Adding acid

[Rogerm]

Am making some merlot from grapes my ph is 3.8 I know I should add some acid but I have not tested TA yet to find out how much to add.
Does anyone know if I can test TA and add acid during fermentation ?

The rule of thumb for tartaric acid addition is 1 tsp to reduce the ph by 0.1 per gallon

Is that to drop ph or TA by .1

all additions should be before fermentation. Add 10 grams of tartaric acid to one gallon of water. Add the acidified water a portion at a time to must stirring all the time and monitoring the ph. repeat if necessary to get ph to 3.4

The PH will drop further .1~.2 after fermentation. You may not need add more. I wouldn't do it if I were you.
