Brewing cold brew coffee at home requires minimal equipment. Whether you prefer a simple mason jar or an advanced brewing device, you can make delicious cold brew with various methods. This guide covers all options available to beginners, from DIY solutions under $10 to specialized brewers costing over $100, helping you choose based on your budget, lifestyle, and coffee preferences.
Equipment Overview
Cold brew doesn't require fancy equipment. The basic principle remains constant: coarse coffee grounds + cold water + time = cold brew concentrate. However, different equipment options offer varying levels of convenience, filtration quality, and brew consistency.
What You'll Always Need
- Container - holds water and grounds
- Filtration method - separates grounds from liquid
- Measuring tools - scales or cups for consistency
- Stirring utensil - spoon or wooden stick
- Storage container - for finished concentrate
Everything else is optional and designed to improve convenience or consistency.

Filtration Methods Explained
Mesh Filters
Most commonly found in commercial immersion brewers. Mesh filters allow small particles through, resulting in a slightly thicker texture. They're reusable and environmentally friendly but require thorough cleaning. Works well for most home brewers.
Paper Filters
Used in Toddy makers and AeroPress. Paper creates the clearest final product by removing fine particles completely. This results in a cleaner taste but requires purchasing filters. Best for purists who prefer clarity.
Cloth Filters
Traditional cheesecloth or specially designed fabric filters. Reusable and affordable, but require careful handling and maintenance. Many home brewers repurpose kitchen towels for this purpose.
Multiple-Pass Filtering
Some advanced brewers use multiple filtration layers. Starting with coarse straining, then fine mesh, then paper. This creates the smoothest possible cold brew but takes more time and resources.
💡 Filtration Pro Tip
For the clearest cold brew at home, use a two-step filtration system: first strain through a coarse mesh or cheesecloth, then pour through a paper filter or fine metal strainer. This removes sediment while preserving flavor.
Additional Accessories
Coffee Grinders
Essential for fresh cold brew. Use a burr grinder (not blade) to achieve the coarse consistency cold brew requires. Budget options start at $20-30.
Digital Scales
Enables precise coffee-to-water ratios for consistency. Kitchen scales cost $15-40 and significantly improve brewing results.
Airtight Containers
For storing finished cold brew. Glass containers with proper seals maintain freshness for 2 weeks. Cost: $10-25.
Cheesecloth & Filters
Bulk cheesecloth ($5-10) lasts for months. Paper filters vary by brewer ($3-8 per 100 count).
Straining Utensils
Fine mesh strainers, small colanders, or dedicated coffee strainers. Budget: $8-20.
Equipment Recommendations by Situation
I'm on a tight budget (under $10)
Best choice: Mason jar with cheesecloth
You likely already have a mason jar at home. Pair it with cheesecloth from your local grocery store, and you have everything needed for excellent cold brew. While manual filtering takes longer, the quality is comparable to expensive equipment.
Setup:
- Mason jar (you probably own this): $0
- Cheesecloth: $3-5
- Measuring cup: $0 (use what you have)
- Total: $3-5
I want something simple but not DIY ($20-50)
Best choice: Commercial immersion brewer
Brands like Bodum or other mid-range brewers offer built-in filtration without the mess of manual filtering. These are designed specifically for cold brew and take up minimal space.
Why choose this:
- Purpose-built for cold brew
- Built-in filtration (no cheesecloth needed)
- Consistent results batch to batch
- Stores easily in the refrigerator
I care about environmental impact
Best choice: Japanese strainer or reusable mesh system
Avoid disposable filters by choosing equipment with permanent filtration. Japanese strainers and metal mesh filters eliminate ongoing waste.
Why choose this:
- No disposable filters ever needed
- Long lifespan (10+ years)
- Works with any container you have
- Beautiful to display or gift
I want the clearest, smoothest brew possible
Best choice: AeroPress with paper filters or double-filtered system
For the absolutely clearest cold brew, use paper filtration with multiple passes. AeroPress excels at this, or combine an immersion brewer with a secondary paper filter stage.
Why choose this:
- Paper filters remove all fine particles
- Produces crystal-clear concentrate
- Smooth, clean flavor profile
- Professional café-quality results
I brew cold brew daily and want it automated
Best choice: Premium cold brew system ($100+)
Automated brewers handle the entire process with minimal intervention. Some feature temperature control for faster brewing or slow dispensing for optimal extraction.
Why choose this:
- Minimal daily effort required
- Consistent, professional results
- Some models include temperature control
- Beautiful enough for countertop display
- Large capacity for frequent consumption
I travel or need portability
Best choice: AeroPress or travel-sized immersion brewer
Small, lightweight equipment that fits in luggage. AeroPress is especially popular with travelers since it's durable and requires minimal space.
Why choose this:
- Compact and lightweight
- Durable construction survives travel
- Works anywhere with water access
- Quick brewing process for instant gratification
Common Equipment Mistakes to Avoid
1. Using the Wrong Grind Size
Many beginners use medium or fine grind coffee. Cold brew requires coarse grounds—similar to French press. Fine grounds lead to over-extraction and bitterness.
2. Buying a Grinder Without Grinding Equipment
It's tempting to buy whole bean coffee, but without a proper burr grinder, you'll struggle. Invest in a grinder before premium beans. Blade grinders create inconsistent grind sizes.
3. Skipping Filtration Equipment
Attempting to use regular coffee filters with mason jars often fails. Invest in proper filtration—whether cheesecloth, mesh, or commercial filters—from the start.
4. Choosing Equipment Too Small
Single-serving brewers like small AeroPress get tedious if you drink cold brew daily. Get something with at least 1-quart capacity if you're a regular consumer.
5. Ignoring Storage Equipment
Finished cold brew concentrates will absorb refrigerator odors in ordinary containers. Use airtight, glass storage containers to maintain quality for the full 2-week shelf life.
Maintenance & Care
Daily Cleaning
- Rinse all equipment immediately after use
- Remove residual grounds with running water
- For mesh filters, use a soft brush to clean filter holes
- Allow everything to air dry completely
Weekly Deep Clean
- Soak equipment in equal parts white vinegar and water (30 minutes)
- Scrub with a small brush to remove mineral buildup
- Rinse thoroughly multiple times
- Air dry in a clean location
Storage Tips
- Store equipment in a cool, dry location
- Keep spare filters or cheesecloth in sealed bags
- Store finished concentrate in airtight glass containers
- Label containers with brew date (cold brew keeps 2 weeks)
