Lager, Lager, Lager

When some very enterprising German brewers decided to store their beer in the frozen Bavarian Alps through the summer time in the early nineteenth century, little did they know of the impact there new “Lager” creation would have on the world of beer.  Some of these brewers were so moved by the potential of this wonderous brew that they started to leave their Bavarian breweries to spread the word around Europe and refine this new brewing art.  Many on the continent were so moved by the potential of Lager and the Lagering technique that many brewing enterprises started making related products of their own giving rise to styles like the Red Lagers of Vienna.  Much credit also needs to be given to Bavarian brewer Josef Groll who, in 1842, took the brave step of heading to a little-known brewing town called Pilsen in the Czech Republic to try out his new lager recipe.  Following on from this original Pilsner (Pilsner Urquell), innovations and developments in the likes of glass bottle manufacture and refrigeration coupled with a good helping of migration meant lager quickly became a worldwide success.

Lager is as popular as ever and whether its Pilsner, Helles, Vienna Lager or Schwarzbier you are considering brewing, Murphy and Son is the place for everything you need for a flavoursome quality lager.

Liquor Treatment

Our much treasured, annual free of charge liquor analysis now includes a suggested liquor treatment for lager style beers as standard.  If you have not had you liquor checked for a while and you are a Murphys customer please send 50ml of untreated water to our lab for us to check out for you.

Our suggested lager treatment aims for a brewing liquor with adequate calcium for good brewing enzyme activity, yeast flocculation and oxalate and protein precipitation whilst mimicking the low sulphate and chloride levels of Munich and Pilsen for a crisp, light flavour.  This is best achieved with suitable additions of lactic acid to reduce alkalinity with low levels of calcium sulphate and calcium chloride to increase calcium ions.

Malt

Our new closer ties with Simpsons Malt means that we now have in stock ready for dispatch Finest Lager Malt (crushed).  This highest quality malt is slightly higher in Total Nitrogen and slightly under-modified so head / foam and mouthfeel will survive the lagering process. To add to this quality base malt, we can also supply a range of crystal malts, caramalt, wheat malt and Vienna malt (all crushed) direct from our warehouse.

Hops

Whether you are looking for traditional varieties of Noble Czech Saaz and German Hallertau hops, or looking to add a dry hop twist to your brew with new world hop pellets, we are very proud of our close relationship with Charles Faram which means we can supply the best hops around to suit your requirements.

Yeast

On the dried yeast front we are pleased to hold stock of Lallemand Diamond Lager Yeast and three different Fermentis Lager Yeasts.  We also supply wet yeast cultures from the National Collection of Yeast Cultures (NCYC) which houses a vast range of lager strains originating from all over the world which can add the precise character you are looking for.

Flavour control

Diacetyl and Sulphur flavours can be problematic in lagers to help keep things under control we have the perfect products to help.

When added to wort at the start of fermentation, the enzyme Alpha Acetolactate Decarboxylate (ALDC) acts on the diacetyl precursor alpha acetolactate converting it to acetoin.  If alpha acetolactate is not present diacetyl can’t be formed so no buttery off flavours in your beer and conditioning time can be reduced.

To help keep sulphur off flavours out of your beer, Murphys have developed two zetolite products for the job.  Zetolite 65, when added to wort at the start of fermentation will prevent the formation of sulphur off flavours whilst if you notice the undesirable sulphurous aromas in your fermented product, the addition of Zetolite 63 will stimulate your yeast to reduce H2S and DMS aromas during maturation.

Don’t forget…

…an exuberant bright appearance is important with lagers and at Murphys we carry a huge range of finings and stabilisers to help achieve the desirable crisp look from brewers clarex to Super F, Silica and PVPP products, the Murphys Technical team is on hand to get this just right for you.  PGA is also a handy product to help achieve a perfect looking head on dispense.

What should you expect from this year’s malt specifications?

We’ve been discussing the expected malt specifications for the coming year with our malt suppliers and wanted to feed back so you can prepare and tweak your recipes as required.

The malt nitrogens coming into breweries with the new seasons malt are likely to be higher than usual, at around 1.7%. The winters are not expected to be quite as high, but are still above average, predicted at up to 1.5%. This is a result of environmental factors, as last year saw low rainfall which made it harder for the barley to establish properly. Blame the British weather, it’s a national habit and we brewers are no different. You can however, prepare for this and if you need any technical support in doing so, we’re always on hand. The key implications revolve around your use of copper and auxiliary finings, the rates of which will need to be reoptimised once malt is in breweries and will likely increase. You can expect to see the first malts of this harvest in breweries across the country from mid-February onwards.

Could do with a bit more information on the matter? No problem!

It starts with the farmers, who sow different varieties of malting barley in autumn and early winter, known as “winters” and again in spring, known as “springs”, both of which are harvested from early July onwards. The latter are becoming more popular as they tend to be easier to grow but do require more fertiliser to get a decent yield by harvest time. Winters don’t require as much fertiliser making them cheaper for the farmer but extract value to the brewer tends to be less.

In brewing, we refer to the percentage of protein present in the malt as percentage nitrogen, it is quoted on malt analyses and used as a price guide and quality indicator. For example, feed barleys have a high protein content to feed the animals. Brewers however, want nitrogens to be lower, at around 1.4-1.5%. This provides enough yeast growth, flavour and beer foam without any substantial problems with haze, stability and excess yeast growth, above these levels and the later can become an issue. There is therefore, always a focus on this parameter at harvest and purchase time.

How come the percentage nitrogen is predicted as being higher in British malt this year?

The issue is in fact that of last year, where we saw a prolonged dry winter and spring in the main growing regions of the UK, resulting in crops not establishing well. To help crops along, farmers spread higher amounts of fertiliser which in turn pushed the nitrogens up. This is because the fertiliser is taken up by the growing plant and deposited in the developing ears of corn which are the grains harvested as barley for the malt crop. Had they not done this, the crop may well have failed altogether, something which did happen in a small number of districts resulting in some shortage too. The maltsters work with what they get off the fields, blending barleys to get an overall consistency which they can sell to brewers. However from a brewer’s perspective, with already high nitrogens and a limited supply, the quality of malt coming onto the market is weaker when compared to the previous years’ crop. Therefore, the forecast is less stable beer.

As brewers there are various techniques at our disposal to control protein (nitrogen) in the brewing process, and this is where we at Murphys specialise! Carrageenan and auxiliary finings are both process aids that remove this protein. It follows therefore, that brewers will require more of these products to treat the higher nitrogen malt expected this year. Something which we can support with our optimisation services and technical expertise, provided to you by a team of master brewers. Choosing Murphys will be an invaluable decision in 2018.

Kegging, canning or bottling? Have you considered the benefits of Murphy’s Super F?

Since its launch,  Super F has proven invaluable to many of the top craft breweries worldwide, providing great results for beer produced for keg, can and bottle whether filtered or unfiltered.

What is it?

Super F is a rapid action fining, made using our own special formulation of silicate and polysaccharide for rapid sedimentation.  This unique blend makes Super F effective at fining out yeast as well as being an effective finings agent against potential haze forming colloids like proteins.

How’s it used?

Super F is best added when beer is moved from fermenting vessel to conditioning tank with care taken to ensure good mixing.  It is not a suitable addition for cask conditioned beer and should never be dosed directly to cask.  Action of this fining is quite rapid with excellent results achievable within 48 hours.  Super F packs a real punch so dose rates are low with typical doses 75ml-175ml per hl will achieve great clarity (often less than 1 EBC) and a compact sediment.

Benefits

The rapid action of Super F will significantly reduce residency time in conditioning / maturation vessel.  When using this product, the load on centrifuges and filters will be significantly reduced due to brighter beer being presented for further processing.  This gives considerable time and money savings per run.

When kegging unfiltered beer, yeast counts and protein content in the product will be lower and more consistent, leading to a more stable product.

Super F is also vegan friendly and is easy to store (just don’t freeze it!) with a shelf-life of 6 months from manufacture date. Furthermore, Super F is also in accordance with German Purity Law (set into force by the German provisional beer law in its current version 9 [6]).

Finings trials

Introducing a new finings regime to any brewery is a big step.  At Murphy and Son, we pride ourselves on our technical support so before any brewer uses this product we ask that they send a representative two litre sample of their beer to our laboratory where our Research and Development Scientist Dr Ruth Newby and the rest of the lab team will set up optimisation trials.  This will give valuable information on haze and sediment levels for different dosages to provide a starting point for trials and additions in the brewery.  As always, our technical sales team will also be on hand to aid and advise on the products use.

Happy New Beer!

We all go into the new year with ambitions and resolutions, invent a hangover-free ale being a fine example (we’ll leave you with that one). There really isn’t a better time to share some of our aspirations for the new year and celebrate the triumphs of 2017, so ‘happy new beer’ from us all here at Murphy & Son Ltd!

To kick things off we’ve an incredible company milestone from 2017; the launch of Murphy & Son Inc, which saw us solidify our position in the US market. This is only the start of our expansion into the US and global markets more broadly, something we look forward to reporting back on as our endeavours across the pond develop. For now, we are pleased to announce Murphy & Son Inc. is operational. ‘To infinity and beyond!’

Now for a little closer to home. Our site has seen considerable expansion and investment this year, through the installation of our new reception, chilled warehouse and can wash facility. The new can and IBC washers will allow us to clean 800 cans and 50 IBCs in a day! Something which we’re confident will help improve our returnable drum service and supports our food grade commitments.

Our new warehouse with state-of-the-art racking will allows us to double out storage capacity and provide more temperature controlled storage to improve product quality even further!

We’re proud to promote some changes already being set into motion in our Laboratory too. Lab analysis turnaround times have become an even more central focus for the team, as we know you brewers always want your results yesterday! Plus, in the new year we’re taking this one step further and launching a new range of due diligence packages, which will provide structured ongoing quality assurance.

We’d also like to congratulate two of our laboratory team on achieving their General Certificate in Brewing. Well done Adam Divall and Ruth Newby for expanding the expertise of the Murphy team even further!

With a real sense of growth and innovation gaining momentum in our company in 2017, we go into 2018 enthused and ready to continue providing and expanding upon our first-rate customer service. You, our customers, are the driving force behind all the changes we’re making structurally, so we can ensure better service and quality from our one-stop-shop.

‘Look to the future now, it’s only just begun!’

Finally, we’d also like to congratulate you all on another record breaking year and Christmas period. We’ve experienced first-hand your dedication, the incredible batch sizes and the growth of breweries from new kids on the block to established brands. It’s an incredible time to be part of the industry and we’re proud to be at the centre of it working to support each and every one of you, as we have been for 130 years.

In 2018 we’re committed to continuing to improve our service and range so that you can ensure excellence in your brew. Any feedback for us or new year’s resolutions you’d recommend, let us know via info@murphyandson.co.uk or call us for a chat on 0115 978 5494.

We leave you with a quote from British wordsmith himself William Shakespeare…

‘For a quart of Ale is a dish for a King.’

Cheers!

The new impact resistant MurphyHallam Layer Board

We at Murphy & Son Ltd are proud to announce a new design of layer broad, produced in collaboration with Hallam Plastics; the M&H Layer Board. Our design is more durable, weather resistant, safe and strong.

Layer boards are a staple in every brewery and used throughout the supply line. They’re not, however, without their bugbears; prone to cracking in frosty conditions, warping under heavy use and collecting rain water (a cold shower every brewer has begrudgingly suffered once). So at Murphy & Son we thought it about time someone reinvented the wheel.

As with every Murphy product, our Layer Board is designed with the brewer and brewery in mind. It’s compatible with numerous automated systems and manufactured from High Density Polyethylene (HDPE), a superior non-brittle plastic that won’t crack or split in sub-zero temperatures and is impact resistant. Manufactured using engineered structural foam (ESF), the board boasts a high strength to weight ratio, compared to conventional injection moulding techniques. Plus, we’ve even added a simple drainage system so rain water can no longer collect. HDPE is stronger, more durable, more rigid and more resistant to the sunlight’s UV rays than conventional polypropylene, ensuring safer loading and unloading for draymen and fewer breakages.

The board’s superior manufacture is coupled with business acumen. It’s 100% recyclable and returnable for supply chain cost effectiveness. Plus, our boards can be customised; available in a range of colours and with the option to add a logo. A radio-frequency identification tag facility is also available upon request, to enable accurate tracking, deter theft and enhance security. We’ve left no stone unturned.

The latest from Lallemand!

Can I purchase LalBrew New England East Coast Ale Yeast or WildBrew Sour Pitch from Murphy & Son? The answer is yes! Interested? Please email frances.maud@murphyandson.co.uk or call 0115 978 5494 for prices, advice and availability.

So, what can you expect from these two Lallemand latest? The newest kid on the block is LalBrew New England, officially unveiled yesterday (Nov 13th ’17) and it’s an innovation that’s already causing a stir!

The LalBrew New England is a ready-to-use dried strain of Saccharomyces cerevisiae which has been selected for its specific ability to allow hop flavours to remain prominent while also providing the fruity notes championed by the ‘East Coast’ style. The ‘East Coast’ style is a sister style to its West Coast counterpart, but with yeast that naturally produces fruity aromas. An ale with a mixed bouquet of fruit and hops on the nose and when tasted, which is sometimes brewed cloudy and sometimes not.

As we’ve already said, Lalbrew New England is causing quite a stir, the Murphy sales team have already received enquiries and that’s before its official release! In fact, this new yeast has been produced in reaction to a number of customer requests, hence our confidence in its relevance and popularity. It’s also been seen very favourably in the trials executed by several breweries. Like to trial this yourself? Please don’t hesitate to get in touch.

LalBrew New England isn’t the only innovation we’ve seen from Lallemand recently. The first product in the new WildBrew line, Sour Pitch, has also been making heads turn. A zesty addition to your brew style.

WildBrew Sour Pitch, is a ready-to-use dried bacteria. A strain of Lactobacillus plantarum specifically selected for its ability to produce a wide range of sour beer styles. Some of the styles you can brew with Sour Pitch include, Berliner Weisse, Gose, Lambic, American Wild and Sour IPA. In addition to which, if you choose Sour Pitch when brewing your sour beer style of choice, you can ensure unmatched consistency, effortless application, fully assured performance and unparalleled purity!

What’s the brewing industry reaction? Several breweries around the world have executed highly successful pilot brewing trials with Sour Pitch, the results of which have been overwhelming positive. Pair this with the huge buzz we’ve seen in the industry around Sour Pitch since its release at Drinktec 2017 and it’s undeniable that everyone is looking to try it, or rather “unlock their sour potential”.

Finally, WildBrew Sour Pitch has been designed to assist creativity in brewing, but here are a few tips for its application. The ideal temperature for inoculation of WildBrew Sour Pitch is: 35-38C (95-100.5F) optimal but 30-40C (86-104F) will result in effective souring and the recommended inoculation rate is 10g/hL.

IONIC COMPOSITION – Brewing Liquor

Originally, brewing started up in areas where the water supply was suitable for the production of beer, but with the wide geographical spread of modern breweries and modern supply systems, the water available to the brewer can be at best variable and at worst quite unsuitable. The natural water in areas such as Burton-upon-Trent proved excellent for production of bitter ale beers and many brewers will now treat their incoming supply to adjust pH and salts content to emulate Burton water. Where dissolved salt levels are low, it is usually sufficient to make up the concentrations to the desired levels. The most important ions are calcium (Ca++), sulphate (SO4–), bicarbonate (HCO3-), and to a lesser extent magnesium (Mg++), and chloride (Cl-).

CALCIUM (Ca++)
Calcium is a very important constituent and performs a number of functions:-

  • Decreases the pH during mashing and wort boiling, favouring enzyme activity
  • Promotes the precipitation of unwanted proteins in the kettle, hop back or whirlpool
  • Promotes yeast flocculation at the end of fermentation
  • Promotes head retention on beer
  • Reacts with oxalate to form an insoluble salt, preventing gushing in beer

SULPHATE (SO4–)
Sulphate is added to give beer a drier and more bitter effect

BICARBONATE (HCO3-)
Bicarbonate has the opposite effect to calcium in that it causes an increase in pH, so reducing the desirable effects of calcium

MAGNESIUM (Mg++)
Magnesium levels are typically rather lower than calcium and in addition its salts are more soluble,
so it has less effect on pH and flavour than calcium

CHLORIDE (Cl-)
High chloride concentrations are not usually found in water; its addition can impart palate fullness

WATER HARDNESS
Both temporary and permanent hardness can be treated using acidic products

WATER HARDNESS
The presence of calcium or magnesium ions in water gives rise to hardness, the familiar effect of which is to diminish or prevent the formation of soap lather. Calcium (or magnesium) bicarbonate in water is termed temporary hardness, so called because it can be removed simply by boiling the water and precipitating insoluble carbonate together with the evolution of carbon dioxide. Calcium or magnesium salts other than bicarbonates, typically sulphates or chlorides, are termed permanent hardness because they cannot be removed by boiling. Instead, other treatments such as sequestering, ion exchange are used.

Acid Treatment
This is now the most widely used method, for a number of reasons:-

  • It is relatively inexpensive
  • It is easy to use and does not produce sludge in the hot liquor tank
  • Products such as AMS will add desirable anions, sulphate and chloride
  • It can be achieved by using products such as Phosphoric Acid or Lactic Acid if no anions arewanted – for example in lager beers

It is essential to rouse the liquor when acid treating in order to encourage the removal of the carbon dioxide. This can have corrosive effects on the materials of construction of hot liquor tanks if left in solution.
