Potassium Metabisulfite powder is a wine additive used to kill wild yeast and bacteria, and it acts as a potent antioxidant, protecting both the color and flavors of wine.  "Meta" is a workhorse anti-oxidant and source of sulfur dioxide that comes as close to being mandatory use as any additive in winemaking.

1/4 teaspoon per 5 gallon batch yields about 40 to 45 ppm.

Available in several sizes.  Select your size, or click here for a bulk 55 lb quantity of potassium metabiulfite.


Replace every 12 months and keep dry and out of direct sunlight.

Sodium metabisulfite is an alternative for amateurs, as it acts in the same way as potassium metabilsulfite, but US commerical wineries are legally not permitted to use the sodium metabisulfite.

Warning: Adding meta AFTER a wine has been cold stabilized may render the wine unstable once again.

Potassium Metabisulfite Powder - Food Grade
Greetings! We use quite a bit to sterilize equipment not to mention its primary purpose. Purchased the 10lb. container recently and noticed the label has lost the grams per gallon potency, i.e.: 1 gram per gallon yields 150 ppm. For us old guys we weigh, not just measure and desire knowledge of how many ppm we are adding. I am very sensitive to sulfites so I try to keep them to 25 ppm in all our wine. You gotta love Presque Isle Wine Cellars, they are the only company from which I buy supplies. Been using their services since the '80's

Packaging a plus
Nothing fancy but I like the fact that I can just put the jug on a shelf and not worry about spilling anything. I often order from piwine to avoid having to deal with bags of ingredients .
