Siren Partners with UK Roasters to Launch Four Coffee Beers

Siren Craft Brew has launched of a quartet of new beers that have been developed to highlight the diversity, intensity and personality of the humble coffee bean. Under the banner ‘Project Barista,’ Siren has collaborated with three UK-based roasters to create four distinct coffee beers:

  • Turkish Indulgent Imperial Stout with Coffee (10% ABV) is inspired by the country’s robust coffee traditionally served with a piece of rock candy. 45kg of Thai coffee beans, roasted by Reading’s Tamp Culture coffee, are added at three different intervals of the brew. The brew also includes the addition of vanilla and orange zest in the spinbot, orange zest and nutmeg in the whirlpool, and 420kg of figs to the fermented beer. The beer has smooth spicy notes, a nice citrus sweetness and a sound body. SRP £76.32
  • Americano Devious Double IPA with Coffee (9.1% ABV) is a Coffee Double IPA that uses a debut method designed to preserve the delicate nature of this natural coffee’s high-end berry notes. Quarter House Coffee in Birmingham brewed a strong hot coffee using 17kg of natural Ethiopian coffee which was added to the beer directly before packaging. Americano features Citra, Columbus, Cascade, Chinook hops, and Mosaic Cryo Powder, to the tune of 21 grams per litre. SRP £65.76
  • Crema Deceptive Sweet White Coffee Stout (4.9% ABV) is a German Whiskey Barrel Aged Coffee White Stout that builds on two of Siren’s other aged beers: Black Light Banana and Bourbon Coffee Broken Dream. Siren steeped Tamp Culture’s coffee in a fermenter at both 21°C and 0°C to accentuate the low notes of the coffee, whiskey, wood, vanilla. Cocoa nibs and vanilla were then added to 25kg of German Whiskey Aged Coffee to create a beer that enriches the character elicited from ageing the green beans in barrels. SRP £35.28
  • For CapHeine Kettle Sour with Coffee (6.2% ABV) Siren paired with artisan coffee roaster Climpson and Sons in London to deliver a kettle sour beer. The most nuanced coffee beer of the four, CapHeine’s biscuit, bready malt notes utilise hibiscus and raspberries along with a floral and fruity Kenyan coffee bean to create a cacophony of flavour. There are notes of redcurrant, cranberry, plum, red fruit and some light hibiscus florals. Mosaic, Palisade and Bravo hops are added during kettling and as a small dry hop addition. There’s hibiscus in the boil, and 120kg of raspberries were added to the fermentation. SRP £40.68

Traditionally craft beers are somewhere between 5-6% ABV so these beers have a slightly higher ABV. Launched in July, Siren’s Turkish, Crema, Americano and CapHeine on draft at six sites across Britain and in bottles at online retailer Honest Brew ( Siren plans to release the coffee beers annually.

Siren Craft Brew has been included in Ratebeer’s ‘Top 100 Brewers in the World’ for the third year running and has undergone recent expansion at their home in Finchampstead, Berkshire.
