 Dietary Supplements 1This dietary supplement is made with a dry herb.Step 1.  Item 9 Calculation – all of the eligible alcohol comes from 190 proof ethanol.  Calculate the volume of absolute alcohol:95 fl oz. × 0.95 = 90.25 fl oz. of absolute alcoholNext, divide by the yield. Low end of yield range –90.25 fl oz. ÷ 104.2 fl oz. = 0.8661 or 86.61%High end of yield range –90.25 fl oz. ÷ 117.8 fl oz. = 0.7661 or 76.61% Click on the image to enlarge

Step 2.  Item 10 Calculation – This should be done in a similar way as extracts are calculated.

The volume of absolute alcohol is calculated the same way as in step 1.  The volume of absolute alcohol is then divided by the starting menstruum (volume of ethanol, water and other dissolved components).

In this example, the starting menstruum is just ethanol and water.

95 fl oz. + 35 fl oz. = 130 fl oz.

90.25 fl oz. ÷ 130 fl oz. = 0.6942 or 69.42%

The tolerance used for dietary supplements for item 10 is always +/- 5.

Note:  The alcohol content of the finished product cannot be less than zero or higher than the theoretical alcohol content (e.g. if 190 proof alcohol is used, the alcohol content of the product cannot be greater than 95%).
