Production & Heritage

On The Rocks partners with established spirit brands to create bar-quality cocktails in a portable format. The base spirit here is EFFEN Vodka, distilled from 100% wheat at Hooghoudt Distillery in Groningen, Netherlands — a facility with roots dating back to 1888. That wheat-derived softness is central to the blend, tempering the bitterness of the espresso coffee liqueur without diluting its intensity. The cocktail is formulated by professional mixologists, then blended and bottled in Texas. Unlike many RTDs that lean on artificial coffee flavoring, this expression relies on the interplay between a clean, neutral wheat vodka and genuine espresso character to achieve balance.

Tasting Notes

Aroma: Freshly brewed espresso leads immediately, followed by dark cocoa and roasted vanilla bean. An underlying sweetness rounds out the nose without overwhelming the coffee aromatics.

Taste: The entry is bold and coffee-forward, with dark roast espresso dominating the first impression. At mid-palate, the wheat vodka's creamy texture emerges, lending a velvety mouthfeel that balances the bitterness. A measured sweetness arrives toward the peak, recalling mocha and vanilla, though it never tips into cloying territory.

Finish: Clean and moderately lingering, with residual coffee warmth and a faint vanilla sweetness trailing off. The 20% ABV keeps the finish light enough to feel refreshing rather than heavy.

How to Drink On The Rocks Espresso Martini

Shake the bottle well and pour over ice, or serve chilled and strained into a coupe or martini glass for the classic presentation. This RTD is designed to drink as-is, but it also works as a cocktail building block. Use it as the base for an Espresso Martini Float by topping with a scoop of vanilla gelato for a dessert-style serve. Add it to a Black Russian riff with a splash of heavy cream and an extra shot of cold brew to amplify the coffee depth. It also blends naturally into a Tiramisu Cocktail — combine with a half-ounce of amaretto and a dusting of cocoa powder for an after-dinner drink that leans into the vanilla and mocha notes already present.

Best For

• After-dinner drinks when you want a polished espresso martini without the barware
• Hosting cocktail parties where consistency across servings matters
• Gifting a coffee-loving friend who also appreciates spirits
• Outdoor events, rooftop gatherings, or picnics where glass shakers and jiggers are impractical
