Learn how to brew cold-brew coffee at home using a natural process single-origin like AUTUMN COFFEE. This guide covers grind size, ratio, steeping time, and tips for a silky, low-acid cold brew.
Cold brew is one of the most forgiving and rewarding ways to enjoy specialty coffee at home. Its naturally sweet, low-acid profile highlights the fruit-forward notes that natural process coffees are known for. Whether you're new to cold brew or looking to refine your technique, this guide will walk you through every step using a high-quality natural process coffee from THE BARN Coffee Roasters.
We recommend starting with a coffee like AUTUMN COFFEE, a natural-process Ethiopian that brings intense berry and stone-fruit sweetness to the brew, or KABINGARA AB, a washed Kenyan that also shines in cold brew with its bright acidity and blackcurrant notes. Both are excellent choices for a refreshing cold-brew concentrate.

Why Natural Process Coffees Excel in Cold Brew
Natural (or dry) process coffees are dried inside the whole cherry, which allows sugars and fruit mucilage to absorb into the bean. This creates a flavor profile bursting with ripe fruit, floral aromatics, and wine-like complexity. When steeped cold, these vibrant flavors are extracted gently without the bitterness or astringency that can come from hot brewing. The result is a silky, sweet concentrate that tastes almost like fruit tea.
A coffee like AUTUMN COFFEE, with its notes of wild berries and chocolate, becomes incredibly smooth and approachable in cold brew. The natural process preserves the berry sweetness while the cold extraction tames any sharp edges. For a different profile, KABINGARA AB offers a cleaner, more acidic cup that still rounds out beautifully when steeped for 12–18 hours.
- Natural process coffees retain more fruit sugars, making them ideal for sweet, full-bodied cold brew.
- Cold extraction highlights the coffee's origin character without over-extracting bitter compounds.
The Perfect Cold Brew Recipe: Ratio, Grind, and Time
For a balanced cold brew concentrate, use a 1:8 coffee-to-water ratio by weight. For example, 100 grams of coarsely ground coffee to 800 grams (800 ml) of filtered water. This yields a concentrate you can dilute 1:1 with water or milk. If you prefer ready-to-drink strength, use 1:12.
Grind your coffee on the coarsest setting your grinder allows — think breadcrumb texture, not powder. A coarse grind ensures even extraction over many hours and prevents over-extraction and sludge. Steep at room temperature for 14–18 hours, then filter through a paper filter or a fine-mesh sieve lined with a cloth. The long steep time extracts deep sweetness and body while keeping acidity low.
- Ratio: 1:8 (coffee:water) for concentrate; 1:12 for ready-to-drink.
- Grind: coarse, like sea salt. Avoid fine grinds — they clog filters and cause bitterness.
- Time: 14–18 hours at room temperature. Refrigerate after filtering.
- Filtering: use a paper filter for the clearest cup; a fine-mesh strainer works too.
Step-by-Step Cold Brew Instructions
Start by measuring your coffee. Weigh 100 grams of whole-bean coffee, such as AUTUMN COFFEE or KABINGARA AB, and grind it coarsely. Place the grounds in a large jar or pitcher. Add 800 grams of filtered water, stirring gently to ensure all grounds are saturated. Cover and let it steep at room temperature for 14–18 hours.
After steeping, pour the mixture through a paper filter set in a mesh sieve over a large bowl or pitcher. Allow it to drip through naturally — don’t press or squeeze the grounds, as that can push bitter compounds into the brew. Once filtered, transfer the concentrate to a clean bottle and refrigerate. It keeps for up to two weeks. To serve, pour over ice and add water or milk to taste.
- Use filtered water for the cleanest flavor.
- Stir the grounds once halfway through steeping for more even extraction.
- Store concentrate in an airtight container in the fridge.
Tips for the Best Natural Process Cold Brew
One common mistake is using too fine a grind or steeping too long. With natural process coffees, the fruit sugars can over-extract and become cloying if you exceed 20 hours. Stick to 14–18 hours. Also, ensure your coffee is fresh — ideally within two weeks of roast date — to capture the full aromatic spectrum.
Experiment with different natural process coffees from THE BARN. AUTUMN COFFEE delivers a berry-forward sweetness that pairs beautifully with oat milk. For a more complex, wine-like cold brew, try KABINGARA AB. Each origin brings its own character to the cold brewing process, making it a fun journey to explore.
- Don’t exceed 18 hours of steeping for natural process coffees to avoid overly fermented notes.
- Dilute concentrate with still or sparkling water for a refreshing summer drink.
- Use a digital scale for consistent results.
