Using Bodum Coffee Makers for Cold Brew

Quick answer

• Bodum coffee makers can be adapted for cold brew, though not all are designed for it.
• The key is a slow, long steep time with cold water and coarse grounds.
• Look for brewers with a fine mesh filter or a separate filter system.
• Proper ratios and grind size are crucial for a smooth, less bitter cold brew.
• Patience is essential; cold brew takes 12-24 hours to steep.
• Always check your specific Bodum model’s manual for brewing recommendations.

Who this is for

• Home coffee enthusiasts looking to experiment with cold brew.
• Owners of Bodum French presses or pour-over brewers who want to adapt them.
• Those seeking a less acidic coffee concentrate.

What to check first

Brewer type and filter type

Your Bodum brewer’s design will heavily influence how well it works for cold brew. French presses, with their built-in mesh filters, are often the most straightforward to adapt. Pour-over brewers might require a different filter than you typically use for hot coffee, or you might need to employ a secondary filtering method.

Water quality and temperature

For the best flavor, use filtered water. Tap water can introduce off-flavors that are more noticeable in cold brew due to the lack of heat to mask them. Always use cold or room temperature water; never hot water for cold brewing.

Grind size and coffee freshness

This is paramount for cold brew. You’ll want a very coarse grind, similar to breadcrumbs or coarse sea salt. Too fine a grind will result in over-extraction, bitterness, and sediment. Freshly ground beans are always best, but even with cold brew, avoid pre-ground coffee that’s been sitting for weeks.

Coffee-to-water ratio

A common starting point for cold brew concentrate is a 1:4 ratio of coffee to water by weight. For example, 4 oz of coffee to 16 oz of water. This can be adjusted to your preference for strength. Remember, this is a concentrate that you’ll likely dilute later.

Cleanliness/descale status

Ensure your Bodum brewer is thoroughly clean. Any residual coffee oils from previous brews can turn rancid and impart a stale flavor to your cold brew. If you haven’t descaled your brewer recently (for models that require it), do so before starting.

Step-by-step (brew workflow)

1. Gather your equipment: You’ll need your Bodum brewer, fresh coffee beans, a grinder, filtered water, a scale, and a timer.

• What “good” looks like: All necessary items are clean and ready to go.
• Common mistake: Not having everything ready, leading to rushed steps or forgotten ingredients.
• How to avoid: Set up your brewing station before you begin.

2. Measure your coffee beans: Weigh your whole coffee beans according to your desired ratio. A good starting point is 1:4 coffee to water by weight for a concentrate. For example, 4 oz of beans.

• What “good” looks like: Precisely measured beans, ready for grinding.
• Common mistake: Eyeballing the amount, leading to inconsistent results.
• How to avoid: Use a kitchen scale for accuracy.

3. Grind the coffee: Grind the beans to a very coarse consistency, like coarse sea salt or breadcrumbs.

• What “good” looks like: Uniform, large particles of coffee grounds.
• Common mistake: Grinding too fine, which will result in a muddy, bitter brew.
• How to avoid: Use a burr grinder set to its coarsest setting.

4. Add grounds to the brewer: Place the coarsely ground coffee into the bottom of your Bodum brewer. If using a French press, this is the carafe.

• What “good” looks like: A bed of coffee grounds at the bottom of the vessel.
• Common mistake: Not getting all the grounds into the brewer, affecting the ratio.
• How to avoid: Gently tap the grinder or container to ensure all grounds are transferred.

5. Add cold water: Slowly pour cold, filtered water over the grounds, ensuring all grounds are saturated. Start with about half of your total water volume.

• What “good” looks like: All coffee grounds are wet and beginning to bloom (expand slightly).
• Common mistake: Pouring water too quickly, which can create dry pockets.
• How to avoid: Pour water in a circular motion, starting from the center.

6. Bloom the coffee (optional but recommended): Let the grounds sit for 30 seconds to 1 minute. This allows trapped gases to escape.

• What “good” looks like: The coffee grounds swell and release small bubbles.
• Common mistake: Skipping this step, which can lead to a less efficient extraction.
• How to avoid: Be patient and allow the initial pour to sit briefly.

7. Add remaining water and stir: Pour in the rest of your cold, filtered water. Gently stir the mixture to ensure all grounds are fully submerged.

• What “good” looks like: A saturated slurry of coffee and water.
• Common mistake: Over-stirring, which can break down grounds and cause bitterness.
• How to avoid: Stir just enough to combine; a few gentle turns are sufficient.

8. Place the lid/filter assembly: If using a French press, place the lid on top without pressing the plunger down. For other brewers, follow your model’s instructions for covering.

• What “good” looks like: The brewer is covered to prevent evaporation and contamination.
• Common mistake: Leaving the brewer uncovered, allowing dust or other particles in.
• How to avoid: Always cover your brewing vessel.

9. Steep at room temperature or in the refrigerator: Let the coffee steep for 12 to 24 hours. Longer steeping generally results in a stronger, more concentrated brew.

• What “good” looks like: The coffee is steeping undisturbed.
• Common mistake: Not steeping long enough, resulting in a weak, underdeveloped flavor.
• How to avoid: Set a timer and let it steep for the full duration.

10. Plunge (for French press) or filter: If using a Bodum French press, slowly and gently press the plunger down to separate the grounds from the liquid. For other methods, carefully strain the liquid through your filter. You may need to double-filter if sediment is an issue.

• What “good” looks like: A clear or mostly clear liquid with minimal sediment.
• Common mistake: Plunging too quickly, forcing fine particles through the filter.
• How to avoid: Press the plunger down slowly and steadily.

11. Dilute and serve: Pour your cold brew concentrate over ice. Dilute with cold water or milk to your desired strength. A common starting point is 1:1 concentrate to water.

• What “good” looks like: A refreshing drink at your preferred strength.
• Common mistake: Drinking the concentrate straight, which is too intense.
• How to avoid: Always dilute to taste.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using too fine a coffee grind	Over-extraction, bitterness, sediment, clogged filter	Use a coarse grind, similar to sea salt or breadcrumbs.
Not steeping long enough	Weak, watery coffee with underdeveloped flavor	Steep for at least 12 hours, up to 24 hours, depending on desired strength.
Using hot water	Extracts bitter compounds, negates the purpose of cold brewing	Always use cold or room temperature filtered water.
Incorrect coffee-to-water ratio	Too weak or too strong concentrate	Start with a 1:4 ratio (coffee to water by weight) and adjust to your preference.
Skipping the bloom	Less efficient extraction, potentially more gas in the final brew	Allow grounds to sit for 30-60 seconds after the initial water pour.
Over-stirring	Can break down grounds, leading to bitterness and more sediment	Stir gently just enough to saturate all grounds.
Not cleaning the brewer thoroughly	Stale, rancid flavors contaminating the cold brew	Wash and rinse all parts of the brewer thoroughly after each use.
Plunging the French press too fast	Forces fine particles through the filter, resulting in sediment	Plunge slowly and steadily to allow the filter to work effectively.
Not diluting the concentrate	Extremely strong, bitter, and overwhelming flavor	Always dilute cold brew concentrate with water or milk to taste.
Using poor quality water	Off-flavors that are more noticeable in cold brew	Use filtered water for a cleaner, more pure coffee taste.
Not covering the brewer during steeping	Contamination from dust or other airborne particles, flavor degradation	Keep the brewer covered with its lid or a cloth during the steeping process.

Decision rules (simple if/then)

• If your Bodum brewer is a French press, then you can likely adapt it for cold brew because its mesh filter is suitable for coarse grounds.
• If you notice significant sediment in your cold brew, then your grind is likely too fine because finer particles pass through the filter more easily.
• If your cold brew tastes weak and watery, then you need to increase your coffee-to-water ratio or steep for longer because insufficient coffee or extraction time leads to dilution.
• If your cold brew is excessively bitter, then your grind might be too fine, or you steeped for too long because over-extraction extracts bitter compounds.
• If you’re using a Bodum pour-over brewer, then you may need an additional paper filter or a fine-mesh strainer to achieve a clean cup because the standard filter might let too many fines through for cold brew.
• If you want a smoother, less acidic coffee, then cold brewing is a good choice because the cold water extracts fewer acidic compounds than hot water.
• If you’re short on time, then cold brew is not the best option because it requires a long steeping period of 12-24 hours.
• If your cold brew has an off-flavor, then check your water quality or the cleanliness of your brewer because these are common culprits for undesirable tastes.
• If you prefer a lighter, more nuanced cold brew, then consider a shorter steeping time (12-16 hours) because longer times can sometimes mute delicate flavors.
• If you want a strong, rich cold brew concentrate, then use a higher coffee-to-water ratio (e.g., 1:3) and a longer steep time (18-24 hours) because this maximizes extraction.
• If you find your cold brew is too acidic even after brewing, then ensure you are using a very coarse grind and a long enough steep time because these factors contribute to a less acidic profile.

FAQ

Can I use any Bodum coffee maker for cold brew?

While many Bodum coffee makers, especially French presses, can be adapted for cold brew, not all are ideal. The key is a brewer that can accommodate coarse grounds and allow for a long, slow steep. Always check your specific model’s capabilities.

How long should I steep cold brew in my Bodum?

The steeping time for cold brew in a Bodum brewer typically ranges from 12 to 24 hours. Shorter times (12-16 hours) yield a lighter concentrate, while longer times (18-24 hours) produce a stronger, more intense brew.

What kind of coffee grind is best for Bodum cold brew?

You need a very coarse grind, resembling coarse sea salt or breadcrumbs. A fine grind will lead to over-extraction, bitterness, and a muddy brew that’s difficult to filter.

What’s the best coffee-to-water ratio for Bodum cold brew?

A common starting point for cold brew concentrate is a 1:4 ratio of coffee to water by weight (e.g., 4 ounces of coffee to 16 ounces of water). You can adjust this ratio to achieve your desired strength.

Is it okay to use my Bodum French press for cold brew?

Yes, a Bodum French press is an excellent tool for making cold brew. Its mesh filter is well-suited for the coarse grounds required, and the carafe is perfect for the steeping process.

What if my cold brew is too bitter when using a Bodum?

Bitterness often stems from over-extraction. Ensure you’re using a very coarse grind, not steeping for too long, and using cold water. If using a French press, plunge slowly.

How do I store my Bodum cold brew concentrate?

Store your cold brew concentrate in an airtight container in the refrigerator. It can typically last for up to two weeks, though the flavor is best within the first week.

Can I use my Bodum pour-over for cold brew?

While possible, a standard Bodum pour-over might require an additional fine-mesh filter or paper filter to prevent sediment in your cold brew. The coarse grounds needed for cold brew can sometimes pass through standard filters.
