In this episode, we're back with a fresh entry in our Rumcast Guides series — and this time we're taking on the rums of the United Kingdom!

Over the last 12 years or so, the UK has seen an explosion of domestic rum distilleries, with the number now reaching over 25 (and counting). We set out to taste a wide selection of these rums to get a sense of the emerging category's characteristics, standout bottles, and notable distilleries, encountering everything from straightforward crowdpleasers, to long fermentation, dunder-charged flavor bombs, to unique profiles we hadn't encountered before.

Following an overview of the category, the episode is divided into four flights that cover nine different distilleries and 16 different rums:
