ABV Aromazyme is a food-grade enzyme preparation with a strong glycosidase activity that enables biotransformation to occur during fermentation creating a range of potentially bold new primarily fruity flavours. Biotransformation is particularly sought after when brewing NEIPA (hazy) beers.

With a dosage rate of 0.05g/L, this vacuum sealed pouch containing 1.2g of Aromazyme is sufficient to dose 23L - 24L of beer.

For Optimal Results

When using ABV AROMAZYME, the following factors should be considered: Dry-hopping early in fermentation will result in greater extraction of terpene glycosides. Add the enzyme mid-fermentation to allow time for the enzyme to break down glycosides and the actively fermenting yeast to consume the glucose released from the reaction, while minimising volatile loss from CO2 stripping. Avoid adding enzyme after filtration.

Benefits

• Increases the diversity of hop flavours and aroma by changing the ratio
  of specific terpene compounds
• Enhances the beer mouthfeel and drinkability by reducing unpleasant harsh bitterness
• Slightly increases wort fermentability
• Expresses more character from less sophisticated hop varieties

Dosage Rate & Application

• The recommended dosage is 5g/hL (0.05g/L).
• ABV AROMAZYME has optimal activity between pH 3.5-6.5, although lower activity is still observed at pH 3.0 for use in sour beers. The optimal temperature range is 15-65ºC.
• Dilute the enzyme in an adequate amount of water (~ 1g in 10ml) to ensure even distribution within the fermenter.

Calcium carbonate (CaCO₃) is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and egg shells. 

In brewing calcium carbonate may be used during the mash to increase the mash pH (reduce acidity), however it may not increase mash pH as much as desired. Click here to read a detailed analysis of calcium carbonate in brewing written by A.J. deLange.

In wine making calcium carbonate may be used to reduce acidity levels in must. It should only be used before fermentation and will reduce tartaric acid levels before malic or citric acids. It does not require cold stabilisation to precipitate out like potassium carbonate, but it will take longer and may affect flavour.

Calcium chloride is a crystalline salt with the chemical formula CaCl₂. It is solid at room temperature and highly soluble in water. It is one of the primary components in the measurement of permanent water hardness.

In brewing calcium chloride may be added to brewing water to increase calcium levels. Proper calcium levels in brewing water can:

• reduce mash pH
• preserve mash enzymes
• increase extract yield
• improve yeast growth and flocculation
• accelerate oxalate removal
• reduce colour.

Chloride is believed to promote a palate fullness, sweetness, or mellowness within the flavour profile of beer.

Before adding salts to your brewing water you should obtain a water analysis report to enable you to calculate the amount of salts in your brewing water after making any additions. Refer to the Brewing Resources page for some links to water chemistry calculators.

Calcium Sulphate (In brewing calcium sulphate (gypsum) may be added to brewing water to increase calcium levels. Proper calcium levels in brewing water can:

• reduce mash pH
• preserve mash enzymes
• increase extract yield
• improve yeast growth and flocculation
• accelerate oxalate removal
• reduce colour.

Lactic Acid is primarily used in brewing to reduce the pH of brewing water to ensure the optimum pH for enzyme activity during the mash.

It may also be used to reduce the pH of sparge water to reduce the risk of tannin extraction. 

In Germany, some breweries will maintain lactic fermentations and use the resulting liquid to make pH adjustments during the brewing process without breaking Reinheitsgebot.

A milk sugar that is not fully fermentable by beer yeast. Adds body and sweetness to beers such as sweet stouts and milkshake IPA’s.

Add at the end of the boil.

Magnesium Sulphate (MgSO₄), commonly known as Epsom Salts, is typically the secondary ion in hardness in water.

Magnesium, like calcium, will help to reduce mash pH, however it is not as effective in lowering pH as calcium.

It accentuates flavour with a sour bitterness, when present in low concentrations and can be used very effectively in pale ales and IPA's.

Magnesium is also an important yeast nutrient aiding in flocculation, however sufficient magnesium should be supplied by the malt during the mash. As such it should only be added to brewing water for its flavour effects.

Mangrove Jack's Beer Finings are a gelatine based fining that will help to clarify your beer, removing unwanted compounds and firming up natural sediment for a crystal clear beer.

Instructions: Dissolve sachet contents into half a cup of luke warm water (not hot). Stir until completely dissolved. Add this solution to your beer after fermentation. Allow settling for two days before racking off, bottling, or kegging.

GMO free.

Used for making drier, lower carb beer styles. Add with the yeast to break down more of the malt sugars which allows the yeast to ferment them for a lower carb, drier beer. This enzyme may extend fermentation time so ensure the specific gravity is stable for 3 days prior to bottling.

Used to improve clarity for crystal clear beer and wine. Will also remove unwanted compounds resulting in smoother flavour. Sufficient for 250ml of bear or wine.

For 25 litres extract 250ml of beer or wine from the fermenter. Add 100ml of isinglass finings and mix well before adding back to the fermenter. Stir well and leave for 24 - 48 hours before packaging.

Keep refrigerated once open.

Mangrove Jack's Liquid Beer Finings help to clarify your beer; removing unwanted compounds and firming up natural sediment for a crystal clear beer.

Protafloc granules is a granular carrageenan product which is added to wort in the kettle to enhance protein removal as the wort cools. 

Benefits

• Natural product which removes substantial quantities of haze forming material without affecting head retention
• Produces brighter worts, reducing the amount of finings required later
• Increases rate of fermentation and attenuation
• Increases filter runs
• Prolongs shelf life in small pack beers

Application

Protafloc Granules should be added to the kettle ten to fifteen minutes prior to the end of the boil or to the whirlpool if this is not possible. This allows the powder to dissolve and disperse the carrageenan into the wort. Should Protafloc be added early in the boil, degradation of the polymer may occur and product efficiency is lost. The reaction between wort proteins and carrageenan is pH dependant and occurs at an optimum pH of 5.3. Below pH 4.4, the reaction does not occur and little benefit is gained from using Kettle finings.

Dosage

The usual dosage rate is 0.0075g - 0.048g per litre of wort. This equates to 0.18g - 1.15g for 24 litres of wort.

Servomyces D50 is a naturally zinc enriched single-strain brewing yeast (from the prestigious Hefebank Weihenstephan) that is used as a biological yeast nutrient. The propagation and drying process of Servomyces D50 has been specifically designed to accumulate a high concentration of zinc that is essential for healthy alcoholic fermentation. 

Usage

1 g Servomyces D50 is used for 100 litres of wort for fermentation. This equates to 0.1g per 10 litres.

2 g Servomyces D50 is used for 100 litres of wort for propagation. This equates to 0.2g per 10 litres.

Practical trials have shown that addition of Servomyces D50 should be made to the kettle about ten minutes before the end of the boil.

Ultra-Ferm is a liquid amyloglucosidase (highly concentrated) from selected classical strain of Aspergillus niger that completely hydrolyzes dextrins into fermentable glucose. It helps eliminate residual sugar, allowing you to achieve a dry flavour profile. Ultra-Ferm is often used to make low calorie or Brut IPA beers.

APPLICATIONS:
1) To reduce saccharification times.
2) To saccharify unmalted cereal brews.
3) To increase attenuation.

FUNCTION IN BEER PRODUCTION:
Brewers often want to produce light beers or dietetic beers. In these cases the brewer wants a controlled or complete hydrolysis of starch and dextrins to fermentable glucose. Traditional brewing methods permit only 75 to 80% hydrolysis of starch present in the grain raw material. Ultra-Ferm amyloglucosidase permits total hydrolysis of dextrins to fermentable glucose, from all types of starch.

In the brewhouse, the recommended application dosage of Ultra-Ferm is 0.8 to 3.2L per ton of starch. It can be added at the beginning of the mash-in. Ultra-Ferm optimal pH is between 3.5 and 5.5. Temperature should not exceed 60°C. Amyloglucosidase activity is completely destroyed when the wort is held at 85°C for 10 minutes.

FUNCTION IN SPIRITS PRODUCTION:
After starch liquefaction by alpha-amylase, dextrins are hydrolysed in glucose by amyloglucosidase, before alcoholic fermentation. Ethanol production is faster and yield is higher. The recommended saccharification temperature is 60°C.

A suitable substrate for saccharification is a liquefied starch with a dextrose equivalent (DE) between 10 and 20. A higher DE than 20 might reduce the saccharification efficiency. The concentration of the substrate will also influence the saccharification efficiency. A concentration of 20-25% is a general practice. ULTRA-FERM dosage, for given reaction time, depends on the amount of glucose requested. It is usually recommended to add 400 ml per ton of starch for a fast hydrolysis. Possible pH range of use is from 3.5 to 5.5 with optimal between 4.0 and 5.3.

Optimal temperature is 60°C. Amyloglucosidase activity is completely destroyed when the saccharified liquor is held at 85°C for 10 minutes. As an example: a yield of 94% glucose can be obtained after 40 hours with 36000 AGI per kg dry matter; after 72 hours with 17000 AGI/kg and after 85 hours with 13000 AGI/kg, at pH 4.5 with temperature 60°C.
