Mad House Roast Cold Brew Recipe (100g to 800g)

Spotted: a jar of coffee left alone on the counter overnight, doing absolutely nothing and getting better by the hour. Some of us could learn from that, darling.

Short answer: Combine 100g of coarsely ground coffee with 800g of cold, filtered water, cover, and steep at room temperature for 12 to 18 hours. Strain, then dilute with equal parts water or milk to taste and serve over ice.

• Coffee: 100g, coarsely ground. Any of our coffees works, and we recommend The Mad House Roast for chocolate warmth
• Water: 800g, filtered
• Temperature: Cold water, steeped at room temperature
• Grind: Coarse
• Brewer: A large jar or French press, plus cheesecloth or a fine-mesh strainer
• Total time: 12 to 18 hours

Steps

1. Combine the coffee and water in your jar or French press.
2. Stir once so that all of the grounds are wet.
3. Cover and let it rest at room temperature for 12 to 18 hours.
4. Filter through cheesecloth or a fine-mesh sieve. Filter twice if you want a clearer cup.
5. Dilute with equal parts water or milk, to taste. Serve over ice.
6. Keep the rest in the refrigerator for up to a week. This makes approximately 500g of concentrate.

Why this works

Cold brew trades heat for time. A long, patient steep with coarse grounds gives you a smooth concentrate that you dilute to the strength you like. The Mad House Roast is a natural Yellow Bourbon from Brazil with chocolate, caramel and nutty notes, and those are exactly the flavours that stay friendly when served cold, with or without milk.

If it tastes off

• Sour or thin: Steep closer to the 18 hour end of the range next time, or use a little less water or milk when you dilute.
• Bitter or dry: Steep closer to 12 hours next time, or add a little more water or milk to your glass.

Quick answers

Can I use room temperature water?

Yes, if you are feeling impatient. The recipe calls for cold, filtered water, but room temperature water works too.

How long does the concentrate keep?

Up to a week in the refrigerator. If it lasts that long.

Can I add anything to the jar?

For a festive touch, add a cinnamon stick or a piece of orange peel to the jar before steeping. Or do not. It is your cold brew.

For the chocolate-warm version, steep The Mad House Roast.
