What are the key takeaways from this Odd Lots episode?

Key insights include: **Guinness optimization:** Achieving a consistent pour requires controlling roughly 30 variables: keg temperature, pipe width, line length, gas mixture ratio, cooler temperature, and flow speed. The Devonshire uses a custom 82% nitrogen / 18% CO2 blend rather than the standard UK premix of 75/25, pours to the harp in 13-14 seconds, then rests 90 seconds on the font before topping off.; **Pricing power and volume strategy:** Rather than raising menu prices frequently, The Devonshire has adjusted prices only once across two and a half years of operation. The preferred lever for offsetting rising input costs is volume — when covers are high, margin pressure eases. Secondary levers include smarter purchasing, waste reduction, and small labor scheduling adjustments rather than passing costs directly to customers.; **Co-founder skill differentiation:** The Devonshire's three-partner structure works because each founder covers a distinct domain: one handles commercial and financial oversight, one manages food, sourcing, and kitchen systems, and one runs front-of-house operations and culture. Rogers advises against partnering with someone who duplicates your own skills, framing the ideal structure as three non-overlapping corners of a working triangle.

Key Takeaways

✓Guinness optimization: Achieving a consistent pour requires controlling roughly 30 variables: keg temperature, pipe width, line length, gas mixture ratio, cooler temperature, and flow speed. The Devonshire uses a custom 82% nitrogen / 18% CO2 blend rather than the standard UK premix of 75/25, pours to the harp in 13-14 seconds, then rests 90 seconds on the font before topping off.
✓Pricing power and volume strategy: Rather than raising menu prices frequently, The Devonshire has adjusted prices only once across two and a half years of operation. The preferred lever for offsetting rising input costs is volume — when covers are high, margin pressure eases. Secondary levers include smarter purchasing, waste reduction, and small labor scheduling adjustments rather than passing costs directly to customers.
✓Co-founder skill differentiation: The Devonshire's three-partner structure works because each founder covers a distinct domain: one handles commercial and financial oversight, one manages food, sourcing, and kitchen systems, and one runs front-of-house operations and culture. Rogers advises against partnering with someone who duplicates your own skills, framing the ideal structure as three non-overlapping corners of a working triangle.
✓Smoking ban as structural inflection point: The 2007 UK indoor smoking ban functioned as an economic earthquake for pubs, driving away older drinkers while opening the door to a younger demographic expecting cocktails and food. This shift directly catalyzed the gastropub model, which now spans a wide spectrum from casual food-serving pubs to near-restaurant operations, making the term "gastropub" functionally meaningless without further specification.
✓Scalable menu design: Dishes that work at 650 covers per day require measurable, step-by-step recipes that eliminate assumption and minimize error. The Devonshire splits cooking stages — a high-heat grill station creates the crust and sear, then a separate kitchen station controls final doneness — allowing throughput that a single-station approach could not achieve. Selecting year-round dishes eliminates seasonal menu changes and reduces cost volatility.

Selecting year-round dishes eliminates seasonal menu changes and reduces cost volatility.
•Pub licensing scarcity: In Westminster, pub licenses are location-specific and non-transferable. When a license lapses, it is permanently lost. Obtaining a new pub license in central London is rare enough that The Devonshire team spent years persuading the landlord to convert the former Jamie's Italian site — originally the old Devonshire pub closed in 2009 — back into a licensed pub before opening in November 2023.

Notable Moment

Rogers describes spending time in Dublin cellars before opening, studying every variable from pipe circumference to gas saturation, then building a proprietary Guinness system. He notes the process is still unfinished — a food scientist is due in June to investigate how gas solubility shifts as keg volume decreases throughout a service.

And I'm Tracy Alloway. Today, you're gonna be treated to a special two part episode. We are here in London, and so we wanted to learn about the business of pubs, of course. And so we're bringing you first an interview with famed publican Oisin Rogers. He is the cofounder of the pub, The Devonshire. And then in the second half, that will be an interview that was recorded live at a show that we're doing here in London with the chef at the Devonshire, Ashley Palmer Watts. Take a listen. You know, we've talked about this before. Some of my favorite episodes, and I mean this completely unironically, are when we talk to people in the food service industry in some way. Because I truly think that, you know, what we specialize in, which is sort of where the macro meets the micro, etcetera, there are so many whether it's labor cost, food cost, consumer sentiment, consumer appetites, etcetera. There are so many things that only someone in that specific industry gets a real view on at any given moment. No. Totally. Restaurants and food service in general are great microcosms Great microcosms. Macro trends. And so since we're in London, you know, a lot of the same restaurants, a lot of the same things, but, of course, there …
