Stability problems in wine

Wine instability is a frequent problem across the industry, resulting in product recalls and monetary losses.  These issues can take many forms - including heat, cold, and collidal instabilities - resulting in a product that is not acceptable to consumers.

Join specialists from ETS as they focus on the causes of these instabilities, emphasizing heat and cold instability.  The presentation will cover:

  • The chemistry underlying heat-induced haze and bentonite fining
  • Methods of determining heat stability and interpretation of test results
  • Cold stability: the science behind the formation of potassium bitartrate
  • Choosing the right cold stability methods, including conductivity and concentration product
  • Case studies on colloidal instabilities - interactions between polysaccharides, proteins, and phenolic compounds
