Adjusting Specific Gravity
Specific Gravity Adjustments
To increase the specific gravity of juice: Add table sugar to increase the gravity. To calculate the amount needed, take an initial gravity reading, then subtract that from the specific gravity you wish to begin with. The difference will determine approximately how much sugar to add (use column on right).
Example: If your current gravity is 1.075 (24.5 oz. sugar per gal), and the desired gravity is 1.095 (31.0 oz. sugar per gal) then [ 31.0 – 24.5 = 6.5 oz.] So 6.5 oz. of sugar per gallon that must be added to bring the gravity up to 1.095
To reduce the specific gravity (if sugar level is too high): 2 quarts of water will decrease a 5 gallon must approximately by 0.010
