Mangrove Jack's Wine Yeast - AW4
$4.60

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.

Mangrove Jack's Wine Yeast - BV7
$4.60

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.

Mangrove Jack's Wine Yeast - CL23
$4.60

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.

Mangrove Jack's Wine Yeast - CR51
$4.60

Perfect for light, fruity red wines for early consumption

CR51 will enhance ripe berry fruit flavours in light and fruity red wines and introduce a velvet texture perfect for Valpolicella and especially for Beaujolais style wines. This strain has an almost unique ability to confer a smooth even ‘silky’ quality to the wine, perfect for early consumption young reds.

Mangrove Jack's Wine Yeast - CY17
$4.60

For sweet white/blush and dessert wines. Produces high levels of desirable congeners during fermentation including aromatic thiols, imparting rich fruity aromatics, full body and ‘tropical’ flavor characteristics. CY17 is also noted for high glycerol formation, further enhancing sweetness. 

This is a slow fermenter compared to all other strains in the Mangrove Jack's range, typically taking up to 21 days to ferment table wines and up to 35 days for dessert wines.

Mangrove Jack's Wine Yeast - MA33
$4.60

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.

Mangrove Jack's Wine Yeast - R56
$4.60

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.

Mangrove Jack's Wine Yeast - SN9
$4.60

Very good all round strain, best choice for high alcohol and fortified wines but also excellent for most country wines, sweet sparkling wines and ciders.

If you only had one wine yeast strain, this would be the strain because whilst being relatively neutral in character SN9 does introduce excellent weight and structure no matter the must or fruit and produces a congener profile that always compliments the wine.

SN9 is particularly good when fermenting flower or low fruit recipes which often lack vinosity, weight and depth.

10642

Mangrove Jack's Wine Yeast - VR21
$4.60

Exceptional strain for full fruit varietal and country red wines promoting good structure, balance and colour.

The majority of yeast strains strip out fruit flavour and colour from the must, not so with VR21 which is particularly noted for preserving and retaining the natural fruit characteristics of the grape / country fruit and enhancing palate length.
