* Required Fields



Potassium Sorbate AKA the "wine stabilizer", dissolves completely in wine to prevent yeast from fermenting. Use in sweet wines, sparkling wines, and some hard ciders prior to bottling to prevent carbonating your wine. It may be added to table wines which exhibit difficulty in maintaining clarity after fining.

When added to wine, potassium sorbate produces sorbic acid, serving two purposes:
At the point when active fermentation has ceased and the wine is racked for the final time after clearing, potassium sorbate will render any surviving yeast incapable of multiplying. Yeast living at that moment will be permitted to continue fermenting any residual sugar into CO2 and alcohol, but when they die no new yeast will be present to cause future fermentation.
When a wine is sweetened before bottling, potassium sorbate is used to prevent refermentation when used in conjunction with potassium metabisulfite.
Please note: this product will not stop an active fermentation.

Use 1/2 tsp. per gallon.

Needed yeast in a hurry!
I needed yeast and other supplies in a hurry as I was in the middle of making a batch of wine and my local supplier was out of stock(s). I placed my order with Midwest Supplies and received my order without a single hiccup in my 'wine-ing' schedule!

Good for back sweetening
I add potassium sorbate before I back sweeten my meads and wine. This is the only way to add fermentables without them being consumed ending in bottle bombs.

Lets me make sweeter wine
I'm not fond of bone dry wine, I want them a little sweeter. But I don't want exploding bottles either. This is a good additive because I get both. Sweeter wine and no bottle bombs.

should be on your shelf
Depending on what type of wine you make, you should have this available. If you want a sweeter wine, you will need it. You won't be able to get sweet wine without it. I use it when I need to sweeten wine.

Use in my back sweetened cider
After my cider is done fermenting I like to back sweeten with juice concentrate before kegging. K Sorbate along with keeping it cold helps to stop the yeast from picking back up. Stuff works great.

Fro sweet wine, without broken glass
Occassionally I want a sweeter wine and I don't want to add sugar so I use Potassium sorbate. Potassium sorbate does not destroy wine yeast. You need to use a Campden tablet to stop the yeast and prevent bottle bombs.
