If you are making wine from fresh fruit, I always recommend adding sulfite to homemade wine about 24 hours before adding the yeast. Leave the wine must uncovered during this 24 hours so that the sulfite gas may dissipate. Then add the wine yeast as you normally would.

Why do you add sodium metabisulfite to wine?

Sodium Metabisulfite is a common additive used to preserve and stabilize wines, ciders, and occasionally beers. When added to wine or must, it forms sulfur dioxide gas (SO2). This prevents most wild microorganisms from growing and acts as a potent antioxidant, protecting both the color and delicate flavors of wine.

How much metabisulfite do I add to wine?

It is an antioxidant and bactericide that releases sulfur dioxide into wine must. Use 1/4 teaspoon per five gallons to add 50 ppm.

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. If it builds up too much you can actually taste it in the wine. It also stymies any bacteria or mold that may be wanting to grow in the wine.

What is 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.

How long does sodium metabisulphite last?

This produces a re-useable solution that will last for about 2 months. Keep it tightly sealed in a glass or plastic container only (it will corrode metals). To sanitize simply rinse your equipment and let it drip dry for 10 minutes.

Do you need to rinse sodium metabisulphite?

Sodium Metabisulphite creates an inert gas called Sulphur Dioxide (SO2) when mixed with water into solution. Drain solution out of equipment but do not rinse or dry before using. Use immediately once sterilised.

Is sodium metabisulfite and potassium metabisulfite the same?

What is the difference between potassium metabisulfite and sodium metabisulfite?

How bad is sodium metabisulfite?

* Sodium Metabisulfite may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Sodium Metabisulfite can irritate the lungs. Repeated exposure may cause bronchitis to develop with cough, phlegm, and/or shortness of breath.

How much metabisulfite is in a gallon of wine?

But in reality, this is somewhat futile. 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 potassium metabisulfite back sweeten a wine?

By adding potassium metabisulfite after you’ve stopped fermentation completely you can then back sweeten a wine with little risk of rekindling the fermentation of newly added sugar.

How much potassium metabisulfite do I add in grams?

The following equation can be used to determine how much potassium metabisulfite you need to add in grams. This formula is based on US gallons of wine and comes from The Wine Maker’s Answer Book by Alison Crowe. If you don’t have a scale to measure your potassium metabisulfite a generally accepted equivalent is 1/4 tsp = 1.4 grams.

What happens when adding sulfites to wine?

When adding sulfites to wine, usually in the form of potassium metabisulfite, some of it will become bound while the rest will remain free. You can’t predict how much will become bound so you’ve got to add potassium metabisulfite, test it, then adjust as necessary.
