I like sweet tasting wine. I always add a pint of your wine conditioner before bottling to my wines. Is that all I need to add before bottling or do I need to still add the potassium sorbate? Fred (Occidental, CA) ----- Hello Fred, Glad to hear that the Wine Conditioner is doing the job for you. It provides a very simple way to sweeten your wine. Just pour it into the wine, to taste. You don't need to worry about your wine re-fermenting in the wine bottles, popping corks or anything like that. To answer question about the Wine Conditioner and adding potassium sorbate, it's a matter of how much of the Wine Conditioner you use. If you're using a whole container of Wine Conditioner to a 5 or 6 gallon batch of wine, then no, you won't need to add any potassium sorbate. But, if you are only using some of the bottle, you need to pay a little attention. Here's the specifics: as long as you use at least 1/3 of the container of Wine Conditioner in a 5 or 6 gallon batch of wine, you will be fine. There will be enough potassium sorbate in the wine to prevent it from fermenting the new sugars. But, if you use less than 1/3 of the bottle to the wine, you will need to add a dose of potassium sorbate along with the Wine Conditioner to prevent a re-fermentation from occurring.
