Know about potassium metabisulfite
Potassium metabisulfite, also known as the food additive E224
or potassium pyrosulfate, is a food preservative which preserves the natural colour of food and protect against bacteria.
When should I use potassium metabisulfite?
Potassium metabisulfite is often called a stabilizer because it serves
to prevent spoilage and further fermentation by removing
oxygen. However, this serves another purpose it preserves the flavor and color
of a wine. An over oxidized wine can taste cooked or flabby (lacking body).

The potassium metabisulfite preservative is an additive that is commonly
used in households for wine-making, but also for preserving all
kinds of vegetables and fruit. It is used for sulphurising wine because it
releases sulphur dioxide that has bactericidal properties.

Harmful if swallowed or inhaled. May cause severe and possibly fatal
allergic reactions if inhaled or swallowed by some asthmatics and other
'sulfite-sensitive' individuals. Reacts with acids to form toxic and irritating
sulfur dioxide gas.
How does potassium metabisulfite work?
Potassium metabisulfite in wine
In wine making, potassium metabisulfite acts as an antioxidant,
removing all the oxygen suspended in the wine, which slows down aging.
Natural cork closures enable micro-oxygenation by allowing tiny amounts of
oxygen back into the wine so flavours can reach their potential.

6 months
When stored at a maximum temperature of 25 °C and a maximum relative
humidity of 45%, the shelf life is 6 months.
Can you add too much potassium metabisulfite to wine?
As doses of potassium metabisulfite or Campden tablets are added
throughout the wine making process, the amount of bound sulfite builds up.

fermentation, it ensures your yeast has finished. It acts as a stabiliser
to completely kill yeast at the end of fermentation allowing safe bottling of
your home made wine and beer.
How much potassium metabisulfite is in a Campden tablet?
Campden tablets typically contain 0.44 g each of sodium metabisulfite
(plus filler) and 8 of these are equivalent to one half level teaspoon (2.5
mL) of sodium metabisulfite. Other Campden tablet formulations use potassium
metabisulfite.
How is potassium metabisulfite used in beer?
Dissolve potassium metabisulfite in cold water and add directly. To optimize the
use of PMBS, we recommend trials prior to the routine use of the antioxidant.
This assures optimum protection and uniform beer quality. PMBS is normally
added at 10 – 20 ppm is (0.25 to 0.50 lb/100bbl.; 1-2 g/hl) of beer.
How is potassium metabisulfite used to make wine?
Potassium metabisulfite is one of the most important winemaking
compounds. It is an antioxidant and bactericide that releases sulfur dioxide
into wine must. Use 1/4 teaspoon per five gallons to add 50 ppm.
How much metabisulfite is in a gallon?
If the normal recommended dose of sodium metabisulfite is used—1/16
teaspoon per gallon—the residual sodium being added is equivalent to one
slice of pickle per case of wine. Not enough to affect the flavor and certainly
not enough to affect your diet.
Can I sanitize with potassium metabisulfite?
In stronger doses, potassium metabisulfite works well to sanitize your
equipment, with no negative consequences. Make a solution of 8
teaspoons dry measure of potassium metabisulfite added to 1 gallon (4
liters) of warm water. Rinse your equipment in this solution for about 5
minutes, and let drip dry.
Is metabisulfite safe for skin?
Sodium metabisulfite must be clearly labeled on the food packaging
because some people are sensitive to sulfites. ... After evaluating the
available data, the Cosmetic Ingredient Review Expert Panel concluded that
sodium metabisulfite was safe for its indicated uses in cosmetics and
skincare products.
How much potassium metabisulfite per gallon of wine stops fermentation?
The dosage should be listed on the containers they come in, but you want
to use 1/2 teaspoon of potassium sorbate per gallon and 1/16 teaspoon
per gallon of either: potassium metabisulfite, sodium metabisulfite,
or 1 Campden tablet per gallon of wine.
What is the chemical formula of potassium metabisulfite?
