Wine Conditioner is a combination sugar/sorbate solution for adding to a fermented wine in order to give it some residual sweetness. The sorbate helps prevent fermentation of the sugar that you are adding. The more Wine Conditioner you add the sweeter the wine gets. We do have a selection of wines that have a sweeter finish that is appropriate to style- that do not require the addition of Wine Conditioner. Just check the sweetness ratings of all of our wines to see what suites your taste best.
