MA33 Vintner's Harvest


Species : Wine
Fermentation Temp Range (°F) : 64-80
Apparent Attenuation Range (%) : n/a
Flocculation : Medium
Alcohol Tolerance : 14%

Pitching/Fermentation : Vintner's Harvest Yeast - MA 33 Acid reducing strain excellent for fruity white and blush country wines, especially where residual sugars are desired. MA 33 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.

Notes : There is an increased chance of malolactic fermentation by lactic acid bacteria following MA33 fermentation. MA 33 is a killer-sensitive strain. It is a good fermenter between 18 and 27C (64 -80F), with a rapid onset to fermentation, although it can exhibit a slow late fermentation profile and may require aeration after 10 – 12 days of fermentation. Will ferment up to 14% abv providing the pH is above 3.2.

Best Styles : Blush, Fruit Wine, Fruity Whites
