With the number of London breweries just about cresting the half-century mark, and many of them taking a greener approach to the amber nectar, we though it high time to put together a proper map. Click on a marker for notes on each and every brewery (correct at the time of typing - but seems new operations are churning out their debut batches every other week!). We've made a point to highlight breweries' sustainable, ethical, or community-focused initiatives.Yellow markers indicate brewpubs; green dedicated breweries (though some of these may have tasting bars or weekend opening hours).Got any additions or quibbles to make? Cool new brewery opening up the street? Tweet us at @jelliedeelmag or email firstname.lastname@example.org!
