Other claims from this paper (6)
- Observation Samples with no detectable AAB in musts or wine had volatile acidity within the acceptable limits.
- Observation The Rara Neagra grape sample had the highest volatile acidity (2.11 g/L), exceeding the maximum acceptable limit for red wines of 1.2 g/L.
- Observation A. pasteurianus was more common than A. aceti in musts and wines.
- Observation Samples positive for AAB with low amounts in wine (Cq value > 35) did not have volatile acidity above the acceptable level.
- Observation Samples that were negative for AAB in wine but positive in must had volatile acidity close to the acceptable limit.
- Method / resource PCR diagnostics are useful for predicting the risk of wine spoilage by AAB.
