Another week, another new microbrewery opening in London. Plot all them all on a map, however, and you’ll see that there’s one central area with a glaring lack of local ales – Islington. But that’s all changing with the opening of the Hammerton Brewery, the first commercial beer producer in the borough since 1976 (bar a couple of brewpubs). Hammerton was originally founded in 1868, but closed in the 1950s; now, a descendant of the original brewers has begun fermenting, mashing and bottling under the original name (although in new premises, a railway arch off the Cally Road). Look out for the Islington unfiltered lager, the Pentonville oyster stout (made with real Maldon bivalves!) and the N7 New World hopped pale ale.
