|1 1⁄2 fl oz||Bourbon whiskey|
|5⁄6 fl oz||Freshly squeezed lemon juice|
|1⁄2 fl oz||Sugar-free sweetener|
|1 dash||Angostura or other aromatic bitters (optional)|
|3⁄4 fl oz||Claret red wine|
The splash of Claret wine makes this cocktail – both in terms of flavour and visually. Adding the aromatic bitters will help the flavour but also adds trace amounts of sugar.
