Cooper Union
Irish whiskey and elderflower, with a smoky secret
The Cooper Union is a study in what happens when smoke is used as atmosphere rather than flavor. A standard Islay rinse coats the glass with peated whisky, then the whisky is discarded. Only the volatile aromatic compounds remain, clinging to the glass walls. The cocktail poured into that glass never touches peat directly. The peat only appears in the nose and the finish.
The cocktail itself is soft: Redbreast 12, an Irish single pot still whiskey, rich and entirely unpeated; St-Germain elderflower liqueur, floral and light; dry vermouth for structure and length. These three together make a gentle, aromatic stirred drink that would read as delicate without the rinse. With the rinse, every sip arrives through a smoke signal that the ingredients themselves know nothing about.
It is a complete drink built around an absence. The most present ingredient is the one that was poured out.
Freezer-Door Batch (1L)
Batch the whiskey, elderflower, and bitters. Rinse each glass fresh with peated Scotch at service — this step cannot be pre-batched.
Notes on Batching
The rinse is essential — it cannot be pre-batched. Keep a bottle of Laphroaig or Ardbeg at the bar. The smoke coats the glass and transforms every sip. Without the rinse this is a different, lesser drink.
Single Serve
Serve without ice — this drink is meant to be sipped at room temperature. The smoke rises from the glass as it warms.
Why This Drink Exists
Phil Ward created this drink to demonstrate how a rinse can transform a cocktail's identity without altering its composition. The Irish whiskey and St-Germain never directly contact the peat — the smoke lives in the glass, in the vapor, in the finish.
Redbreast 12 is a single pot still Irish whiskey — a style unique to Ireland, made with both malted and unmalted barley. It has a fruity, spicy, almost orchard-like character that pairs naturally with elderflower's lychee-and-pear floral notes.
St-Germain at 1/2 oz is quiet but present. It keeps the drink from feeling austere — just enough sweetness and floral quality to give the Irish whiskey something to lean against.
The Flavor Arc
What Each Ingredient Brings
Redbreast 12 Irish Whiskey
Single pot still Irish whiskey from the Midleton Distillery. Pot still style uses unmalted barley, creating a spicy, creamy, fruit-forward character distinct from Scotch or bourbon.
Why Irish: the pot still style has enough presence to hold St-Germain without being overwhelmed, and enough fruit to accept elderflower as a complement.
St-Germain Elderflower Liqueur
Made from freshly handpicked elderflower blossoms — the harvest window is two weeks per year. Flavor: lychee, white grape, pear, floral.
The floral quality pairs with Irish whiskey's fruit character. At 1/2 oz it whispers rather than shouts.
Peated Islay Scotch Rinse
Laphroaig (heavily peated, medicinal, maritime) or Ardbeg (less medicinal, more complex) both work. The rinse uses less than 5ml — the flavor comes from the residue coating the glass.
This is the drink's signature. The smoke doesn't dilute or alter the cocktail — it exists in the glass walls, rising with each sip.
Variations to Explore
Heavier Rinse
Use more Scotch in the rinse, or use a higher-phenol expression like Octomore. The smoke becomes a structural presence rather than a hint.
Honey Instead of St-Germain
Sub 1/4 oz honey syrup for the elderflower. Warmer, less floral, more traditional Irish whiskey territory.
Jameson Black Barrel
Sub Jameson Black Barrel for Redbreast. More accessible, sweeter, with more bourbon barrel influence. Less complex but equally valid.
