London Beer City

Fundamentals #10 – Brew By Numbers/Hop Burns & Black 55|05 Double IPA Citra & Ella

This week has been all about London Beer City and the crazy amount of events book-ended by the London Craft Beer Festival and the Great British Beer Festival. As ever when there’s a glut of beer events pace is the trick but with so much good beer flowing this gets tougher every year.

At the heart of this year's London Beer City schedule is the Battle of the Beer Shops. The event will see a series of collaborations between a selection of London’s specialist beer retailers and some of the city’s craft breweries. At the time of writing this piece it takes place tonight, so keep an eye on your favourite social media channel to keep up with the fallout.

For their beer, the folks at HB&B have teamed up with the ever-verdant Brew by Numbers and, as they also did recently with Marble Brewery, have produced a Double IPA.

Brew by Numbers has grown increasingly deft with the production of hazy and hoppy beers over the past few months and this effort fuses US Citra and Aussie Ella hops with lemon zest to produce a citrus and tropical fruit blast wave of flavour. These fruit notes are paired with a typically soft and pillowy mouthfeel that has become the hallmark of Brew By Numbers’ beers.

I was surprised, however, to learn that the yeast that fermented out this beer was the humble Safale US-05. This fundamental is at the heart of many a great beer but with the recent trend in yeasts that produce rich, stone fruit flavours in hazy IPAs I wasn’t expecting Brew by Numbers to tell me that this was the yeast at play in this beer.

US-05 provides an exceptionally clean fermentation, meaning that it produces very low amounts of esters, which are responsible for the peach and apricot notes in a lot of modern “New England” style IPAs.

Brewers rely on clean fermenting yeasts like US-05 to let hop notes shine through, which in a beer such as this Double IPA is essential. Clean yeasts such as US-05 are often unsung heroes when it comes to beers like 55|05, so be sure to tip your glass in affection to this workhorse of a yeast strain when you enjoy this beer.

The fundamentals of beer are anything that makes up the sum of a beer’s parts. You can find more from beer writer Matthew Curtis at his excellent beer blog Total AlesGood Beer Hunting and on Twitter @totalcurtis. Pick up some of our amazing 55|05 collab in store or online while stocks last.
