Ruby port contributes rich wine notes to this Scotch whisky based cocktail with rhubarb amaro contributing complex bittersweet flavours. The Sun Tavern’s original spec calls for “oak bitters” but given its “Red” moniker we opted for Peychaud's Bitters.
Adapted from a drink discovered in January 2017 at The Sun Tavern, Bethnal Green, London, England which called for Nardini Rabarbaro Amaro instead of Cynar.
