The Golden Dawn, Auckland, New Zealand (thanks to Jacob Briars for the recipe!)
“A Dickensian marriage of gin, beer and ginger beer, and lemon, finished with outrageously good grapefruit bitters.”
Fill a beer glass with ice, add gin and beer, stir quickly, then top with ginger beer. Finish with 3 lemon wedges and a couple of dashes of Bittermens Hopped Grapefruit bitters atop the glass.
