More Yeast Energizer can be added later to a wine for stuck fermentation as needed. Dean Mehrkens Thief River Falls, Minnesota Wine Wizard replies: Whoa. There are also many commercial yeast strains which have different microbiological, chemical, physical and sensory aspects that need to be considered, when winemakers decide which yeast selection to choose, for making different wines. This part of the process is probably the most labor intensive step until it comes to bottling. Siphon liquid off sediments into secondary, top up, and fit airlock. If sealed in a container into which no air can enter, yeast cells digest sugar and produce carbon dioxide gas and alcohol. Not very likely, but it does happen. This can cause more problems than if they had just added the dried yeast directly into the must. We can't see it, but it's in our homes, on the trees and plants; it floats in the air.

It is also capable of actually destroying any remnant numbers of these other organisms once it has taken hold of the fruit. SEALING UP THE FERMENTER AFTER ADDING SULFITES: Most wine making recipes instruct the winemaker to add sulfites such as Sodium Bisulfite or Campden Tablets to the juice 24 hour before adding the yeast. Over a short period of time the gases slowly dissipate into the air, usually within 24 hours, making it safe to add your fresh package of wine yeast.Part II, Taking Advantage Of Technology The second reason we should add yeast to wine, is that the strains that are available to us as winemakers are much more suited for making wine than what you will find floating in the wild. 1 teaspoon of wine yeast to 5gallons of potential wine ( is appx.

With pure strains of packaged wine yeast available, the winemaker can now simply put the juice through a sterilization process, killing all the wild molds and bacteria (wild yeast included) and then simply add a fresh strain of packaged yeast back to it, allowing the winemaker to start with a clean slate and a big advantage.The sterilization process is very simple. The problem is that natural yeast is a "package deal". But one thing that yeast does well is mutate, and there are thousands of strains of cerevisiae. You add a product called Campden Tablets to the juice - one tablet per gallon. When the tablets are crushed up and dissolved into a fruit juice, they release sulfur gases into the wine which does the sterilizing. It’s just that when I think of commercial soda my Magic Eight Ball says “Signs Point to No.” But, quite often yeast will let us down and allow these other cultures to take over the fruit and cause it to become something other than wine. without stirring.

Dear Wine Wizard, I did not rehydrate my yeast before I pitched it. Some tend to gloss over this procedure, not knowing its importance. Yeast requires nitrogen for fermentation. Yeast may be added directly to the juice, but it is much better to rehydrate first for up to 20 minutes in water at 90º to 105º F. Follow rehydration instructions and use a yeast nutrient and enhancer, such as Goferm Rehydration Nutrient for best results. They have just gone dormant and are settling to the bottom. For strong-tasting fruits like elderberries use slightly less fruit (say 1.5kg). Yeast digests sugars to make alcohol, and many strains of yeast are cultivated for generations for their potencies. Typical usage rate for yeast is 1 gm / gallon of juice, but being a little short or a little long is not a problem, as yeast reproduces to reach a number at which fermentation takes place.

John Eastwood Cleveland Wine Wizard replies: Rehydrating yeast before adding (pitching) it to juice or must is an important step in assuring a healthy fermentation. For country wines where more than 90% of the fermentable sugars come from simple sugars then the yeast need the addition of yeast nutrients to be able to reproduce and thrive. This is because eventually, the native yeast found in the air does the conversion. We understand that natural yeast is a "package deal". When you crush the grapes, the sugary juices immediately gets into contact with the yeast on the surface and reacts to one another and starts the natural fermentation process. If the fermentation went as it should, there should be about 100 to 150 times the amount of wine yeast you added, originally.
