Depth Bomb

Calvados is the more delicate of the two, orchard-fresh and floral, and it lets the cognac lead. Bonded applejack at 50% is drier and pushes back hard, which some people prefer. Avoid blended applejack cut with neutral spirit, since it contributes very little.

You can, but then you are making a different drink: 20 ml of lemon with 15 of syrup turns this into something between a Jack Rose and a Sidecar. As written, the citrus is seasoning, there to lift both brandies rather than to make anything tart.

It tilts them. Bonded applejack carries more aroma per milliliter than a VS cognac, so 30 and 30 comes out apple-forward with the grape sitting underneath. To level them, take the applejack to 22 ml and the cognac to 38, or reach for a VSOP with more weight behind it.

Volume and company. In a Jack Rose the grenadine is the whole sweetener, 15 to 20 ml against a similar measure of lemon, and it has to balance real acid. Four milliliters against 60 of brandy cannot sweeten anything; it lends color and a thread of pomegranate tartness. Push it to 10 ml and the drink turns candied.

A classic Depth Bomb calls for 30 ml (1 oz) Cognac, 30 ml (1 oz) Apple brandy, 8 ml (0.25 oz) Fresh lemon juice, 4 ml (0.25 oz) Grenadine. That single-serve spec scales cleanly — the recipe above converts it to oz and multiplies it for 2–4 drinks.

A standard Depth Bomb is roughly 34% 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.

A Depth Bomb is shaken — the rule of thumb is to shake anything with citrus juice. About 13 seconds with plenty of ice chills and dilutes it correctly.
