Hammerton was one of the many British breweries that bit the dust during the 1950s and '60s as the industry indulged in a disastrous bout of consolidation; it came back in 2014, albeit on the wrong side of the river. The new brewery even brews an oyster stout, as the original Hammerton did. Look out for N7, the beer developed in partnership with James Kemp, formerly head brewer at Marble and Buxton and now weaving his heavy metal magic for Yeastie Boys.
