Preservatives & Stabilisation

A 0.9 g/L addition of potassium bicarbonate results in a 1 g/L reduction in titratable acidity. Under typical wine conditions and normal use, potassium bicarbonate neutralizes only tartaric acid. It is best used on high acid and low pH wines. Potassium bicarbonate will cause an increase in pH when used.

When dissolved in a solvent, sodium Metabisulphite is a granulated powder that releases sulphur dioxide. It's added to fresh juices in small amounts 24 hours before yeast is added. This will destroy any wild moulds and bacteria that might have been present on the fruit.

As an equipment sanitizer, sodium metabisulphite is often used in higher doses with water. It can be used to clean fermenting containers, hydrometers, bottles, hoses, and anything else made of glass, metal, plastic, or wood that comes into contact with your beer or wine.

Every gallon of liquor contains about 55 parts-per-million (p.p.m.) sulphur dioxide (SO2). Every gramme would give each gallon of liquid 175 p.p.m.
Sodium Metabisulphite is a powerful sterilising powder that, when dissolved in cold water (where it produces sulphur dioxide gas), prevents mould and bacteria from growing on all surfaces.

Brewing and winemaking supplies, as well as beer and wine bottles, are sterilised with this solution.
This product sterilises (sanitises) rather than cleans. This product should be used with clean equipment. 1 tablespoon per 5 litres of water is the recommended dosage. Allow the solution to come into contact with all surfaces. This dilution rate is only for equipment sterilisation.

Note: While sodium metabisulphite is used as a preservative in some cases, you should strictly adhere to food application laws and obtain details about its use from food safety authorities.

WARNING:

The sulphur fumes from this product can cause sensitivity in some people. In enclosed spaces, do not use this product. When working with diluted solutions, gloves are recommended.

TO PURIFY JUICE, ADD 1/16 teaspoon Sodium Metabisulfite per gallon of juice or 8 pounds of crushed fruit. Before applying to the juice, pre-dissolve in a small amount of water. Allow the juice to breathe for 24 hours in an open container before adding the yeast. Dosage should be doubled for overripe and possibly mouldy fruits.

ALL EQUIPMENT SHOULD BE Washed WITH SOAPY WATER PRIOR TO SANITIZATION. For each gallon of water, dissolve 1 teaspoon of sodium bisulfite. Add 1/2 teaspoon of citric acid as well. Put 2 to 3 inches of solution in the bottom of fermentation vessels to sanitise them. Enable the gases from the solution to permeate the inside walls by sealing the vessel airtight for 20 minutes.
You can also put in the vessel other equipment such as hoses, hydrometer, air-locks, rubber stoppers to be sanitized at the same time.

TO Retain the color and taste of the BEER OR WINE during BOTTLING: Add 1/16 teaspoon per gallon of beer or wine. Second, dissolve in a small amount of wine. To prevent re-fermentation, potassium sorbate is also recommended at this time. After adding the ingredients, bottle them right away.

Potassium metabisulfite is a necessary preservative in wine making. It provides sulphur dioxide which helps prevent microbial spoilage and fight off oxygenation.

Paraffin oil, also known as Blandol 15 white oil is a food-grade mineral oil specifically formulated for wine preservation. It creates a protective barrier on the surface of wine in storage vessels, preventing oxidation and spoilage in open or partially filled containers. Ideal for winemakers seeking reliable, non-toxic protection during aging and storage.

Coppox is a premium and consistent grade copper oxychloride. Due to the fine particle size, Coppox has lower application rates. So now you can apply less copper and achieve great results. It is an effective fungicide and bactericide.

Citrogum is a clear, almost colorless Gum Arabic preparation with a low calcium content. Citrogum is recommended for the treatment of wines ready for bottling. It integrates the colloidal content of wine, improving its balance, organoleptic features and stability, mainly tartaric.

It enhances aroma, reduces bitterness and astringency, and increases softness and body. Citrogum’s low membrane blocking capacity (it’s the most filterable gum in the market!), purity and microbial stability ensure that it can be added with confidence at any stage during preparation for bottling.

The sulfur dioxide in the preparation gives the product a long shelf life and enables direct addition to wine even after microfiltration without any risk of microbial contamination.

Applications:

• For tartrate and colloid stabilization in finished wines ready for bottling.
• When added in “liqueur d’expédition” preparation, to improve “perlage” quality.

Dosage:

• 50 - 150 mL/hL
• 100 mL/100 bottles in the liqueur d’expédition

100 mL/hL contributes about 3 mg/L of SO2 to wine.
It is recommended to perform preliminary trials to determine the right dosage, stabilizing efficacy and possible effects on filterability.

Instructions:

Add CITROGUM to clear wine ready for bottling. Due to its low clogging effect and microbial sterility, CITROGUM can be added before or after microfiltration.

Storage:

Sealed package: store away from light in a cool, dry, well-ventilated area. It is recommended a temperature above 10°C.
Opened package: carefully reseal and store as indicated above

Effervescent, granulated potassium Metabisulphite designed to be added directly to wine. When added to wine, it rapidly dissolves on the surface of the liquid, ensuring that its antioxidant effect is maintained where it is needed. Subsequently, it ensures homogenous and rapid distribution of the released SO₂ without requiring pump-overs.

• Applications: sulfiting wines; homogeneous release of SO2
• Dosage: each bag of Effergran Dose 5 releases 5 grams of SO2

Applications:

During fermentation: in conjunction with Pluxbenton N or Bentolit Super, Protoclar ensures a faster and more thorough fermentation process and a finer and more delicate aroma. During clarification: for thorough and optimal clearing of must or wine, combine Protoclar with Pluxbenton N. Ensures good chemical and physical wine stability due to partial adsorption of copper and iron in either ionic or ferric- phosphate complexes, and with powerful selective adsorptive action on polyphenols that cause maderization. With Protoclar the organoleptic properties of wine are improved and the bouquet is more delicate, while the original aroma of the grape variety is enhanced. Thanks to these features, Protoclar is particularly suited to the preparation of base wines for sparkling wines.

For remedying premature aging and oxidative characters: Protoclar noticeably reduces maderization and allowing the original aromas of the wine to be recovered. Protoclar operates on oxidized polyphenols and intervenes in the potential oxidative activity of any un-oxidized polyphenols. This characteristic enables its use as a preventative on wines which have a tendency to oxidize easily.

Dosage:

• 60-100 g/hL for must during clarification
• 20-40 g/ hL during fermentation
• 20-60 g/ hL for wine
• 40-100 g/ hL for remedying oxidized wine

Instructions:

First dilute Protoclar in cold water in a 1:20 solution, stirring continuously to prevent lumps from forming. Allow the solution to rest for a 2-3 hours before use. Then add to the must or wine during a pump over, preferably using a dosing pump or Venturi tube, being careful to have applied the dose directly at least 50% of the wine to be treated.
