Costa Rican Cold Brew Guide

Cold brew made with Costa Rican honey process coffee is one of the best things you can make at home — no equipment beyond a jar and a filter, naturally sweet without added sugar, smooth and refreshing. Here's everything you need to know.

Why Costa Rican coffee and cold brew are a perfect match

Cold brew extracts coffee slowly in cold water over 12–18 hours. This slow extraction pulls out sugars and body while leaving behind most of the acids and bitter compounds that hot water extracts quickly. The result is a naturally smooth, low-acidity concentrate.

Costa Rican honey process coffee has a head start on sweetness — the mucilage left on the bean during processing imparts natural fruit sugars. Cold brew amplifies that sweetness further. The combination produces a cup that tastes almost dessert-like without any added sugar.

What you need

• A wide-mouth mason jar or any container with a lid (32oz / 1L works well)
• A fine mesh strainer or paper filter (a pour over dripper with a paper filter works great)
• Coffee: 80g coarsely ground Costa Rican honey process
• Cold or room temperature filtered water: 500ml

The recipe — concentrate method

This makes a 1:6 ratio concentrate. Dilute 1:1 before drinking.

1. Grind 80g of coffee coarsely — think rough sea salt or slightly coarser.
2. Add grounds to the jar. Pour 500ml of cold filtered water over them.
3. Stir gently to make sure all grounds are wet.
4. Cover and refrigerate for 14–18 hours. (12 hours minimum, 20 hours maximum.)
5. Strain through a fine mesh strainer lined with a paper filter, or through a pour over setup. This takes 5–10 minutes — don't rush it.
6. Transfer the concentrate to a clean jar. Keeps refrigerated for up to 2 weeks.

To serve: Fill a glass with ice, add equal parts concentrate and cold water (or milk). Adjust to taste. No sugar needed if you used honey process.

Which Costa Rican region is best for cold brew

• Honey process from any region: Best choice. The natural sweetness shines in cold brew.
• Valle Central medium roast: Great body and caramel notes that come through beautifully cold.
• Tarrazú light roast: Produces a more citrus-forward cold brew — interesting, but not as crowd-pleasing as honey process.
• Brunca: Bold and chocolatey cold brew. Excellent with milk.

Tips for the best results

• Coarse grind is essential. Fine grounds make the straining take forever and can make the cold brew bitter. Use your coarsest setting.
• Use fresh beans. Cold brew requires more coffee than hot methods — stale beans make it flat and papery.
• Don't rush the extraction. Under 12 hours and the cold brew will taste weak and sour. Over 20 hours it can get astringent.
• Strain completely. Sediment in the concentrate keeps extracting in the fridge. A paper filter gets the cleanest result.
• Taste before diluting. The concentrate is very strong on its own — taste it, then dilute to preference.

Variations worth trying

• Cold brew tonic: Mix cold brew concentrate with sparkling tonic water over ice. Add a slice of orange. The citrus notes of Costa Rican coffee work beautifully here.
• Milk cold brew: Use whole milk or oat milk instead of water for the dilution. Adds creaminess and amplifies the sweetness.
• Nitro-style: Pour cold brew into a whipped cream canister, charge with N2O, and dispense over ice. Smooth, creamy, cafe-quality at home.
