Network of substrates. Capital letters in the grey circles represent the TMFB, the size of circles and letters are related to the number of substrates employed; the letters without circles represent the species employed in fermentation, their size represents the number of uses in different fermented beverages. The M and P clusters are related to the substrates used for preparing mescal and pulque, respectively; the A represents the Agave species employed. The A in the middle of pulque and mescal cluster represents shared species, while in the external position represents exclusive agave species. The C circle is the colonche production, it is prepared with several cacti fruits, and shares A. salmiana for its production as other beverages in which the A is in the center of the network. The centered cluster is related to maize produced beverages (pozol, tesgüino, tejuino, atole, chorote, saká) in which Z. mays (Z in the middle) is the core substrate for these fermented beverages. The B cluster is the balché group, in which L letters refer to Lonchocarpus spp.; the T cluster is related to beverages prepared mainly by the fermentation of palm sap such as taberna and tuba. Species and beverages are listed in the Table S1. Illustration credits to Rosa Jeannine Xochicale Solís.
