Learn Wine & Sommellerie in Napa Valley

The densest New World cohort of WSET candidates learns here, in a valley built entirely around the craft — classroom days and tastings in Napa itself, with the Diploma studied online and examined here.

The word is French. In Middle French a sommelier was the court official in charge of moving supplies, and the name probably goes back to the driver of a pack animal. The examined craft, naming a wine by its taste and proving it before examiners, was born in Britain: the first Master of Wine examinations were held in 1953, and the first Master Sommelier examination followed in 1969. London is still where its examiners are based. The Institute of Masters of Wine works from there, and since that first exam only some five hundred people have earned the title. In Bermondsey, the Wine & Spirit Education Trust, founded in 1969, saw 134,000 candidates take its qualifications in 2023/24.

Napa Valley, United States

Learn beside the densest New World cohort of WSET candidates, in a valley built entirely around the craft.

Season: Mar-Nov · Beginner -> Diploma / Enology

Three institutions, and the densest New World cohort of Diploma candidates — plus a university department, which means research sits beside the tasting room. A valley built entirely around one craft is the point here. ⚠ The growers' evidence on this craft belongs to Bordeaux, not to Napa.

What you walk away with

The credential that counts here

WSET Level 4 Diploma in Wines (and beyond, the Master of Wine / Master Sommelier title) · Certifying body: WSET (Wine & Spirit Education Trust) / Court of Master Sommeliers

That is the one an outside body sets and marks, which is what separates it from a certificate a school prints itself — that proves you attended. We name which of the two a course actually gives you; ask the school the same question before you pay, and judge the answer yourself.

Write me a note about this one — how you'd love to learn it, and where.

How a place gets on here, and what we do when it stops being true

There is a real difference between a school that teaches you and a good-looking website, and too much of the internet is the second kind. Four instruments do the work, and every one of them is visible on the page you are already on.

  • We grade it in public, and publish what is missing. The Measure is five plain questions, not a score: is there a teacher we can name, can a stranger get in, will you be learning beside other people, is the craft alive in the place, and is there enough there to keep you going for years. An empty dot tells you which one we could not answer and why. A craft nobody has graded shows no meter at all, because an absence is not a zero.
  • We print what we checked and did NOT list. Every swept craft carries the places we looked at and turned down, each with its reason. That list is the part no marketplace prints, because a rejection is where the money is.
  • The claims are read back to their sources every night. A robot re-reads every link we publish against the school's own page each night, and every price and course name we have written a test for. page. When one stops matching three nights running, it is flagged for a human — and an entry that cannot be confirmed comes off. It is never softened.
  • Where we are not neutral, we say so above the recommendation. We run one paid week a year, with one teacher. His entry says that before it says anything good about him, and prints the way to reach him without us, at his prices.
  • Nothing here has been stood in yet. An open sheet means desk research, carefully done. No place on this map has been visited and dated by us. When one is, the check will carry a name and a date — and until then, the grade says so in the dots it leaves empty.
  • Nobody pays to be here, and nobody can pay to be left off. No commission, no listing fee, no tourist board. The order is the strength of the community, never the size of the wallet.
Before you trust any school — mine or anyone else's — ask these five things
  1. Who actually teaches it? Can you find them by name, with a track record you can check yourself?
  2. Is the craft alive in that place, or is the school the only thing there? A real scene has more than one good option.
  3. What exactly do you walk away with — a recognised qualification, or a certificate they printed themselves? Ask which.
  4. Can you speak to someone who did the course? A real person, not a testimonial on their own page.
  5. What happens on a bad day — weather, an injury, a teacher who doesn't show? A serious place has an honest answer.

If a place dodges these, that's your answer. It costs you nothing to ask, and it tells you everything.

This is the short version. The full method is here — the six questions, in order, for any craft anywhere.
