Refrigeration installations for wine storage

When processing and storing wine and grape must, stable temperatures are of particular importance to preserve the quality of the product. It is necessary to install an installation capable of cooling and heating the product, which is achieved with an air conditioning system, a chiller type, operating with a refrigerant, most often glycol is used as the coolant in the piping. Main temperature ranges during the different stages of wine processing: When fermenting red wine, the optimal temperature is 22–28 °C. When storing red wine, the most suitable temperature is 12–16 °C. When fermenting white wine, lower temperatures are used to preserve aromas and freshness - the optimal range is -12–18 °C. When storing white wine, the required temperature is slightly lower than that for red - 8–12 °C (the ideal is around 10 °C). When stabilizing red wine and white wine, the temperature depends on the type of stabilization being carried out, most often referring to cold stabilization at a temperature of -2 to +2 °C for 7–20 days without the wine freezing.
