The test is staight forward, take a sample of the wort and grains placed on a white saucer, add a drop of iodine, if it changes to blue starch is present, if no change sugars are present.
The test does not differntiate between the different sugars.
I do this as a matter of course, if the temperature and length of time is correct for the mash starch end point should be reached within the mash time period.
