Fermentation media must satisfy all the nutritional requirements of the microorganisms and fulfill the technical objectives of the process (1). There are several stages where media are required in a fermentation process; inoculum (starter culture)‚ propagation steps‚ pilot-scale fermentations and the main production fermentations (2).

Although some winemakers avoid this practice claiming that it can cause flavour and colour loss‚ membrane filters with 0.45μm pore sizes can remove all the bacteria and yeast. This is the most effective strategy to prevent spoilage before bottling without addition of SO2. Especially for no-SO2 wine‚ membrane filter integrity is imperative‚ thus pressure hold test is strongly recommended. In addition‚ heat can be hired here
