indonesia + sumatra coffee
by quantum coffee roasters · cardiff, uk
you'll taste red apple before caramel. this is sumatra (indonesia) - mandheling, permata gayo, an indonesia + sumatra from quantum coffee roasters.
expect earthy and herbal base notes with sweetness from caramel, milk chocolate, and dark chocolate, plus a subtle red apple brightness. the overall profile leans rich and full rather than fruity or acidic.
this coffee is grown in sumatra, indonesia, using the bourbon varietal. sumatran coffees are commonly processed via wet-hulling, a regional method that strips the parchment while the bean still carries moisture, contributing to the earthy, herbal characteristics in the cup.
brewing methods that produce a heavier body, such as french press, moka pot, or espresso, suit this coffee well. a slightly coarser grind in immersion methods helps keep the earthy and herbal qualities balanced rather than sharp.
