Yup. Haven't tried with bitters yet. I've tried that brand of ginger beer once on vacation, but can't get it around here. I opt for Goslings when I can get it and otherwise try the other varieties available locally when I can't. Sadly, this drink really does depend on the ginger beer - the profile can change drastically depending on which brand you use. Goslings seems to work the best with the most varieties of rum - theirs or other spiced/black rums.
