Cold brew is the cheapest coffee shop drink to replicate at home: a $5 cafe pour costs roughly $0.40 to make in your kitchen, and the brewing itself is forgivingly low-skill. The question is which of the five popular methods to use. The Specialty Coffee Association’s 2025 home-brewing report shows mason jar and immersion brewers (OXO, Toddy) dominating US households, but each method produces a measurably different cup. After running the same coffee — Counter Culture Hologram, medium roast, coarse grind — through five methods over 30 days, here is the comparison.
At a Glance
| Method | Best For | Cost (Equipment) | Brew Time |
|---|---|---|---|
| Mason Jar + Cheesecloth | Bare-minimum starters | $5 | 18 hours |
| French Press | Already own one | $30 | 14 hours |
| OXO Brew Cold Brew Maker | Daily users | $50 | 12–24 hours |
| Toddy Cold Brew System | Serving 2+ daily | $40 | 12–24 hours |
| Hario Mizudashi Pot | Quick small batches | $25 | 8 hours |
The One Ratio You Need to Memorize
Before equipment talk, the most common cold brew mistake is wrong ratio. Use 1:8 coffee to water by weight for concentrate (dilute 1:1 with water or milk to drink) or 1:15 for ready-to-drink.
| Final Drink | Ratio | Example |
|---|---|---|
| Concentrate | 1:8 | 100g coffee : 800g water |
| Ready-to-drink | 1:15 | 100g coffee : 1500g water |
Coarse grind is non-negotiable. Fine grind extracts bitter compounds and clogs filters.
Method 1 — Mason Jar + Cheesecloth (Bare Minimum)
The cheapest possible setup. A 32-oz mason jar, a square of cheesecloth, and a fine-mesh strainer cover everything you need.
How:
- Add 80g coarse-ground coffee to a 32-oz mason jar
- Pour 640g cool filtered water, stir gently
- Cap and refrigerate 18 hours
- Strain through cheesecloth-lined fine mesh into a clean jar
Pros: Lowest equipment cost. Cleanup is the easiest of all methods.
Cons: Cheesecloth can leak fines into the brew. Multiple strain passes recommended.
Method 2 — French Press (If You Already Own One)
If a French press is already in your kitchen, skip buying anything new. The plunger acts as both brewer and filter.
How:
- Add 100g coarse-ground coffee to a 1L French press
- Pour 800g cool filtered water, stir
- Cap with plunger pulled up (don’t press), refrigerate 14 hours
- Press slowly and decant immediately into a clean container
Pros: Uses existing equipment. Fast cleanup compared to Toddy.
Cons: Press meshes can let fines through, producing slight sediment in the cup. Not ideal for serving guests.
Method 3 — OXO Brew Cold Brew Maker (The Daily Driver)
The OXO Brew is the most popular dedicated cold brew device for a reason: the Rainmaker shower head saturates grounds evenly, and the integrated paper filter removes nearly all sediment. Cleanup is the easiest of any dedicated brewer.
Pros: Cleanest cup of any method tested. Brews ready-to-drink concentrate up to 32 oz per batch. Replacement filters cheap ($6 for 10).
Cons: $50 entry price. Footprint is large for small kitchens. Glass carafe is fragile.
Method 4 — Toddy Cold Brew System (Best for High Volume)
The Toddy is the original cold brew system (patented 1964) and remains the best choice for households making cold brew daily for two or more people. The 12-cup capacity means one weekly brew session covers a couple’s full week.
Pros: 12-cup capacity (largest of any method tested). Reusable felt filter (replace every 6–12 months). Simple two-piece design.
Cons: Felt filter requires careful rinsing — develop a routine. Plastic feel of the brewing chamber.
Method 5 — Hario Mizudashi Pot (Best for Small Batches)
The Hario Mizudashi is a Japanese-designed glass pitcher with a built-in mesh insert. It brews 600 ml at a time and lives directly in the fridge door.
Pros: Brews in 8 hours (faster than other methods due to fine-mesh contact). Glass aesthetic is best of any tested. Smallest fridge footprint.
Cons: Smaller batch size means more frequent brewing for daily users. Mesh insert can be fiddly to clean.
Flavor Test Notes
Identical bean (Counter Culture Hologram), identical 1:8 ratio, brewed simultaneously over 24 hours. Three blind tasters scored on body, sweetness, clarity:
| Method | Body | Sweetness | Clarity |
|---|---|---|---|
| OXO Brew | 7 | 8 | 9 |
| Toddy | 8 | 8 | 8 |
| Hario Mizudashi | 7 | 8 | 8 |
| French Press | 8 | 7 | 6 |
| Mason Jar | 7 | 7 | 5 |
Differences are real but not dramatic. The bigger flavor variable is bean freshness (within 30 days of roast date) and brew time tuning.
Storage and Shelf Life
Cold brew concentrate keeps 7–10 days refrigerated; ready-to-drink keeps 5–7 days before flavor degrades. Store in airtight glass containers — plastic absorbs coffee oils over time.
Cost Per Pitcher
Assuming $14 for a 12-oz bag of specialty roast (yields ~3 pitchers):
| Method | Cost / 32 oz Pitcher |
|---|---|
| All methods (same beans) | ~$4.66 |
| Same volume from cafe | $20–25 |
Yearly savings versus a $5 daily cafe cold brew: roughly $1,500–$1,800.
Bottom Line
For most home brewers in 2026 the right pick is the OXO Brew Cold Brew Maker — cleanest cup, easiest cleanup, $50 pays back inside 30 cafe visits. The Toddy is the upgrade for households making cold brew daily for two or more. The mason jar method is the legitimate $5 starter to test if cold brew is part of your routine before buying anything.
