Each month, Gin Explorers will receive 4 bottles of different gins. Each bottle contains 50ml so the box contains enough for 8 normal measures of gin and tonic. You'll also receive a selection of mixers plus some bonuses and surprises. Past goodies have included bar spoons, gin infusion kits and cocktail ingredients. Every box also comes with a map, showing you the provenance of that month's gins as well as giving tasting notes and digging into the history of each brand.
