preserves the natural colour of food and protect against bacteria
.
How long does potassium metabisulfite last?
If you purchased the potassium metabisulfite within the past
12 months
, it should be fine. The only exception would be if humidity or moisture got to it.
How do you mix potassium metabisulfite?
To use as a general sanitizing solution,
dilute 2 tsp. of metabisulfite in a standard size spray bottle with water
to provide a 1% solution suitable to spray all equipment used in the winemaking process. Or, add 2 oz per gallon of water.
What can I use instead of potassium metabisulfite?
Well-Known Member. If you like dry wines, time. And maybe some cold temperatures to stop the yeast, if it’s getting a little too dry. You could use a
lower-attenuation yeast
if you want a sweet finish, and cold crash to make sure if you’re worried it’ll re-ferment.
What is potassium sorbate used for?
It’s widely used
as a preservative in foods, drinks, and personal care products
. It is an odorless and tasteless salt synthetically produced from sorbic acid and potassium hydroxide. Potassium sorbate prolongs the shelf life of foods by stopping the growth of mold, yeast, and fungi.
What’s the difference between sodium metabisulfite and potassium metabisulfite?
The only difference between sodium metabisulfite and potassium metabisulfite is that
they will leave a residual trace of either sodium or potassium
. Some brewers prefer potassium metabisulfite as they deem it to have a more neutral flavour, the amounts being used however are very small so I tend not to worry.
When should I add potassium metabisulfite?
Generally this is added
right before back-sweetening and bottling
in conjunction with potassium metabisulfite. Do not add potassium sorbate during or before fermentation, as it will severely inhibit the natural yeast multiplication process. Potassium metabisulfite acts as an antioxidant with anti-microbial properties.
Should I use potassium metabisulfite?
Potassium metabisulfite is a necessary preservative in wine making
. It provides sulfur dioxide which helps prevent microbial spoilage and fight off oxygenation. However, figuring out how much to add can be complicated.
Is potassium metabisulfite the same as Campden tablets?

What’s the difference between potassium and potassium sorbate?
Sorbic acid and potassium sorbate both work as chemical additives in numerous products used daily.
Sorbic acid occurs naturally, while potassium sorbate is synthetically produced from sorbic acid and potassium hydroxide
. Each substance preserves food effectively, but work in slightly different ways.

. Potassium bisulfite is used as a sterilising agent in the production of alcoholic beverages.
Is potassium metabisulfite an allergen?
Most cases of sensitivity to sulphites are non-allergic
. Sulphites work as food preservatives by releasing the gas sulphur dioxide. This gas can cause the airway to become irritated and constricted. In such cases, this is not a response of the person’s immune system and is therefore not an allergic reaction.
What is the pH of potassium metabisulfite?
It is also known as E224. Added to wine and cider at the pH range of
between 3.6 and 4.4
it prohibits the growth of wild yeasts, bacteria and fungi giving effective prevention of biological spoilage.
Will potassium metabisulfite stop fermentation?
