Tartaric acid to add: grams per volume
Tom has changed the tartaric addition rate
to 1.5 (1.49g) g/gallon will increase the acid by .1%. The
approximate kitchen measure is ~1/4 teaspoon will raise one gallon TA it
by .1% This is double of what we have figured in the
past. Always err on the
side of caution. calculate, reduce calculated dose by half, add,
retest. SO I have
discarded out entire chart we use to have here for tartaric acid
addition. Sorry.
Basic info from long ago, on our tartaric acid label: 1.9 grams (1/4 teaspoon) of tartaric acid per gallon will raise the acid approximately .05%.
The recommendation of less acid blend is based on the use of citric
acid in these blends. Citric acid will not be reduced by cold stabilization in case of overdose. The
competition currently indicates a rate of 4.1 grams/gallon to increase the
TA by .1% (Oct 2010)
WHY if TA is % tartaric acid, wouldn't 1
gram raise 1 gallon 1%. Is this too simple?
