Where can I buy Sumatra coffee beans? How to brew and drink Sumatra coffee?

Buying Tips

Taobao is full of options, so watch the price and buy from established producers. Bags priced at a few tens of yuan are usually ordinary beans taken to a deep roast.

For dependable quality, expect to pay around 100 yuan for half a pound of roasted beans.

Be skeptical of so-called "hand-roasted" beans. Small-batch hand roasting should, in theory, cost more - yet on Taobao it is oddly cheap.

Avoid beans that look excessively oily; that is a sure sign of amateur roasting.

Tasting Results

1. Light Roast

Noticeable fruit acidity but comfortable on the palate, slightly bitter, with a mouth-watering sensation on both sides of the mouth and moderate smoothness.

2. Medium-Dark Roast

Beautifully balanced, rich and full-bodied, with pronounced bitterness. Chocolate and a subtle sweetness come forward, along with a distinct licorice aroma, better smoothness than the light roast, and a powerful aroma.

3. Dark Roast

Almost no acidity, very heavy bitterness, and, if the roast is even slightly off, burnt flavors.

Over-Extraction and Under-Extraction

Over-extraction

Shows up as coffee that is overly bitter and astringent, caused by water sitting in the grounds for too long.

Under-extraction

Gives a relatively thin body, with the feeling that the water and the coffee are separate.

Brewing Methods and Equipment

Different methods also bring out different flavors.

Pour-Over

1. Dripper: Hario V60
2. Water temperature: 88 degrees C
3. Grind: Fujiyama grinder setting 4
4. Roast level: Medium-dark
5. Bloom time: 25 seconds

Flavor: layered, clean, and balanced, with a persistent caramel sweetness in the finish.

Method: 15g of coffee ground on a Fujiyama ghost-tooth grinder at setting 4, a V60 dripper, and water at 88-89 degrees C. First pour 30g of water for a 25-second bloom, then pour to 104g and stop. When the water level drops to half, continue pouring slowly until you reach 220g, and discard the last 5g. Coffee-to-water ratio 1:15, total extraction time about 2:00.

AeroPress

1. Water temperature: 85 degrees C
2. Grind: Fujiyama grinder setting 3.5
3. Roast level: Medium-dark
4. Bloom: two stages - 20 seconds, then 50 seconds

Method: Set the AeroPress up for a standard press. Use 20g of coffee at a 1:17 ratio. First pour 100g of 83 degrees C water, stir 3-5 times to wet the grounds evenly, and let stand for 20 seconds. Add the rest of the water to reach 240g, let stand for 40 seconds, then stir for 5 seconds. At 1 minute 50 seconds, insert the plunger and press down. Total time: 2 minutes 5 seconds.

Flavor: rich and complex, with prominent spice and fresh forest aromas.

Siphon

1. Water temperature: 90 degrees C
2. Grind: Fujiyama grinder setting 3.5
3. Roast level: Medium-dark
4. Brew time: 30 seconds

Method: Side-heating extraction. Use 20g of coffee for 2 servings at a 1:12 ratio, with the water line at mark 2. Use the delayed-addition approach - add the coffee after the bubbles form. Stir 4-5 times, extract for about 30 seconds, then remove from the heat. Finally, stir twice and let the coffee fall naturally.

Flavor: smooth and rich, with prominent herbal and bitter notes and a distinct caramel sweetness.

Sumatra Coffee Bean Brands

FrontStreet Coffee's roasted Sumatra coffee, Golden Mandheling, is a safe bet on both brand and quality, and the value is outstanding: a 227g package costs just 89 yuan. At 15g per cup, that is 15 cups per bag, or about 6 yuan a cup. Compared with coffee shops that charge tens of yuan per cup, it is an easy recommendation.

FrontStreet Coffee Recommendation

For the fullest expression of wet-hulled Sumatra, FrontStreet's PWN Golden Mandheling is the top of the line. PWN buys only high-grade Mandheling green beans, then screens out defects by machine and by hand - beans at 18 mesh and above, with fewer than three defects per 300-gram sample, followed by three rounds of hand sorting. Roasted medium-dark, the beans are large, even, and glossy, with a clean, full-bodied cup of black chocolate, spice, and caramel - ideal for anyone who dislikes acidity.

If you want the everyday version of the same profile, FrontStreet's Lintong Mandheling is the answer. Grown around Lake Toba in North Sumatra and wet-hulled in the traditional way, it is medium-dark roasted for a bold, low-acid cup with black chocolate, caramel, cedar, and a wild herbal edge. Try it as a three-stage V60 pour - 15g of coffee, a 1:15 ratio, and water at 87-88 degrees C - to draw out both its body and its caramel sweetness.
