The San Andres Tuxtla valley in Veracruz, Mexico, one of the oldest continuously farmed tobacco zones in the Americas. Its Negro San Andres leaf is thick and dark and is used chiefly as madurowrapper and as flavoring filler.
Why it matters
San Andres has become the default madurowrapper for many non-Cuban brands because it ferments to a deep color while keeping an earthy, cocoa sweetness.
In context
"The San Andres wrapper on that robusto gave it a dark cocoa and soil character from the first inch."
