The world's cleanest cup of coffee

A lovely long read from Mashable on the return of sailing cargo ships to transcontinental trade. The Avontuur is a 97-year-old sailing ship that is aping the Tres Hombres, which brings chocolate and rum from the Caribbean to Europe. This absorbing account details the huge problems facing the wind-assisted cargo shipping industry, as it follows the Avontuur on its maiden voyage from Honduras to the German port of Bremen with a consignment of premium coffee. One of the major disadvantages is cost: $3,700 in a container compared with $43,000 on the Avontuur… emission-free transport comes at a hefty price.
