As you’re swigging on your favourite festive beer, have you ever wondered how they make it taste so good? Bess Browning visits Shepherd Neame brewery to discover the step-by-step guide of making their Christmas Ale.
Shepherd Neame’s headquarters in Faversham is probably one of the best places in the UK to discover how beer is made because it holds the title of Britain’s oldest brewery.
They brew dozens of varieties of beer and millions of pints are poured every year, but it’s not a simple process to get it from the hop to your glass.
The Christmas Ale is a limited edition and contains ingredients pale malt, crystal malt, target hops to add to the bitterness, Hallertau Hersbrucker hops also for bitterness and Styrian Goldings hops for that aroma which makes you feel instantly festive.
With scents reminiscent of raisins, dates and molasses, with tastes of malt and toffee, it is the perfect Christmas brew.
Ten steps to creating a heavenly brew
1 The malted barley is milled through Shepherd Neame’s original 1920s Four Roller Bobby Mill to create grist. The aim is to crush the grains to expose the starchy centre of the barley seed whilst retaining the husk as a large fraction for the separation process.
2 The grist is mixed with hot water (known as ‘liquor’ in brewing) via a copper Steel’s Masher to create a mash in a large vessel called the Mash Tun. The heat from the liquor activates the enzymes in the barley, which then begin to convert the starches in the grains into sugars during the single temperature infusion mashing process at precisely 63°C. This results in sweet wort.
3 The Mash Tun has a false bottom, which allows the sweet wort to be drained away from the grist to a large tank known as a brew kettle or ‘Copper’. Spargingis undertaken, the process where water is added to ensure the grain’s fermentable sugars are transferred to the Copper.
4 The sweet wort is boiled in the Copper. The boiling process sterilises the beer. Early in the boil the Target Hops are added by hand to give the full bitter flavour of a classic ale, as the boiling isomerises the alpha acids in the hops, creating the bitterness. At the end of the boil, lashings of Hallertau Hersbrucker hops are cast into the Copper to provide the spicy hop aroma.
5 The hops are removed from the bitter (hopped wort) in the whirlpool, going to the Wort Cooler.
6 The hopped wort is moved to a Conical Fermention Vessel and Shepherd Neame’s unique yeast is added to begin fermentation. As the yeast eats the sugars created during the mash, it expels carbon dioxide and alcohol, as well as producing a variety of flavour compounds, including higher alcohols and esters.
7 The beer is moved to a draught tank where Styrian Goldings hops are added to complement the complex spicy hop flavours of Christmas Ale.
8 The beer is racked into casks, where it ferments for a second time. Finings are added to help drag the yeast to the bottom of the cask and give a clear beer. Casks come in a number of sizes, but typically contain nine gallons of beer, equivalent to 72 pints, known as a Firkin.
9 The casks are sealed and delivered to pubs around the country. The brew needs to continue secondary fermentation in the cellar before it ready to serve. The landlord will knock a soft spile (small wooden peg) into the shive (broad bung hammered into a hole) on the side of the cask to allow the gas to vent.
The soft spile will be replaced with a hard one which doesn’t let air in or gas out, and
the beer is left to settle for 24 hours.
10 A tap is knocked into the end of the cask and the pub’s bar staff pump the beer up to the bar area via beer lines, using a handpump. The customer enjoys a delicious pint of Christmas Ale.
