Bourbon Renewal

Crème de mûre is the closest, slightly less sweet and more jammy. Chambord works at 10 ml rather than 15, since it is sweeter and much more perfumed. Avoid anything sold as blackcurrant cordial or squash, which is sugar water with no alcohol to hold up the bourbon.

It is fruit and sugar, and it fades. Keep it cold and use it inside six months. After a year the bright currant snap has flattened into stewed jam and the drink turns muddy no matter what else you do. If the bottle smells dusty rather than tart, that is your answer.

Fifteen milliliters of cassis against 22 of lemon is the working ratio, and the 8 ml of simple syrup is a trim on top rather than the base sweetener. With a sweet supermarket cassis, drop the syrup entirely. With a tart Dijon bottling, keep it and taste before pouring more.

Better than a standard 40 percent. At 45 to 50 percent the whiskey has the shoulders to come through the cassis instead of sitting underneath it. A bonded bourbon at 50 percent or Wild Turkey 101 both hold their shape, and the extra proof takes the ice in its stride.

One large cube or a single rock. The drink can take dilution but not fast dilution, and a handful of small cubes will water it inside five minutes. Chill the glass in the freezer while you make it, so the cube is not doing the cooling on its own.

A classic Bourbon Renewal calls for 60 ml (2 oz) Bourbon, 22 ml (0.75 oz) Fresh lemon juice, 15 ml (0.5 oz) Crème de cassis, 8 ml (0.25 oz) Simple syrup, 1 dash Angostura Angostura bitters. That single-serve spec scales cleanly — the recipe above converts it to oz and multiplies it for 2–4 drinks.

A standard Bourbon Renewal is roughly 29% ABV once mixed (before ice melt softens it further). That makes it spirit-forward — closer to a Martini than to a beer, so sip it slowly.
