Tannin/phenol compounds will bind with the proteins and also settle out, greatly smoothing the taste of the beer. Warm temperature and a low gravity beer can lead to very quick fermentations- as short as 2-3 days. Also keep in mind that the heat generated by an active fermentation can warm a typical 5-gallon (19-L) batch of beer by 10 to 15 degrees Fahrenheit (5.5 to 8.3 degrees Celsius). If you keg rather than bottle, attempting to stop fermentation is less dangerous since a keg won't explode like bottles can. Homebrewers and some commercial breweries use champagne or other wine yeast to increase the alcohol of a beer after primary fermentation is done by doing a true secondary fermentation, e.g., adding simple sugars to the finished beer and pitching wine yeast. The longer you leave your beer, the more chance the yeast has to get rid of smells and other leftovers from the fermentation process. Once this happens you can then siphon the wine off of the wine yeast settlings and add Potassium Sorbate and Sodium Bisulfite as directed on their packages. You simply add the Potassium Sorbate along with the sugar that is added for sweetening.The Potassium Sorbate stops the wine yeast from fermenting the newly added sugar. This should hopefully stop fermentation, especially if the mead is already cold (many stress factors on the yeast). There are a couple of important factors that will determine the success of your homebrew beer fermentation.

If fermentation hasn’t started at all, then try aerating or oxygenating it again, and preferably re-pitch with a fresh batch of yeast. Pasteurization is a simple process in which a food or beverage is heated to a certain temperature for a certain amount of time to kill or deactivate organisms that could lead to spoilage, including yeast.

This is known as fortifying the wine. The question basically goes something along these lines, “My beers stop fermenting and it’s still at 1.028, what is going on?”. Using sorbate is the only way to have a chance of stropping fermentation and even that can be unreliable. One option for stopping fermentation is to remove the yeast itself through a filtering process. But unfortunately, there is really no practical way to successfully stop a fermentation dead in its tracks.
