Main functions
  • Use in enrichment: 1 kg of MCRS (Volume = 0.66 litres) develops 0.5943 litres of alcohol → 1.68 kg of MCRS increase 100 litres of wine by 1 degree of alcohol
  • Use in fermentation: To raise 1 atm (~1L CO2/L) 1 litre of wine, 4 g of MCRS are needed


Naturalia sugars, available in different versions and certifications, are intended for both the food and wine sectors (only if produced from wine grapes and therefore derived from must and not juice).

Wine products can be certified organic according to EU regulations, and can also be used as organic ingredients in the food industry, as expressly stated in the MIPAAF circular of 6 June 2012.
