Review: Works a treat. - It always works for me. The plastic tub seals right up and it can last a fair while, although not sure how long. It's a bit pricey buying it on here, but when I compare that with travelling a good distance to my nearest home brew shop or getting it delivered, it makes the extra expense on desertcart worth it!

## Questions & Answers

**Q: I need stabilizer for cellar seven wine kit i lost it**
A: This stabiliser can be used in home brew wines such as Cellar 7, you use around half a teaspoon per gallon, Best regards, Home Brew Online

**Q: Does it have an expiry date, what sort of shelf life does it have?**
A: Yes, it has a "best before date of approximately 6 months. I am still using this product, even though I bought it over a year ago. Still doing its job well.

**Q: Will this work for halting fermentation of beer?**
A: It won't actually stop fermentation itself. All Potassium Sorbate does is prevent yeast from multiplying, so it doesn't stop an established fermentation. It stabilises wine by preventing the yeast from multiplying after going dormant.

**Q: Is this same as adding finnings**
A: No, this doesn’t clear your brew. It’s stops the fermentation process. Use it before bottling so you can be certain fermentation won’t continue, which could cause your bottles to blow.
