Why brewing method matters for Sumatra Gayo
Sumatra Gayo is a dark roast from Indonesia's Aceh region, known for its rich, complex profile with low acidity. Its bold flavor can turn bitter if over-extracted, so precise brewing is key to balance the chocolate and fruit notes without harshness.
Because it's a dark roast, the beans are more porous and extract faster than lighter roasts. A slightly coarser grind and cooler water help you avoid astringency while still getting full body.
Step-by-step brewing guide
- Choose your grind size: For a pour-over or drip machine, use a medium-coarse grind (like sea salt). For a French press, go coarser (like breadcrumbs). For espresso, use a fine grind but pull a shorter shot to avoid bitterness. Too fine a grind can make the cup taste bitter and muddy. Adjust only one variable at a time.
- Measure your coffee and water: Use a 1:16 ratio — for every 1 gram of coffee, add 16 grams of water. A standard cup uses 15g coffee to 240g water. The 5LB bag gives you about 150 cups at this ratio. Weighing is more accurate than scooping. A kitchen scale costs little and improves consistency.
- Heat water to 195-200°F: If you don't have a variable-temperature kettle, bring water to a boil and let it sit for 30 seconds. Water that's too hot (near boiling) over-extracts dark roasts, making them taste ashy. Cooler water preserves the chocolate and stone fruit notes. Taste the difference side by side to find your sweet spot.
- Bloom and pour: For pour-over, wet the grounds with twice their weight in water and wait 30 seconds. Then pour in slow circles, keeping the water level just above the bed. Total brew time should be 3-4 minutes. Skipping the bloom can cause uneven extraction and a flat-tasting cup. Always use fresh, filtered water.
- Serve and store: Drink within 15 minutes for best flavor. Store the remaining 5LB in an airtight container away from light and heat. Divide into smaller portions to reduce air exposure each time you open it. Whole beans stay fresh longer than ground. Grind only what you need for each brew.
