Vintners Harvest Yeast - MA33 - Saccharomyces Cerevisiae

Acid reducing strain excellent for fruity white & blush country wines especially where residual sugars are desired. MA33 has the ability to metabolize between 30 and 35% of malic acid making this strain the perfect choice for country fruits which are naturally high in acid. Reducing malic acid will soften the wine and

give a vin nouveau character for early consumption with a balanced palate. MA33 is also noted for its production of fruity esters and fusel oils conferring fresh fruity character to the wine. There is an increased

chance of Malolactic fermentation by lactic acid bacteria following MA33 fermentation. MA33 is a killer-sensitive strain. It is a good fermenter between 18 and 27oC (64 -80oF), with a rapid onset to fermentation although can exhibit a slow late fermentation profile and may require aeration after 10 – 12 days fermentation. Will ferment up to 14% abv. ethanol providing the pH is above 3.2.
