In a number of cases you may find it’s desirable to stop the fermentation operation before it comes to a stopping on its own. The most popular reason for wishing to cut off the fermentation process would be that you have concluded the wine already has achieved right measure of sweetness which you want and you don’t care for it to progress any further.
Through halting the fermentation then, many winemakers believe that they will be able to preserve the amount of sweetness which the wine has currently achieved and if you need a very sweet wine, like a dessert wine, this is quite acceptable. The idea behind stopping the fermentation process is that if you were to permit the wine continue the fermentation process it’d become more sweetness over time. When the wine becomes totally dry, the fermentation process will stops on its own with no interference from you.
So, there are several various methods that home winemakers have employed when trying to halt the fermentation process in order to preserve the sweetness but generally these techniques work very well, though.
One of these techniques is using either Campden Tablets or Sodium Bisulfite but you should need to noted that fermentation won’t completely stop using these techniques. You ought to also be attentive to the fact that the prospect is there for some live yeast to be left in the wine, making way for the chance for the fermentation procedure to begin anew. Actually, it’s not unknown for the action to start all over even when you’ve bottled your wine and put it away, but as you know, that couldn’t be a pleasant situation and would result in some terribly bad-tasting wine.
An additional common choice utilized by some winemakers is Potassium Sorbate which is commonly employed for the purpose of making the wine sweeter. When it is utilized for this purpose it’s frequently after the fermentation process has been finished and you’re prepared to bottle your wine. The Potassium Sorbate is then put in with sugar and in this circumstance, it’s to keep the yeast from fermenting the sugar that has just been introduced. When added prior to the end of the fermentation cycle, however, Potassium Sorbate will not destroy the yeast, instead it just makes it sterile. This means that it not producing but it doesn’t end the fermentation.
If your goal is to protect the measure of sweetness that is already in the wine, the best way of doing so is to in fact do absolutely nothing and allow the process to finish by itself until such time as it is fully completed. Once the yeast has been given a chance to settle through a period of several weeks, you will then have the ability to siphon the wine off and then include some Potassium Sorbate with an amount of sugar.
Remember that it’s very important to let the fermentation process complete prior to add things like Potassium Sorbate or additional sugar. If you are not certain whether the fermentation rpcedure has finished, you can determine it by using a hydrometer. Remember that this is the tool that you employ to check the alcohol level in the wine thus if the process has completed, there will be an indication of no more than one on the hydrometer.
