Almost everyone who comes to San Francisco looking for chocolate goes to Ghirardelli Square, and almost nobody who does gets what they came for. Ghirardelli does not run a factory tour in the city. Some of the original chocolate-making equipment is still there as a display, which is a genuinely interesting piece of industrial history and not the same thing as watching chocolate being made. The working craft factory people actually want to see is about three miles inland, in the Mission.
The tour worth doing books out months ahead and the one everybody assumes exists does not run at all, which is an easy afternoon to waste. Tell Karpo when you are free and how many of you there are, and get the tastings that are genuinely bookable in that window.
Dandelion is the one that actually runs
Dandelion Chocolate's factory occupies a century-old brick building on 16th Street, and the tour walks you through the full production line with a chocolate educator — from fresh cacao pulp, which almost nobody outside the industry has ever tasted, through to the finished bar. It runs around fifteen dollars, operates about four days a week, and books up months in advance.
That last detail is the one that ruins afternoons. This is not a walk-up attraction. If you are visiting the city for a specific week, book the tour before you book anything else flexible, because the calendar does not open up close to the date. If you have missed it, the factory's retail and café space is open regardless and the tasting flight there is a reasonable consolation.

The rest of the map, honestly
TCHO used to run a genuinely good factory tour from Pier 17. It moved production to West Berkeley, tours have been hinted at in the new facility and have not materialised in any dependable way. Treat it as unavailable unless you have confirmed otherwise directly, rather than building a day around it.
Guittard, in Burlingame, has been making chocolate since 1868 and is one of the oldest continuously operating American chocolate makers — but it is a wholesale operation, not a visitor attraction, and it is on the peninsula rather than in the city. The broader point is that the Bay Area's chocolate industry is real and mostly industrial, and the number of places where a member of the public can watch it happen is very small.
What a tasting is actually teaching you
A proper flight is organised by origin, and the reason it works is that single-origin dark chocolate varies more than most people expect — a Madagascan bar reads bright and red-fruited, an Ecuadorian one floral, a Tanzanian one sharp and almost sour. Tasting them side by side in one sitting is the only way the differences become obvious, which is why a flight teaches you more in twenty minutes than a year of buying bars one at a time.
Eat them lightest to darkest, let each one melt rather than chewing it, and drink water rather than coffee between them. Coffee is served alongside chocolate constantly and it flattens exactly the acidity you are trying to notice.
Making a Mission afternoon of it
The factory sits in the middle of one of the densest eating neighbourhoods in the city, which makes the tour a good anchor rather than a destination in itself. A late-morning tour, lunch within a few blocks, and a slow walk through the Mission afterwards is a better use of the booking than treating it as a standalone errand — particularly because the tour ends with enough chocolate in you that you will not want dessert for several hours.
Practical notes
Ghirardelli does not run a factory tour in San Francisco — the equipment at the Square is a display. Dandelion's 16th Street factory tour costs around $15, runs roughly four days a week and books months ahead, so reserve before anything else on your calendar. TCHO moved to West Berkeley and its tours are not dependable; Guittard in Burlingame is wholesale and not open to visitors. Taste lightest to darkest, let each square melt, and drink water rather than coffee between them.
What to buy if you skip the tour
A factory tour is a good afternoon and it is not the only way in. Buying three single-origin bars from the same maker at the same cacao percentage is the cheapest possible tasting flight, costs about the same as one cocktail, and teaches you the same lesson — that origin does more work than percentage does.
Percentage is the number everyone fixates on and it is the least informative thing on the label. A seventy per cent bar from one origin can taste sweeter than a sixty-five from another, because the number describes how much of the bar is cacao rather than how it tastes. Read the origin and the maker first; treat the percentage as a rough guide to intensity and nothing more.
