Biodynamic | Organic | Sustainable

Every aspect of how we grow, process and roast arabica coffee is grounded in its effect on the environment. An organic lifestyle and a climate conscious business is our personal choice.

Red Caturra

Yellow Bourbon

Seedbeds and Nurseries

There are seven arabica varieties on our Pematang Purba farm, all of which were started from seed that was propagated from cherry. Our original farm in Mariah Dolok was red caturra. Lisa used cherry from this original farm to start the red and yellow bourbons now growing in Pematang Purba. Lisa maintains a plant nursery year round for farmers and new start ups. Some varieties are free and others are for purchase only. Visit the varieties pages for more information and the website shop to order.

Farm Selection and Preparation

Back Bay Estate is in the Barisan Mountain Range, in the Regency of Simalungun. No herbicides, just elbow grease was used to clear the land for planting. After clearing the land, Lisa developed a FOOTPRINT for the property with grids for the coffee and leguminous shade trees along with Fruit and Nut trees. Shade Grown Organic Arabica is sweeter and healthier. The birds and bees are everywhere on our farm. The Siamang Forest is full of life, we are dedicated to being good stewards of the forest and the land we call home. We began the process of having the property established as a wildlife conservation in 2022 in order to protect it for future generations.

Come stay with us, explore and learn about Sumatra, the unique coffees here and the seed to cup progression.

Planting and Crop Maintenance

Timing is everything. There are only two seasons in Sumatra; Rainy Season and Dry Season.  Lisa developed a program for using only organic composts and fertilizers to feed the coffee trees and other crops. By products from farm maintenance and coffee processings are used to make compost on site. Maintenance and form pruning  trees helps produce more coffee cherry fruit and extend the productive lifespan of coffee trees. To control pests, a natural organic pesticide is used. Beuvaria Basiana is sprayed on the green fruits to reduce the risk of  damage by the coffee berry borer insect. We also make these products available to farmers.

Harvesting and Processing

All of our arabica is handpicked. Only ripe cherry is harvested. Because conditions vary in each microclimate, and elevations too, harvest times and duration also varies. Having a full time, hands on operation helps us maintain the farm and manage the changing effects the weather has on our harvests.

We have a wet mill and a dry mill on our property that was selected as one of the “Best Design” submissions at SCA 2018 EXPO in Seattle. We have produced award winning lots of dry natural and also received a 90+ score from the Coffee Review in USA. Lisa was awarded the “Producer of the Year” award in 2018. A true farm to cup experience in one location awaits you. Contact Lisa for your booking or for an information packet at +62 08116010004 on WhatsApp
