Cold Brew at Home: Smooth, Strong, and Stupidly Easy

Of all the coffee methods, cold brew is the one with the highest taste-to-effort ratio. You don’t need a scale dialed to the gram, you don’t need to nail a 30-second window, you don’t even need hot water. You just need patience.

Here’s how we make ours — at home and in the pre-canned Velocity Vanilla and Drifter De Leche bottles you’ll see at events.

What cold brew actually is

Cold brew is coffee steeped in cold water for a long time. That’s it.

The cold water extracts the soluble flavors from the bean without the bitter compounds and acids that hot water pulls. The result is a coffee that’s:

• Smooth — the harsh edges are gone.
• Low-acid — easier on the stomach.
• Strong — long steep = high concentration.
• Sweet — natural sweetness comes forward without bitterness covering it.

Important: cold brew is NOT iced coffee. Iced coffee is hot-brewed coffee poured over ice. Cold brew is brewed cold from the start. Two completely different drinks.

What you need

• Coarse-ground coffee. Coarser than French press. Should look like raw sugar.
• Filtered water. Cold or room temp.
• A vessel. A mason jar, a French press, a pitcher, an empty milk jug — whatever holds liquid and seals.
• A filter. Cheesecloth, a coffee filter, a fine-mesh strainer, or the press in your French press.

That’s it.

The ratio

1 part coffee to 5 parts water by weight.

For a single 32 oz batch:

• 150g coarse-ground coffee (about 1.5 cups)
• 750g cold filtered water (about 25 oz)

That makes about 24 oz of finished concentrate after the grounds soak up some of the water.

This is a concentrate. Don’t drink it straight unless you’ve made some questionable life choices. Dilute it.

The dilution

1:1 with water or milk. That’s the standard.

• 4 oz concentrate + 4 oz water = 8 oz iced coffee.
• 4 oz concentrate + 4 oz oat milk = 8 oz cold brew latte.

Stronger? Try 2:1. Weaker? 1:2. Adjust to taste.

The brew

1. Combine coffee + water in your vessel. Stir to make sure all the grounds are wet.
2. Cover and put it somewhere it won’t get bumped. Counter is fine. Fridge is fine. Either works.
3. Wait.
   • 12 hours at room temp — fastest, slightly more acidic.
   • 18–24 hours in the fridge — smoother, more sweetness, our preference.
   • Past 24 hours: extract gets muddy. Stop at 24.
4. Strain. Slowly. Pour through your filter into a clean container. Don’t squeeze the grounds — that pushes bitter compounds through.
5. Store in a sealed container in the fridge. Lasts 2 weeks, easy. Tastes best in the first week.

The Lap24 way (cans)

The cans we sell — Velocity Vanilla and Drifter De Leche — go a step further:

• Slow-steeped 24 hours at controlled temp.
• Filtered twice for clarity.
• Real flavor, not artificial syrups (Velocity is real vanilla; Drifter is dulce de leche).
• Oat milk base so they’re dairy-free.
• 100mg caffeine per can — a controlled dose, not a wildcard.

When we don’t have time to make a batch at home, we drink the cans. They’re dialed in better than what we can pull off in the kitchen on a busy week.

Tweaks worth trying

• Vanilla bean — split a vanilla bean and steep it with the coffee. Smooth, sweet, no syrup needed.
• Cinnamon stick — one stick per batch. Subtle, warming, fall-coded.
• Sea salt — a tiny pinch in the finished concentrate. Cuts bitterness, brightens sweetness. Sounds wrong, tastes right.
• Sweetened condensed milk — Vietnamese-style. 1 part SCM to 4 parts cold brew over ice. Game changer.

The brand we picked for cold brew

The cold brew you make at home or buy in a can is only as good as the bean it started from. We use medium-to-medium-dark roasts for cold brew because:

• The longer roast develops chocolate and caramel notes that come through cold.
• The lower acidity at darker roasts is amplified by the cold extraction.
• Bright single-origins disappear — their delicate notes get lost in cold water.

If you’re choosing a bag for cold brew, skip the bright Ethiopian. Reach for the chocolate-forward Brazil, Colombia, or a darker blend. The Daily Driver works great.

TL;DR

1. 150g coarse coffee + 750g cold water.
2. Steep 18–24 hours in the fridge.
3. Strain.
4. Dilute 1:1.
5. Drink cold. All summer.

Or just grab a 6-pack of cans and skip the wait.
