SN9 Vintner's Harvest/Mangrove Jack


Species : Wine
Fermentation Temp Range (°F) : 68-75
Apparent Attenuation Range (%) : n/a
Flocculation : Medium
Alcohol Tolerance : 18%

Pitching/Fermentation : Excellent all-purpose strain, good for high alcohol and fortified wines as well as country wines, sweet sparkling wines, and ciders. If you could only use one wine yeast strain, this would be it. While relatively neutral in character, SN9 does introduce excellent weight and structure no matter the must or fruit and produces a congener profile that always complements the wine. Particularly good when fermenting flower or low fruit recipes which often lack vinosity, weight and depth.

Notes : Like CL23, SN9 can ferment up to 18% abv, and is noted for its robustness, able to tolerate high levels of alcohol and free SO2, and withstand wide ranges of temperature and pH. But unlike CL23, SN9 adds weight and high glycerol production, making it preferred for high alcohol sweet wines. Can ferment down to down to 10C (50F). SN9 is ‘fermentation friendly’ in that it produces zero foam, starts fermenting rapidly, and can be used to restart stuck fermentations. SN9 is the most osmotolerant and the fastest-clearing of all Vintner’s Harvest strains.

Best Styles : Aged Reds, Blush, Cider, Fruit Wine, Sparkling Cuvée, Whites, Young Reds

1st time I have used this brand I am very pleased with its performance.

David Sprayberry
Very pleased so far

Wine is still fermenting at this point but all tests look great.

The Hercules of yeasts

This stuff is insane. I I used it for a banana wine and the first night it fermented so vigorously that it blew the airlock off. My fault, I made more must than could fit in my fermenter and thought filling it a bit more wouldn't be a problem. Now, when I saw the open bottle the next morning, I thought for sure I had lost the batch. Decided to sanitize the airlock and see if it could be saved. Four hours later it's bubbling like crazy, and no signs of infection a week later.

If you could have 1 yeast - this is it

I have used SN9 for several years as my "go to" yeast. It has always been a reliable starter, ferments with very little foam, has a good temp range and high alcohol tolerance. It has helped me "unstick" a couple of stuck fermentation's. I've used if for white "tea" wines, like Dandelion and hearty reds like black raspberry and cranberry. Kept in the fridge, I've used packets that were beyond the "best by" date with excellent results. It's hard to find in the local wine stores, and this is by the far the best price for SN9 I have found anywhere.
