Addition of Copper Finings Murphy and Son Ltd

General Considerations

• Copper finings are derived from seaweeds and the active ingredients are carrageenans and furcellarans. They are available as dried seaweed, e.g. Irish Moss, or as extracts in the form of either pellets or powders.
• Copper finings can be added directly to the copper. Alternatively powders can be slurried with cold liquor prior to addition.
• The optimum rate of addition of finings should be determined annually when starting the new season’s malt or whenever there is a change in the type or supplier of malt.
• The rate of addition of finings will affect the clarity of both hot and cooled wort. Incorrect addition of copper finings (both over and under) can give poor fining action in the cooled wort and beer which fines with difficulty.

Range of Values

• Optimum rates of addition may vary from one malt variety to another, from season to season and from brewhouse to brewhouse. Murphys are happy to offer an annual optimisation service to our customers, either in our labs or on-site.
• Typical rates of addition are in the order of 1·0 – 5·0 gms per Hectolitre (10 ppm to 50 ppm, 1·63 – 8·15 gms per barrel).• Hot breaks should consist of large flocs in bright wort. Cold breaks should be a heavy fine sediment in bright wort.
• The haziness of worts from the heat exchanger should be within the range of 2 – 6 E.B.C. haze units. If worts are too bright fermentation problems are sometimes encountered because the release of carbon dioxide and consequent ‘stirring action’ that such a release promotes, are hindered.

Operational Protocols

• When casting to a hop-back, finings are added during the last 5 to 15 minutes of boiling. If the practice is to recycle worts at the hop-back finings can be added at this point. When using a Whirlpool, finings should be added at casting from the copper.
• Whatever method of addition is used the copper finings must be evenly dispersed.
• Rates of addition should be optimised according to results obtained.

Measurement Protocols

• The formation of hot breaks is assessed visually after sampling from the copper at casting.
• Cold breaks are assessed visually after sampling from the cold wort mains and allowing to stand for a minimum of 2 hours.
• Rate of addition of finings; a graph is drawn of casting, gravity against rate of addition of copper finings and breaks are indicated as excellent, good or poor. The rate of addition is altered when poor results are observed.

Tate and Lyle products from Murphy and Son

We have recently reached an agreement with ASR, more commonly known as Tate and Lyle, to become their distributor to the brewing industry. This arrangement opens up their full portfolio of products to ourselves and gives significant benefits to ourselves as well as strengthening a product line in which we have historically been able to offer relatively few materials. We will look to hold limited quantities of golden caster sugar, replacing the material we use at present. All other lines will be bought to order as customers require them.

Tate & Lyle® is the largest cane sugar brand in the United Kingdom and has been produced at the same refinery on the banks of the River Thames in London since 1878. Tate & Lyle Sugars are part of ASR Group – the largest vertically integrated cane sugar producer in the world. They focus principally on bringing specialty sugars and functional ingredients made from sugar cane to the EU marketplace.

BREWERS CLAREX – ENZYME THAT PREVENTS CHILL HAZE

brewers clarity

Brewers clarex used to prevent chill haze

Brewers Clarex is an enzyme that prevents chill haze in beer. This product is so effective that it reduces or even eliminates the costly stabilisation procedure from the brewing process.
This enzymatic solution increases production capacity and reduces operational and energy costs as well as reducing your CO2 footprint.
Chill haze in beer results from precipitation of complexed polyphenol and proteins during cold storage. This precipitation has been shown to result from hydrogen bonding between polyphenols and the proline rich fraction of particular polypeptides. This haze develops over time and, initially, is reversible (haze disappears when temperature of beer increases). The chill haze can become permanent as the hydrogen bonding gets stronger.
Brewers clarex prevents precipitation by hydrolysing the sensitive (haze active) polypeptides. It cleaves specifically the sites where such hydrogen bonding occurs. The specificity of the enzyme ensures that no other beer parameters are affected.
Brewer’s clarex can be used with all kinds of malts and other raw materials. The product is added to cooled wort at the beginning of fermentation.
The required dose rate is determined by:
-the percentage of barley malt, raw barley and /or wheat of the total grist composition
-the specific gravity (plato) of the wort at the beginning of fermentation.

ZETOLITE – Flavour modification Reduces H2S and DMS off flavours

ZETOLITE – Flavour modification Reduces H2S and DMS off flavours

charles drinking

Beer Flavour modification.

It is well known in the brewing world that zinc and copper are required by yeast in trace amounts for cell growth, respiration and reproduction. They enjoy better viability and vitality when these compounds are present in the nutritional mix presented to the yeast.

Murphy & Son Ltd in conjunction with the Zetol Cooperation have developed a product called Zetolite that can be added to wort at the start of fermentation or to beer at the start of maturation to assist in the healthy growth of yeast and in particular to either prevent or reduce the incidence of sulphidic compounds such as hydrogen sulphide or dimethyl sulphide.

Zetolite consists of an aluminosilicate carrier, commonly called zeolite, which is impregnated with either zinc or copper ions. It is a pale pink/red or dark grey powder and is dosed at low levels. There are two types of Zetolite, 63 and 65 being copper and zinc respectively.

Zetolite 65, the zinc-based product, is dosed to wort prior to fermentation at a rate of 0.25 – 1.0g/hl. It prevents the formation of these sulphidic and sulphitic off-flavours/aromas.

Zetolite 63 is the copper-based product and is dosed to beer at the end of fermentation or at the start of cold maturation. Dosage rates are typically 2.0 – 3.0g/hl. It may be so that sulphur-based off-aromas have been detected in the cold beer but with low temperatures, the brewer cannot wait the time necessary to naturally remove the unwanted volatiles. By dosing Zetolite 63 into the cold beer, the residual yeast is stimulated in the presence of the copper to metabolise the sulphur off-flavours quickly away.

Murphy and Son sell this product in 250g, 10kg or 20kg packs.

Ascorbic Acid – effective anti-oxidant, increases shelf life and prevents paper off flavours

ASCORBIC ACID E300 – STABILISER is supplied as a fine white to off –white powder.

Perfect pint

Ascorbic Acid can help make a perfect pint

BENEFITS

  • Is an economically effective anti-oxidant
  • Reduces the susceptibility of beer to oxidation haze
  • Increases the shelf-life of pasteurised and non pasteurised beers
  • Prevents “papery” (oxidation) off flavours in the final product

Application:
Solutions of ASCORBIC ACID should always be freshly prepared and treated into the bulk of the beer without delay, if possible metering into the flow of beer to tank. Anti-oxidant treatment is more efficient when added before the beer has had contact with air, i.e. as soon as practica-ble after fermentation. Addition of the material prior to cold storage is common practice, in which case the anti-oxidant should be added when the tank is almost full to minimise contact with air.

Beerstone Remover – Nipac B – A Nitric and Phophoric Acid Blend

NIPAC B  – Beerstone Remover

Corner-Technical

Beerstone removal

As a brewer you may have a problem with beerstone build-up in brewing vessels and containers.
Beerstone is a compound called calcium oxalate, and if not completely removed can harbour microorganisms. Beerstone is a common factor in wild yeast infections within breweries, it can also act as a nucleation point and cause gushing.
The removal of this material is carried out by using a concentrated formulation of nitric and phosphoric acids.

Nipac B is designed primarily for this application in breweries and is formulated to be low foaming and is suitable for use in recirculation applications. It can be used as an alternative to caustic based detergents in breweries for the cleaning of bright beer tanks and tankers whilst under CO2 atmosphere. A gel version exists for manual application where recirculation of the product is not possible.
