Pre-Bottling Stability Analysis

An essential stage in preparation for bottling, stability analysis requires specific tests methodologies. Our research team has developed different tests to measure wine stability to ensure the effectiveness of a stabilisation treatment. These measures are fundamental to quality control and to avoid post-bottling disorders.

AnalysisMethod
Protein stability Heat test
Bentonite dosage Heat test after bentonite addition
Fining trial -
Tartaric degree of instability (DIT) Conductivity (STABILAB®, patent Eurodia/INRA)
Critic index of tartaric stability (ISTC50) Conductivity (STABILAB®, patent Eurodia/INRA)
Crystallization test 6 days / -4°C 
Colouring matter stability Cold test (48 h / 4°C)

*Ten years of fundamental and applied research has led to the development of MANNOSTAB®, a natural product that inhibits potassium bitartrate crystallization (www.laffort.com).
Its use requires specific tests to be conducted.
