1/4 ounceblack currant liqueur (a.k.a. crème de cassis, optional)
A pint of this beer cocktail goes down so easily that some bartenders and pubs in the UK refuse to make it. Rumor has it that even former president Bill Clinton was denied at an English pub when he tried to order one with his lunch. The best thing about making a Snakebite yourself is that no one is going to stop you from having another. But proceed with caution.
Pour the cider and beer into a chilled glass, layering the lager on top of the cider if desired by holding a spoon over the glass and slowly pouring the lager over the back of the spoon. Top with the blackcurrant liqueur, if using.
