Indonesian Coffee Brands | How to Enjoy Indonesian Coffee | Introduction to Java Frinsa Estate

Java Frinsa Estate

Wildan Mustof owns this estate. In 2010, he and his wife Atieq started their first coffee-growing plan in the Sindangkerta Weninggalih area. After that, the Java Frinsa Estate farm became their main growing area. From the first year of production, Wildan focused on quality, requiring strict management and processing methods. While most Indonesian producers were using the wet-hulled method, Wildan focused on fully washed processing. This coffee is the Sigarar Utang variety cultivated by Frinsa Estate. Frinsa Estate sits at an altitude of 1300-1600m and covers about 110 hectares in West Java (known locally as "Sunda"). At 1400m they run a wet processing plant, a well-ventilated storage space, and a drying facility, which means they can fully control product quality from harvesting and grading through screening and shipping. Most of their coffee is fully washed, though they also do some wet-hulled and natural processing, mainly for the local market. They classify lots by planting location, variety, and harvest date. Working with coffee research centers, they have divided the farm into zones to plant many different unknown varieties; because the trees are still small, no one yet knows what flavor profiles they will present. Beyond their own production, they also process coffee for local smallholders.

The harvest season runs from May to September, with the main harvest from June to August. After harvesting, the coffee is sorted by hand to remove unripe and pest-damaged cherries.

Once the harvested berries are pulped, they first undergo 15-18 hours of dry fermentation, then water is added for a further 10-12 hours of fermentation. After fermentation is complete, they are washed clean with fresh water.

At present, most coffee is first dried on racks in a greenhouse for 1-2 days, then moved to a patio to finish. Drying takes about 14-20 days, depending on whether it rains during the period.

FrontStreet Coffee Recommendation

Indonesia's coffee is defined by body and depth, and Frinsa's fully washed approach is one expression of it. For the classic version of the Indonesian profile, the FrontStreet PWN Golden Mandheling is sorted three times by hand plus once by machine to remove defects, leaving large, even, translucent beans; medium-dark roasted, it delivers sandalwood, herbs, spice, roasted hazelnut, caramel, and dark chocolate with a clean, mellow finish. If you brew mainly espresso, the FrontStreet Classic Blend is an oil-rich traditional Mamba recipe built for espresso machines and moka pots, with butter, nut, spice, dark chocolate, and toast notes and a full, rounded body.
