Ideal for crisp, fresh dry white/blush and all sparkling wines. Also the best strain for high alcohol tolerance. CL23 produces very low levels of fusel oils and other congener compounds during fermentation and so does not contribute much to wine flavour or aroma and can therefore be considered to be a particularly neutral / clean fermenter.
However CL23 does contribute significantly to the wines structure and ferments out sugars completely allowing for the driest of wines to be made. CL23 is noted for its robustness, being able to ferment to 18% ABV. Ethanol, tolerate high free SO2 and high levels of other stress factors such as organic acids, incorrect temperature and pH making CL23 the strain of choice for high alcohol wines or where uncertain recipes are employed and fermentation reliability is a key factor or where low temperature fermentation down to 80ºC (46ºF) is required.

Saccharomyces Cerevisiae – Ideal for full bodied, full flavoured dry and sweet white wines.
BV7 will both preserve and enhance the grape variety and terroir, promoting excellent flavour complexity, good wine structure and balance but especially full aromatic flavour. To appreciate the impact of BV7, split a chardonnay must, fermenting half with CL23 and the remainder with BV7 – you will be amazed at the impact of the yeast strain upon fruit concentration.
BV7 produces a wide range of low level beneficial congeners such as higher alcohols and esters and high glycerol promoting full body and structure to the wine and contributing significantly to mouth-feel, wine texture and palate intensity.
Avoid fermenting above 13% abv. ethanol, BV7 is not particularly ethanol tolerant. Acceptable temperature range is 15 to 30ºC (59 -86ºF) but ferment below 22ºC (72ºF) for maximum flavour development.
Youngs Ale Yeast is a customary example of a traditional top fermenting English Ale yeast and is used throughout the country in commercial breweries as well as by home brewers. The pure single strain culture has several outstanding characteristics such as it’s high temperature tolerance, high alcohol tolerance, relatively low risk of bacterial contamination and outstanding sedimentation characteristics, making it a consistently popular option, delivering reliable top quality Ale’s. You can expect a full bodied, fruity Ale with a hoppy, estery nose and palate. When using this yeast you can look forward to a high final gravity that delivers additional body, weight and a fuller flavour to competitor yeasts. Young’s Ale yeast can be sensitive to variations in fermentation temperature but where constant temperature is used it is a forceful strain with very strong fermentation and moderate attenuation properties.

Rehydration
During yeast manufacture, special processs are employed to promote very high leveles of the natural compound – Trehalose within the yeast.
Trehalose is a natural sugar produced within the yeast cells to protect itself during prolonged storage and stress conditions.
The very high levels of trehalose acheieved also remove the need for re-hydration before adding to must or wort – there is now no advantage in doing this even for high alcohol wines.
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.

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
