Wine Stabilisation

VSHCE housing_wA number of factors influence the character and appeal of wine during its journey from the fermentation tank to the bottle, but in order to produce stable wine which protects and develops flavour once packaged, the presence of spoilage organisms has to be reduced or eliminated completely.

Typical spoilage organisms in bottled wine are species capable of growing in low pH and anaerobic conditions, for example, lactic acid bacteria and fermenting yeasts such as Brettanomyces bruxellensis.  Spoilage organisms can ruin wine by causing off flavours and haze or cloudiness, with contamination from strongly fermenting yeasts causing bottle explosions.  Depending upon the type of the wine and the processes used during its production, the threat of microbial spoilage will vary.  Relatively young wine with low tannin levels and high residual sugar may be subject to spoilage from low numbers of yeast / bacteria.  Mature wines with high alcohol, tannin and low nutrients may be slightly more resistant, however, threats from microbial contamination still exist.

For red wines, membrane filtration down to 0.65µm is typically adequate to eliminate spoilage organisms, however, for white wines 0.45µm is typically used.  Filtration with a tighter membrane than is necessary will cause the filter to block quicker, resulting in an uneconomical process so care must be taken to use the correct grade for the conditions.

Parker domnick hunter’s BEVPOR wine filters utilize an inert PES membrane which has been designed to protect the flavour and character of wine by providing validated retention to typical spoilage organisms, without impacting upon taste or colour profiles.
