer and shake well:-
Brown colouration shows no protein is present.
Green colouration indicates that some protein is present.
Blue Colouration shows a lot of protein is present.
With dark liquids the formation of flakes shows that protein is present.
Starch Test Solution (Tincture of Iodine)£4.95
To check that starch conversion is complete, remove 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.
