Switzerland is synonymous with chocolate and it comes as no surprise that the world’s oldest chocolate maker Cailler is arguably also the world’s best. In ancient times, chocolate, once considered the “elixir of the Gods,” was believed to have magical properties. I agree.

No trip to Switzerland is complete without sampling one the nation’s finest offerings, yet I never toured a chocolate factory until my niece came for a visit. Boy, was I missing out. A trip to a chocolate museum entertains all ages. It is worth it just for the free samples.

The most well known of Swiss chocolates, Cailler claims to be the oldest brand. Cailler produced chocolate in Vevey as far back as 1819 and since 1889 in neighboring Broc where today millions of tourists visit the La Maison Cailler du Chocolat. In 1929 Cailler became part of the Nestle group, but it still functions independently.

The Swiss consume the most chocolate in the world. 5% prefer white, 20% prefer dark and 80% prefer milk chocolate, which is made from treasured 200 year old Swiss secret recipe. In my opinion the darker the chocolate the better and apparently experts agree the higher the cocoa content the better it is for your health.

In 1911 Alexandre-Louis Cailler developed a different process to manufacture a creamier, milky flavored chocolate. Instead of using powdered milk, he took condensed milk from Alpine milk in the Gruyère region to create a milk chocolate with an incomparably smooth, rich milky flavor. To this day, Cailler is the only Swiss chocolate manufacturer to use this method.

While you wait your turn to enter the museum, you can watch through windows where on the floor below the chef leads a class of visitors in making 5 different kinds of chocolate in the chocolate workshop.

For 12 Swiss francs, visitors enter the museum’s historical journey of chocolate’s development through time in multi sensory audiovisual tours. Chocolate originated in antiquity from Mexico’s cocoa bean. In the 1500s, Spanish conquistadors brought chocolate to Europe where it was considered taboo until the pope declared it a wholesome drink. In the last century, the French considered it an aphrodisiac and savored tiny cups of divine chocolate silk while in bed.

As part of the Maison Cailler experience, you are allowed to touch the cocoa beans, butter, nuts and raw material used to make chocolate. A replica of the conveyor belt used in the factory shows the process of how Cailler’s signature Mini Branches – hazel nut filled logs – are made, cut and wrapped.

The highlight for any sweet tooth is the free sampling at the end. Just like at a chocolate shop, every sort of bar and cream filled chocolate align the glass counters for free sampling from the sweetest to the most bitter. I skipped the white and milk chocolate varieties and made a beeline for the end of the row to savor the dark chocolates. My niece and her friend tasted a piece of every kind of chocolate except the dark ones.

After the tour, you can savor chocolate-based drinks and desserts in the café. You can also shop for brand souvenirs and Cailler chocolate bars, pralines and famous brands of Femina, Ambassador, and Frigor.

The only problem with unlimited sampling, a gourmet may suffer from what the French call a “crise de fois,” a liver crisis brought on by too much rich food.
