pH
harvest - for optimum ripeness (w/ TA, Brix)
pre-frermentation - to optimize yeast fermentation
pre-MLF - to optimize growth of desired MLF bacteria
post-MLF - to determine proper sulfite additions
maturation - to determine proper sulfite additions
bottling - to prevent premature/excess aging


Titratable Acidity
harvest - for optimum ripeness (w/ pH, Brix)
post-fermentation (whites)- to adjust for proper taste balance
post-MLF (reds) - to adjust for proper taste balance
maturation - to correct for acidity losses during aging
bottling - to ensure taste balance (don't bottle right after adjustment)


Residual Sugar
fermentation - to determine completion of dry wine fermentations


L-Lactic Acid
MLF - to confirm the start of MLF


Malic Acid
pre-MLF - to estimate loss of acidity during MLF (w/ dilution of sample)
MLF - to monitor for stuck MLF
MLF - to determine completion and time to add sulfite


Free SO2
to confirm proper addition during cold soak (whites)
post-fermentation (whites) - to confirm proper addtion
post MLF (reds) - to confirm proper addition (>50% becomes bound)
maturation - to determine need for replacement due to oxidation, binding


D-Lactic Acid
must - to determine excess contamination
fermentation - to check for growth of unwanted lactic bacteria,
ooooespecially with sugar present and a stuck fermentation
MLF - to check for growth of unwanted lactic bacteria
maturation - to check for growth of unwanted lactic bacteria
