Once the largest exporter of citron in the world, R&A de Jong (t787/829-2610), founded by Dutchman Andries de Jong in the 1960s, is now dedicated solely to the production of Café Bello, a high-quality coffee. Their plant is just north of town at PR-123 km 36.6 – you can stop to buy coffee and take a tour of the premises, but it’s best to call in advance if you can.
You can also buy gourmet coffee at Hacienda Patricia (t787/813-1878), home of the Segarra family’s sun-dried and wood fire-roasted Arabica beans. The plantation that was established in 1900, right on the Ruta Panorámica (PR-143 km 6.6, about 11km before Adjuntas – on the left just after the junction with PR-140). You can usually try their product in a small café on site.
