Metabs 5KG

Metabs 5KG

Metabs prevents biological spoilage and microorganisms from growing and reproducing. Its antioxidant properties increase beer's stability and prolong its shelf life.
Metabs can be used to remove free chlorine in tap water, which can cause chlorophenols to obliterate beer's flavour.
When stored empty, you can also use metals to maintain freshness in casks.

Description

Metabs are food-grade sodium metabisulphite tablets that provide a convenient way of adding measured quantities of sulphur dioxide.

Benefits

• Approved for use in food and beverage products
• Prevents microorganisms from growing and reproducing
• Prevents biological spoilage
• Possesses antioxidant properties
• Increases the stability and prolongs the shelf life of the beer
• Can be used for the removal of free chlorine in tap water, which can cause chlorophenolic off flavours in beer
• Can be used to maintain freshness in casks when stored empty
• An easy to use tablet form, no need to measure or weigh
  

Principle

Sodium metabisulphite is a permitted derivative form of sulphur dioxide and is a well-established, proven preservative used in the brewing, wine, and food industries. It is also known as E223. Added to beer at the pH range of between 3.6 and 4.4, it prohibits the growth of wild yeasts, bacteria and fungi, effectively preventing biological spoilage. In addition, its antioxidant properties increase physical stability and prolong the shelf life of beverages.

Guidelines for use

• Check the product is within its shelf life before use
• Read the Safety Data Sheet before use
• The maximum level permitted for SO2 in cask-conditioned beer is 50 ppm. In all other beers, only 20 ppm SO2 is permitted (Council Regulation 1333/2008/EC)
• Sulphur dioxide and sulphites at concentrations of more than 10 mg/kg or 10 mg/litre expressed as SO2 must be labelled as allergenic (European Directive (2003/89/EC)

For the maximum levels permitted for SO2 in wine, please refer to the following:

• Type of Wine Maximum permitted levels of SO2 for EU Law
• Red 150 mg/l (ppm)
• White / Rose 200 mg/l (ppm)
• Sweet 300 mg/l (ppm)

Application and rates of use

Metabs are added to the cask at racking or to the fermenter when used as a beer preservative. When used to keep surplus casks sterile in quiet periods, Metabs are added to the cask after completing the cleaning cycle. Metabs can be mixed into beer or water without further preparation.

• To use Metabs as an addition to beer as a preservative, suitable rates lie between 10 and 50 ppm of sulphur dioxide (SO2):
  - One Metab per hectolitre gives 11 ppm sulphur dioxide (SO2)

• To use Metabs as a means of preserving microbiological stability in empty beer containers:
  - Two Metabs per hectolitre
  

• To use Metabs for the removal of free chlorine in tap water:
  - One Metab will treat up to 14 hectolitres of water

• Please know the maximum levels permitted for SO2 in different beverage styles.
• Please refer to the Guidelines for Use section.

• Keep it in the original container
• Keep containers tightly sealed when not in use
• Maximum storage temperature is 40°C
• Recommended storage temperature is ambient
• The shelf life at the recommended storage conditions and temperature is indefinite
