A lightly fermented, sweet drink from the State of Mexico. In the study's variety 1, toasted ground rice and spices are mixed with water and piloncillo (unrefined cane sugar), and a little pulque is added to start a 36–48 hour ferment in a clay pot. It is served at the Cabildo festival of San Martín Ocoxochitepec.

A lightly fermented, sweet drink from the State of Mexico. In the study's variety 1, toasted ground rice and spices are mixed with water and piloncillo (unrefined cane sugar), and a little pulque is added to start a 36–48 hour ferment in a clay pot. It is served at the Cabildo festival of San Martín Ocoxochitepec. Made in 4 steps over 36 h – 2 days. The longest step, start it with pulque and let it ferment, takes 36 h – 2 days (Quintero-Salazar B 2012). Pulque, the starter, carries Lactobacillus and Leuconostoc lactic acid bacteria, Saccharomyces cerevisiae and Zymomonas mobilis does most of the fermenting.
Modern sambudia is started with pulque and ferments for only 36–48 hours, with piloncillo, rice and spices. The 18th-century zambumbia was toasted barley in water fermented four or five days and sweetened afterwards. Fruit versions with pineapple or orange are, to some makers, really tepache.
Varieties 2 and 3No grain; water 62 %, piloncillo 25 %, spices and pulque 10 %, fermented 36–48 h.
Maize variety (4)Maize 15 %, cinnamon 3 %, water 52 %, piloncillo 20 %, pulque 10 %, fermented 48 h.
Pineapple-peel sambudiaIn El Oro made by fermenting pineapple peel; in Zacazonapan from Bromelia fruit with pineapple peel, maize leaf and ground maize (as cited by the study). Some makers call fruit versions tepache.
Safety
One maker told the study that strained sambudia keeps up to a month in a washed, closed bottle in the refrigerator, that straining removes what ferments it so it does not spoil, and that the bottle should be opened slowly because it foams a lot. She washes the bottle, treats it with Microdyn and rinses it.
A drink called sambumbia or zambumbia is recorded in New Spain in the 18th century. A 2012 ethnographic study found it still made in three communities of Ixtapan del Oro, most of all in San Martín Ocoxochitepec, where each new mayordomo brings a flower-decked clay jar of it to the Cabildo festival on the second Monday of Easter. Of the households that knew how to make it, 53 % no longer did.
