Saccharomyces Cerevisiae – The ‘only strain’ for Germanic aromatic white wines.
AW4 is noted for developing powerfully fragrant, full spice aromatic wines and is a perfect match for Gewurztraminer and also recommended for Sauvignon and Semillon where the Oenologist requires a positive aromatic esters contribution from the yeast.
AW4 is a good fermenter across the range 14 to 30ºC (57 -86ºF), low foam formation and medium to high glycerol. It will ferment up to 14.5% abv. ethanol providing the temperature is held within the 20 – 25ºC (68 -77ºF) range and the pH is above 3.0
This strain is known for it’s exceptional reliability and it’s ability to consistently deliver fresh, clean, crisp and robust ciders. It is a very low foaming strain that will ferment between 10 – 35°C, adhering to the ideal fermentation for cider; measured and steady. The flavour characteristics confered by this strain are neutral and clean meaning that the natural flavour of the fruit will be the prominant taste on the palate, guaranteeing a satisfying, well balanced cider. Overall, a classic cider yeast that will ferment to dryness with a delicious, powerful and refreshing fruity finish, perfect for making your own traditional European cider.

Saccharomyces Cerevisiae – Ideally suited for rich, full bodied red wines with exceptional flavour complexity.
Noted for exceptional depth and flavour complexity, R56 exhibits complex aromatics during fermentation conferring an old world quality which one might only expect from natural flora multiple strain fermentations.
Unusually for complex aromatic strains, R56 still respects the varietal character of the fruit and confers good structure and balance. R56 is also a high glycerol producing strain.
R56 is a medium rate fermenter with optimal temperature between 22 to 30ºC (72 -86ºF) which will ferment to 13.5% abv. ethanol.
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. Will ferment up to 14% ABV. ethanol providing the pH is above 3.2
