Art of Drink

Founded 2005 by Darcy S. O’Neil — a Canadian research chemist turned bartender who brought laboratory methodology to beverage development. Art of Drink is the primary methodology source for the Flavor Lab.

Career arc

Chemistry diploma — formal training in chemistry
Imperial Oil Research (Esso) — 7 years developing automotive lubricants
University of Western Ontario (UWO) — molecular pathology research
Laid off in 2005 during refinery downsizing — pivoted to bartending
Art of Drink blog (2005) — started documenting how to fix bad drinks at casinos and chain restaurants with a scientific approach
Historical discovery — found and digitized pages from an 1862 first edition of Jerry Thomas’s How to Mix Drinks, helping reignite historical cocktail interest
Fix the Pumps (2010) — self-published history of the American soda fountain with 450+ recipes; nominated for Best New Cocktail Book at Tales of the Cocktail 2011
Acid Phosphate and Lactart production (2010–present) — revived and manufactures traditional soda fountain souring agents from a rented commercial kitchen; 300–400 bottles of Acid Phosphate per month
YouTube channel — educational beverage science content; extraction, carbonation, formulation, sensory evaluation, safety
Flavor & Beverage Development Course — 6-module online course (Introduction, Safety & Regulations, Flavour Science, Creating a Flavour Aroma, Taste, Formulation Beverages)

Philosophy

“I still see myself as a scientist. I enjoy understanding how things work.”

O’Neil advocates for scientific rigor in drink-making: consistency, reproducibility, rigorous documentation, and proper methodology. He critiques pseudo-scientific bartending trends and promotes “buzz management” — creating complex low/no-alcohol beverages with aromatic compounds and esoteric ingredients as alternatives to standard mixers. His work democratizes flavor and beverage development knowledge that was previously limited to corporate laboratories.

Products

Product	Description
Acid Phosphate	Traditional soda fountain souring agent (phosphoric acid blend); does not influence flavor like citrus; the defining ingredient of a “phosphate” soda
Lactart	Lactic acid souring agent; milder, smoother sour flavor than citric; works in cocktails without excess sugar to balance
Soda Kit	Bundle: Acid Phosphate + Lactart + a copy of Fix the Pumps

Products available through the Art of Drink website shop.

Books

Title	Year	Notes
Fix the Pumps: The History of the American Soda Fountain	2010	450+ historical soda fountain recipes; nominated Best New Cocktail Book, Tales of the Cocktail 2011; ~100 copies/month sales; the foundational reference for the Flavor Lab

Relationship to the H&H project

Art of Drink is the methodology backbone of the Flavor Lab, and the connection to H&H runs deeper than technique:

Soda fountain history ↔ H&H’s era

Fix the Pumps documents the golden age of American soda fountains (1800s–early 1900s) — the same era in which H&H was founding and growing. The pharmaceutical origins of soda fountain culture (pharmacist-chemists making flavored carbonated drinks from extracts and essences) parallel H&H’s own extract-production practice. O’Neil’s revived Acid Phosphate is a product from this exact tradition.

Extract production methods

O’Neil’s percolation extraction method (the core technique for the Belfast Ginger Ale extract and other formulations) is the same pharmaceutical-grade technique H&H’s Spice and Extract Department would have used for their 33+ essences and extracts. The equipment is modernized but the chemistry is identical.

NA beverages and “buzz management”

O’Neil’s advocacy for complex non-alcoholic beverages aligns directly with the project’s beverages and flavor design direction — especially the ginger beer and ghost pepper ginger beer products, which are rooted in his Belfast Ginger Ale formulation methodology.

Ingredient overlap with H&H

The Flavor Lab’s ingredient inventory (vanilla, Ceylon cinnamon, nutmeg, ginger, orange peel, capsicum) maps directly to H&H’s documented spice and extract line. O’Neil’s formulations use these ingredients in the same tradition — botanical extraction for beverage flavoring.
