The best way I know of to stop an ale fermentation is to crash cool the beer; that is, chill it to 32 °F (0 °C) as quickly as possible. If lager yeast is not already dead, this method will work on it as well.
A dry hopped beer is one in which the hops are added at the beginning of the brewing process. A wild fermented beer, on the other hand, is a beer that has been inoculated with wild yeasts and is then allowed to ferment for a period of time before being bottled or kegged.

How long does it take homemade wine to stop fermenting?
The initial ferment will take seven to ten days to complete. Wine requires a two-step process. A secondary fermentation is required after the primary one is complete. This is when the wine is aged in oak barrels for a minimum of two years. The first step in the aging process is the addition of yeast. Yeast is a microorganism that is able to break down sugars into alcohol and carbon dioxide.
When yeast is added to a wine, it will begin to ferment the sugars and convert them to alcohol. Once the yeast has finished fermenting, the remaining sugars will be converted to CO2, which is then released into the air. The wine will continue to age for approximately two weeks, after which time it is ready for bottling.
Does Campden tablets stop fermentation?
Contrary to what most people believe, Campden tablets will not stop a fermentation completely so they should not be used to stabilise a wine. The yeast is likely to stall if you add Campden tablets while it is still active.
Why won’t my wine stop fermenting?
Bringing the temp up is enough to get the stuck fermentation going again if the temperature is too low. The yeast can be roused by stirring it with a sanitized spoon. It is possible to put the yeast back in suspension. If it doesn’t, you’ll need to add more yeast.
If you’re not sure how much yeast you need, start with 1/2 teaspoon of yeast per gallon of wort. You can also add a few drops of liquid yeast nutrient to the starter to help it get going, but it’s not necessary.
Can you stop wine fermentation early?
As you point out, sometimes it’s desirable to halt a fermentation before it’s complete, to make a wine in an “off-dry,” or slightly sweet style. One way to slow or stop the wine’s growth is to lower the temperature, but it can also cause the wine to go bad. Another way to slow down fermentation is by adding yeast. Yeast is a microorganism that lives on the surface of wine grapes.
When the yeast eats the sugar in the grapes, it produces carbon dioxide and carbon monoxide, both of which are toxic to humans. If you add yeast to your wine, however, you don’t have to worry about it spoiling. You just need to wait for it to finish fermenting, and then you can add more yeast if you want to speed up the process.
