The A Priori compounder at a vineyard event

Made one bottle at a time. Not by committee.

The wedding favor your
guests will actually keep.

We bring a robotic perfume compounder to your event. Each guest takes a quiz on their phone. The machine dispenses a 1‑of‑1 fragrance into a glass bottle with your label. Two minutes per guest. 150 guests, 150 bottles. None alike.

The N of 1 Protocol

No menu of bottles.
One made for each guest.

01

The Inquiry

Guests scan a QR code. They answer a short quiz on their phones — written for your event, your couple, your inside jokes. Less survey, more tarot reading. No apps. No downloads.

02

The Synthesis

Their answers become a personal scent direction. Fresh, warm, floral, smoky, soft, strange, polished — the blend is made for the person standing at the table.

03

The Manifestation

The compounder dispenses the recipe drop by drop into a glass bottle with your label. Two minutes. One bottle. Zero duplicates.

The Quiz

A short quiz. Written for your crowd.

Every quiz is custom-written for your event. Questions reference the couple, the venue, inside jokes — whatever makes your guests laugh and lean in. Your branding, your names, your story. Their answers become a scent they can watch being made, but the experience feels entirely yours. No A Priori branding on the bottles — just your event, your label, your keepsake.

The Experience

The hour between ceremony and dinner just got interesting.

Your guests have a drink in one hand and 45 minutes to kill before dinner. They gather around the machine instead. They take the quiz. They watch the robotics work. They walk away with a bottle no one else will ever own. By the time you sit down to dinner, half the tables are smelling each other’s bottles.

A Priori N of 1 bottle with custom scent label

Your label. Your event. Every bottle shows the guest’s name, their scent name, and your custom branding — “The Smith Wedding, Napa Valley — May 2026.”

FAQ

Common questions.

How much space does the machine need?

About the footprint of a small cocktail station — a standard 6-foot table is more than enough. We bring everything and handle setup.

Do you provide an attendant?

Yes. Every booking includes a dedicated A Priori attendant who runs the machine, guides guests through the experience, and handles any questions.

What if a guest has allergies or sensitivities?

Full ingredient list is printed on every bottle. Guests can flag any ingredient to exclude before their scent is made.

How long does each bottle take?

About two minutes from quiz completion to finished bottle. Multiple guests take the quiz simultaneously on their own phones, so there’s never a long wait.

What do guests take home?

A 30ml glass bottle of their 1‑of‑1 fragrance with your custom label — guest’s name, scent name, and your event branding. It’s a keepsake that looks like it came from your event, not from a vendor.

Can you customize the quiz for our event?

Absolutely — that’s the point. We design the quiz around your event: references to the couple, the venue, inside jokes, whatever makes it feel personal.

Is your branding on the bottles?

No. Every bottle is fully white-labeled to your event. The label carries your names, your venue, your date, and the guest’s scent. The brand is entirely yours.

Do you travel outside the Bay Area?

Yes. We’re based in Marin County and primarily serve the Bay Area, Napa, and Sonoma, but we’re available for destination events. Reach out and we’ll make it work.
