Small batch infused hand-made bitters. The 'Bob' of Bob's Bitters fame is actually a very talented pastry chef called Robert Petrie. Some years ago he started making his own infused sake under the brand name Nijizaki and this was eagerly received by many of London's top bars. Then encouraged by Giuliano Morandin of London's Dorchester Hotel, Bob started to make his own bitters. Bob's Bitters are now used in many of the world's leading bars.
