EU Laws - Analysis

Question 1

What are the mandatory analysis parameters for wine compliance in the EU?

Answer 1

Alcohol content
Residual sugar
Total and free sulfur dioxide (SO₂: <150 mg/L for red wines, <200 mg/L for white and rosé wines)
pH and acidity levels (total acidity >4.5 g/L as tartaric acid)
Volatile acidity (<1.2 g/L for red wines, <1.08 g/L for white wines)
Stability tests (if required).

Question 2

As a QC manager, what should you focus on for chemical analysis during a bottling audit?

Answer 2

Verify compliance with alcohol content.
SO₂ (free SO₂ <50 mg/L).
pH and acidity (>4.5 g/L).
Residual sugar (e.g., dry wines <4 g/L).
Ensure analysis meets EU regulatory thresholds.

Question 3

Why is traceability critical in wine production and bottling?

Answer 3

Enables quick identification and recall of affected batches.
