Densing gives bartenders a way to integrate oils into a drink without disturbing its basic structure. Philip Dizard, who owns Tin’s with his wife Mercury Tin, has applied the technique to the Dako-Ri Daiquiri, where olive oil adds roundness while lemongrass and Mao Jian tea sharpen the aroma.
The equipment is unusual, but the useful question is what changes in the glass. Densing can improve texture, preserve citrus notes and produce a more stable cocktail—provided the classic formula remains in charge.
What densing actually changes
A vacuum blender mixes ingredients while reducing the air inside its chamber. That helps prevent oxidation and produces a smoother, more consistent mixture. Densing uses this equipment to incorporate fat into a liquid without the binders or thickeners normally associated with emulsification.
The aroma benefit is particularly relevant to citrus cocktails. Citrus oil expressed over a drink may smell vivid at first but lose intensity as the glass is consumed. Integrating the oil directly into the spirit can keep that aromatic profile more consistent from beginning to end.
Appearance can change as well. Densing may create a cloudy, louche-like effect similar to the appearance of water added to absinthe or non-chill-filtered whisky. A Negroni, for example, can shift from bright red to a softer peachy pink. The effect is not universal; it depends on the ingredients and their proportions.
Texture is the more consequential change. McPherson, who developed densing and runs Panda & Sons in Edinburgh, Scotland, compares the result with fat-washing but says the vacuum-blended version captures and retains more aromas.
The technical line has boundaries
Densing requires control rather than a simple pour of oil into a shaker. McPherson recommends keeping the spirit, liquids and fat at roughly the same temperature, between 40 and 60 degrees Celsius, or 104 and 140 degrees Fahrenheit. He also suggests a fat content of approximately 0.5 to 2.5 percent.
The blender may require one cycle or two or three, depending on the mixture. With the right combination, the fat becomes fully incorporated, creating a unified liquid rather than a visibly separated mixture.
Those variables matter because a bar cannot treat densing as a decorative final step and expect every batch to behave identically. Temperature, fat percentage, agitation and pressure all influence the result. A vacuum blender can cost from $350 to $2,000, making the equipment a meaningful investment for a bar willing to standardize the process.
The Dako-Ri keeps the Daiquiri template
The Dako-Ri takes its name from Dako Tea, a shop Dizard and Tin visited during their honeymoon in Yunnan, China. Its remarkable tea service included tea, honey, lemongrass and aromatic local citrus.
Tin’s translated that memory into a Daiquiri built around fresh lemongrass-infused rum, Mao Jian tea syrup, fresh lime juice and olive oil. Rum, lime and sugar remain the recognizable base. Dizard allows himself some creative freedom, but he maintains the distinction between an adventurous drink and an actual Daiquiri.
Each addition has a defined purpose. Lemongrass contributes grassy brightness, while the tea adds a toasted, sticky-rice quality with a slightly savory finish. The olive oil supplies the rounded mouthfeel. Dizard also places the Dako-Ri on the sweeter side of the classic spectrum, believing that some excellent Daiquiris use a little extra sugar to achieve the intended texture.
For this cocktail, Dizard uses olive oil at one percent by weight relative to the infused rum. He runs three-minute agitation cycles with 30-second rests between them, reducing the chamber’s atmospheric pressure so the ingredients emulsify.
Our analysis: why the classic format matters
Densing offers bars a way to improve aroma, texture and batch stability without abandoning a recognizable drink. That distinction is what separates useful technique from novelty for its own sake. The Dako-Ri still reads as a Daiquiri first; lemongrass, tea and oil refine it rather than disguise it.
The operational case may be as important as the sensory one. Dizing says fat-washing might take 12 to 14 hours and can leave subtle residue, whereas densing takes about 15 minutes. The vacuum-blended emulsion is also more stable and does not separate as quickly, allowing Tin’s to make larger batches. Dizard reports that a test pint of dense rum remained unchanged after six months at room temperature.
| Approach | What Dizard reports at Tin’s | Practical trade-off |
|---|---|---|
| Densing | About 15 minutes; preserves the Daiquiri’s acidity; creates a stable emulsion | Requires a vacuum blender, temperature control and a carefully calibrated process |
| Fat-washing | May take 12 to 14 hours and can leave subtle residue | Slower preparation with a greater risk of residue |
The technique does not necessarily win every argument. Guests who prefer a lean, sharply acidic Daiquiri may find added oil less desirable than those who want a softer mouthfeel and more persistent aroma. For bars, the winners are likely those that can apply the method consistently enough to save labor, improve batch stability and refine several drinks rather than build a menu around a single technical flourish.
What to watch next
Watch whether more bars use vacuum blending as an everyday service tool. Tin’s already uses the blender to infuse olive oil into mezcal for its El Popular cocktail, and Dizard believes the equipment could reduce preparation time, refrigeration demands, storage space and labor for other bar teams.
The technique may also work beyond the Dako-Ri. Integrating oils into drinks such as a Martini or Old Fashioned could address the loss of citrus aroma while adding texture. Whether that becomes a wider trend depends less on the novelty of a vacuum blender than on whether guests can taste the difference.
For now, the Dako-Ri shows the central proposition clearly: a familiar formula can become more aromatic and rounded without losing its identity.
Key takeaways
- Densing uses a vacuum blender to incorporate oil into a drink.
- Temperature, fat percentage and agitation affect the final texture and stability.
- The Dako-Ri preserves the classic Daiquiri structure of rum, lime and sugar.
- Densing is most useful when it improves aroma and texture without overwhelming the original drink.
- The method can reduce preparation time and make larger cocktail batches more practical.
Frequently asked questions
What is densing in cocktails?
It is a technique for integrating oils into liquids with a vacuum blender. The aim is to improve texture and retain aromas without relying on binders or thickeners.
Who developed densing?
Iain McPherson, founder of Panda & Sons in Edinburgh, Scotland, developed the technique.
What is in Tin’s Dako-Ri Daiquiri?
It combines lemongrass-infused rum, Mao Jian tea syrup, fresh lime juice and olive oil while retaining the classic Daiquiri base of rum, lime and sugar.
How much olive oil does Dizard use in the Dako-Ri?
He uses a one-percent olive-oil proportion by weight relative to the infused rum.
Does densing make every cocktail cloudy?
No. It can create a louche-like effect, but the appearance depends on the ingredients and the process used for each drink.
