From the foundation website:

The Heart Land of the Olmecs is the tropical lowlands of modern-day Mexican states of Veracruz, Tabasco, and San Andrés Tuxtla. Today, this is the same region that grows some of the finest San Andrès Negro wrapper tobacco.

This seed variety is considered one of the oldest seed varieties in the world. Olmec cigars contain the finest Nicaraguan filler tobaccos from the Esteli and Jalapa valleys. After fermentation, these filler tobaccos are bale aged for three years before arriving on the production floor.

The San Andrés Negro wrapper tobacco comes from the rich volcanic soil of the land of the Olmecs. It is fermented slowly at low temperatures to preserve the natural oils that give flavor. The blend delivers a full-bodied smoking experience with rich flavors of cacao, dark espresso, and spice without being too aggressive.

As soon as I decided I liked them, every place went OOS for them. Damn cigar fairies be stealing all my treasures.

Each to his own.

I recently attended a Foundation Cigars event. The rep said the Tabernacle was their most successful launch until Olmec. He said the Olmec is doing double the volume in first few months of release compared to Tabernacle. I do find it a bit pricey though, seems like no matter which vitola they’re around $14 MSRP.
