Today, Mexico's best coffee is ripened and dried along the roadways in the cloud-blanketed highlands of Chiapas and over through Veracruz and Oaxaca. The prime beans are usually roasted a little darker than ours — almost a Viennese roast — and they brew a nice, medium-bodied liquid with some spunk. They tell me it's the second-class beans that get roasted darker, to a mahogany black with a shining sugar coat.
The steam-powered espresso machines in the city cafeterías extract a trio of ethnic brews: espresso, straight, foamy and Italian; café con leche, mixed with hot milk, French-style (but so common one would mistake it for purely Mexican); or americano, simply diluted with water. The more rural brew leans toward the Spanish, the history books say, but it seems like a Mexican-flavored campfire version to me. Café de olla at its best is pot-boiled in earthenware with molassesy piloncillo sugar and spices like cinnamon, anise or cloves. These days, many traditional city restaurants offer the dark, delicious drink more regularly, served in old-fashioned earthenware mugs at the end of the meal.
