02STRAIN INTO A FLUTE
03TOP WITH CHAMPAGNE
04FLOAT ISLAY SCOTCH ON TOP
1 oz taken as 30 ml in the metric column.
STRENGTH // WORKED
Pre-batch
2.67 oz mixed with ice, 0.67 oz of it pure alcohol
Melt
Shaken: +20 % of the pre-batch, +0.53 oz of water
Topped
Poured after the melt, kept whole: champagne 2.5 oz, +0.3 oz of alcohol
Served
2.67 + 0.53 + 2.5 = 5.7 oz in the glass, 0.97 oz of it alcohol
Strength
0.97 ÷ 5.7 = 17.0 % ABV as served
Ethanol
0.97 oz × 29.57 ml × 0.789 g/ml = 23 g · about 158 kcal from the alcohol alone
IN THE GLASS
VANILLIN
FROM BLENDED SCOTCH · from oak barrel aging
Formula

Mass
152.15 g/mol
IUPAC
4-hydroxy-3-methoxybenzaldehyde
Bourbon's fingerprint, extracted from the charred American oak the law requires for aging. Same molecule as the vanilla bean's signature, so a well-aged bourbon legitimately tastes like vanilla. Chemistry, not metaphor. Cognac, aged rum, tequila reposado all extract vanillin from oak too. Different barrels, same molecule.
The smoke molecule. In peated scotch from burning peat over the malted barley; in mezcal from the underground roasting pit; in barbecue, smoked paprika, and bonfires. One molecule covering campfire, Islay whisky, and good carnitas. The brain files all three under "fire."
The dominant acid in grapes and the reason wine tastes sharp instead of flat. Forms crystals ("wine diamonds") when bottled wine gets cold; harmless, sometimes filtered out, sometimes left in as a mark of authenticity. Without acid, wine is sugar water.
Penicillin with Champagne. It is the Sam Ross Penicillin elevated: Champagne's CO₂ amplifies the Islay float's guaiacol and phenol signature. It works because the Islay, poured gently last, is lighter than the sweetened drink beneath it, so it floats rather than mixes.
PROVENANCE
An invented variation on Sam Ross's 2005 Penicillin (Milk & Honey, NYC; already in this catalog). The champagne addition came out of various craft bars through the 2010s as the spritz-everything trend hit the Penicillin template. The Islay float's behavior is the technical achievement: Islay scotch's lower density (40% ethanol and no sugar, against the sweetened drink) lets it sit on top of the champagne for several minutes if poured carefully.
