Cold Brew, Solved
Ratios, troubleshooting, and a foolproof workflow.
Cold brew doesn't have to be confusing. Whether you're grinding beans at home or using our seasonal cold brew pods, this guide walks you through foolproof ratios, steeping times, and quick fixes for every flavor issue. From sour to bitter to muddy, you'll know exactly how to adjust — and end up with smooth, café-quality cold brew every time.
US-first instructions with metric in parentheses, plus an optional shortcut using our seasonal cold brew pods. Beginner-friendly. No special gear required.

TL;DR
- Regular method (beans/ground): Make concentrate at 1:4 coffee:water. That's 7 oz coffee (200 g) to 27 fl oz water (800 mL), coarse grind, 12–18 hr in the fridge; cut 1:2–3 with water/milk to serve.
- Pods (50 g ≈ 1.8 oz, seasonal): Ready-to-drink: 1 pod : 16–17 fl oz water (475–500 mL). Concentrate: 2 pods : 13½ fl oz water (400 mL), then cut 1:2–3 in the cup.
- Fixes: Sour → slightly finer grind or longer steep. Bitter/muddy → coarser grind or shorter steep + paper filter polish.
Pods are a seasonal convenience. The regular method works year-round with any of our coffees.
Why Cold Brew Is Different
Hot coffee and cold brew aren't the same process slowed down — they're genuinely different extractions. Cold water pulls flavor out of coffee grounds far less efficiently than hot water does, roughly 60–70% as efficient at the same contact time. That gap is why cold brew ratios look nothing like drip ratios, and why the steep time is measured in hours instead of minutes.
It's also why roast selection isn't as simple as "light and medium are better for cold brew" — a claim you'll see repeated a lot. The truth is more useful than that: roast choice depends on what you want the finished drink to taste like, not on some roasts being objectively superior for the method.
Want low-acid and smooth? Reach for a darker roast, made into concentrate and cut with milk.
Want bright and juicy? A light or medium single origin, brewed closer to ready-to-drink strength, lets that character come through.
Want chocolatey and sweet? Medium to medium-dark roasts, especially dessert-leaning flavors, hold up beautifully cold.
There's no wrong answer here — just a mismatch between roast and goal if you don't think about it first.
2-Minute "Do This Now" Recipe (Concentrate, ~1 Qt)
Measure 7 oz coarsely ground coffee (200 g; texture = breadcrumbs).
Add 27 fl oz cold, filtered water (800 mL) to a large jar or brewer.
Optional bloom: pour ⅓ cup hot water (~3 fl oz / 100 mL) over grounds for 30 sec, then add the rest of the cold water.
Stir, cover, and refrigerate 14–16 hr.
Strain (fine mesh; for extra clarity, pass once through a rinsed paper filter).
Serve concentrate 1:2–3 with water or milk (e.g., ⅓ cup concentrate + ⅔–1 cup water/milk over ice).
Store concentrate 7–10 days chilled (brightest days 1–4).

Quick Ratio & Yield Table
| Use | Coffee : Water | Example (US) | Steep (Fridge) | Yields |
|---|---|---|---|---|
| Concentrate (strong) | 1 : 4 | 7 oz coffee → 27 fl oz water (200 g → 800 mL) | 12–18 hr | ~24 fl oz after filtration |
| Ready-to-Drink (direct brew) | 1 : 8–10 | 3.5 oz coffee → 28–35 fl oz water (100 g → 0.9–1.0 L) | 12–18 hr | ~27–30 fl oz |
| Cutting Concentrate | 1 : 2–3 (conc : water/milk) | 1 cup conc → 2–3 cups cut | — | café-strength iced coffee |
No scale? Cheats: 1 cup whole beans ≈ 3 oz (85 g); 1 heaping Tbsp ground ≈ ¼ oz (7–8 g). For ~1 qt concentrate use 3¼–3½ cups water and ~28 heaping Tbsp ground coffee.
Decision Tree: Fix It Fast
Sour / Lemony
- Grind one notch finer or steep +2–4 hr.
- Check dose; move toward 1:4 if under-dosed.
Bitter / Harsh
- Grind coarser or shorten to ~12 hr.
- Cut stronger concentrate more (try 1:3).
Muddy / Flat
- Polish once through a paper/cloth filter.
- Let concentrate rest 12–24 hr, then decant.
Too Weak / Too Strong
- Weak: cut less (1:2) or dose +10% next batch.
- Strong: cut more (1:3–4) or brew at 1:5 next time.
Workflows that Save You Time
- Batch once, sip all week: Brew 1.5–2 qt concentrate (e.g., 14 oz coffee → 54 fl oz water / 400 g → 1.6 L). Label date/ratio. Morning: ⅓ cup conc + ⅔–1 cup water/milk over ice.
- Zero-dilution iced latte: Freeze coffee ice cubes from concentrate; pour conc + milk over cubes.
- Creamy without gear: Want cold, frothy milk on top without a frother? Our Cold Foam guide covers every no-equipment method, mason jar included.

| Goal | Pods | Coffee | Water In | Brew | Notes |
|---|---|---|---|---|---|
| Small bottle RTD | 1 | 1.8 oz | 16–17 fl oz | RTD | 1–2 iced servings |
| Mason jar RTD | 2 | 3.5 oz | 32–34 fl oz | RTD | Smooth daily strength |
| Pitcher RTD | 4 | 7 oz | 64–68 fl oz | RTD | Parties & weekly prep |
| Compact concentrate | 2 | 3.5 oz | 13½ fl oz | Conc (1:4) | Cut 1:2–3 |
| Larger concentrate | 3 | 5.3 oz | 20 fl oz | Conc (~1:4) | Cut 1:2–3 |
| Family concentrate | 4 | 7 oz | 27 fl oz | Conc (1:4) | Cut 1:2–3 |
Pods in the decision tree: Sour → steep +2–4 hr or use 16 fl oz per pod. Muddy → don't squeeze; filter once through paper. Weak → use the 16 fl oz end or add a pod to a larger container. Strong → cut in cup like concentrate.
Storage & Freshness
- Grind fresh for cleaner flavor. If pre-ground, freeze in weekly portions; thaw sealed.
- Concentrate stays tasty 7–10 days (brightest days 1–4).
- Keep away from pungent foods — coffee absorbs aromas.
Health & Caffeine Notes
Cold brew often feels gentler than hot drip. Caffeine depends on dose/ratio; a 10–12 oz serving cut from concentrate is similar to a strong drip coffee. If sensitive, enjoy earlier in the day and cut more toward 1:3–4.
FAQ
Do I need a scale?
No. Use the No-Scale cheats above. A scale is most consistent, but cups/Tbsp get you close.
Fridge or countertop?
Fridge — cleaner flavor and food safety.
How long to steep?
Start 14–16 hr in the fridge; adjust within 12–18 hr based on taste.
How long does concentrate keep?
7–10 days chilled; best in the first 4 days.
Can I cold-brew flavored coffee?
Yes. For bigger aroma, brew concentrate (1:4) and cut to taste.
