A quick and easy way to check your sugar levels. Pipet 1/2 ml into test tube then add pill and in a few second you have your result.
Store at room temperatures between 59 - 86 degrees Fahrenheit and out of direct sunlight.
Shelf Life: Declines with exposed air.
Discard when tablets have bright blue spots.
A. FOR WINES WITH LESS THAN 1% RESIDUAL SUGAR – ‘the 10 drop method':
Place 10 drops (0.5 ml) of wine in the test tube. Hold the test tube over a piece of unlined white paper for better visibility.
Drop one reagent tablet in the test tube. Watch the reaction while shaking the tube to make sure the color change does not pass through the orange color and turn slightly brownish. If this occurs you have more than 1% residual and you will need to follow the secondary procedure, the 2 drop method in paragraph B below.
If the color change does not go to or pass through orange, wait until the boiling reaction is finished, then match the color to the color chart for the 2 Drop Method on the Clinitest instructions. Read the amount of residual sugar from the below chart for the 10 drop method.
If you get a color that appears to be between any two of the color slabs you can assume an intermediate value, but be certain that the wine never passed through to the orange color and then to a brown color.
B. FOR WINES CONTAINING FROM 1 TO 5% RESIDUAL SUGAR – ‘the 2 drop method':
1) Place 2 drops (0.1 ml) of wine into the sample tube and add 8 drops (0.4 ml) of water.
2) Drop one reagent tablet into the tube and watch the reaction to be certain it does not go all the way to the orange color. If it does, you have more than 5% residual sugar and should follow the procedure paragraph C for the one drop method.
3) If the color change does not go to or pass through orange, wait until the boiling reaction is finished, then match the color to the color chart for the 2 Drop Method on the Clinitest instructions. Read the amount of residual sugar from the above chart for 2 drop method.
C. FOR WINES CONTAINING MORE THAN 5% RESIDUAL SUGAR – ‘the 1 drop method':
Add 1 drop (0.05 ml) of wine and 9 drops (0.45 ml) of water to the test tube and proceed as above. If you pass through the orange color and go to a brown you have more than 10% residual sugar and cannot get a measurement with this test.
If the color change does not pass through orange, wait until the boiling reaction is finished, then match the color to the color chart for the 2 Drop Method on the Clinitest instructions. Read the amount of residual sugar from the above chart for 1 drop method.
Be aware that your accuracy is greatly reduced when using a single drop of wine for your test. The result would only indicate an approximate range.
