Description

Details

Potassium Metabisulfite is a widely used winemaking agent. It effectively kills wild yeast and bacteria. The condition of your grapes and pH levels may vary the amount needed. This agent helps to clear the way for your yeast, better allowing it to do its job. Sulfites also aid in inhibiting enzymatic browning in white wines, and improves the flavor when used correctly. Metabisulfite does lose potency over time, so you should replace your supply at least annually. If you have some old metabisulfite, it can be used for sanitizing purposes.

Dosage:
  • 1/4 teaspoon per 5 gallons, which yields 50 ppm.

Great sanitizer
As other reviewers mentioned, this works as a great sanitizer. A gallon can be mixed up and stored up to 6 months. Most books I've read also suggest adding some with each wine racking. The potassium version is preferred over the sodium version as well. The cost difference is not significant at all.

Must have for aging
Used this for aging my wine kit from Midwest. The instructions say to use if you intend to store your wine for extended periods of time (most reds). Purchased the 1 lb bag because it is much cheaper per gram then the smaller bottle.

De-chlorinate your water
You can remove Chloramine with this for home brewing, as well as use it for your wine making. Easier to measure, if you have a very precise scale.

Sanitation is key
Absolutely necessary to protect your wine from the horrors of bacteria and oxidation. A little goes a long way for sure, so it can be hard measuring out the right amount for smaller batches.

Great for long storage of wines
If you're making wine and want to age the wine for long periods (like over a year) then adding a little extra of this is advisable. Wine kits come with some in them, but the instructions say to add a little extra if you plan on storing for a long time.

Great addition
This is a must. Me and my wife love wine, but 30 bottles from one kit is a lot, and we would like to ensure it lasts.

Does Its Job
The potassium metabisulfite was used in my winemaking to help kill wild bacteria/yeast so that the wine wouldn't go over the fermentation level wanted. I am sure to replace my supply once a year as I have noticed that over time it seems to really clump up and have read it becomes less effective.
