How we assess these products
Our picks are research-led. We compare like-for-like on quality, value, ease of use and suitability for the job, drawing on manufacturer specifications and patterns across large numbers of verified customer reviews rather than cherry-picked quotes. We may earn a commission if you buy through our links, but this never affects how we rank or what we recommend. Read our full editorial standards.
1. Toddy Cold Brew System
The Toddy Cold Brew System has been the professional's choice since the 1960s, and it remains the most versatile and forgiving brewer on this list. Its patented two-stage design—brewing container with stopper, separate glass decanter—means you can steep a full litre of coffee or tea, then store the concentrate for up to three weeks without oxidation. The reusable felt filters catch even fine sediment, delivering clean, low-acid coffee (67% less acid than hot brew) and exceptionally smooth cold brew tea. It's equally happy with a robust roasted oolong or a delicate mizudashi sencha. The handle on the brewing container is a small mercy when manhandling a kilo of wet grounds, and the glass decanter with lid fits neatly in the fridge door. No electricity, no fuss, maximum flexibility.
- Genuine dual-purpose design; excels at both coffee and tea
- Concentrate stays fresh for three weeks—perfect for batch brewing
- Reusable felt filters deliver exceptionally clean brew
- Large capacity and robust glass decanter
- Filters require periodic replacement
- Takes up more counter/fridge space than bottle designs
2. HARIO Cold Brew Tea Bottle with Filter Insert, 750 ml FIB-75-SPR, Smoky Pink
Hario's 750 ml cold brew tea bottle is purpose-built for tea, and it shows. The integrated polypropylene filter basket sits snugly in the neck, allowing whole leaves to unfurl without escaping into the brew, and the heat-resistant glass body (with silicone rubber spout and stopper) is dishwasher-friendly. We found it particularly good with temperature-sensitive greens—the narrow filter keeps leaves contained, and the smoky-pink silicone adds a splash of colour to the fridge shelf. It handles coffee too, though the smaller capacity and narrower filter mean you'll be brewing in smaller batches. The spout pours cleanly, and the whole assembly disassembles in seconds for washing. If tea is your priority and coffee an occasional side quest, this is the one.
- Purpose-designed for tea with excellent leaf containment
- Heat-resistant glass and dishwasher-safe construction
- Compact 750 ml size fits easily in fridge door
- Clean-pouring silicone spout
- Smaller capacity limits batch brewing
- Polypropylene filter less effective with fine coffee grounds
3. Hario Cold Brew Coffee Wine Bottle, 700ml, Pale Grey
From Hario's Outdoor Line, this 700 ml wine-bottle-style brewer in pale grey is the most packable option here—lightweight, narrow, and designed to slot into a rucksack or picnic basket without complaint. The signature heat-resistant glass bottle is cadmium- and lead-free, dishwasher-safe, and pairs with Hario's separate filter inserts (not included in all listings, so check before buying). It's ideal for road trips, camping, or taking to the office. We found it slightly fiddly to clean by hand (small parts only), and the narrower profile means slower extraction with coarse coffee, but for cold brew on the move—especially chilled tea—it's hard to beat.
- Lightweight and portable; fits in bags and cup holders
- Heatproof glass, cadmium and lead free
- Dishwasher-safe bottle
- Stylish wine-bottle aesthetic
- Small parts must be hand-washed
- Narrow profile can slow extraction with coarse coffee
- Filter insert not always included—check listing
4. Cold Brew Coffee Filter for Wide Mouth Mason Jar, Food Grade 304 Stainless Steel, Ultra Fine Mesh, Tea and Fruit infuser, Iced Coffee Maker, Iced Tea Maker, Cold Brew Coffee Maker
If you already own a wide-mouth Mason jar (32 oz / ~950 ml or larger), this food-grade 304 stainless steel filter from iAesthete turns it into a functional cold brewer for under a tenner. The ultra-fine mesh copes with coffee grounds, whole-leaf tea, and even fruit infusions, and it's dishwasher-safe with no toxic BPA or bleach concerns. Setup is dead simple: drop the filter in, add grounds or leaves and water, refrigerate for 24 hours (coffee) or 6–8 hours (tea), and pour. The downside? You're dependent on the seal and shape of your jar, and the mesh can clog with very fine particles—expect a bit more sediment in the cup than with felt or paper filters. Still, for dorm rooms, hot-desking, or anyone on a tight budget, it's a perfectly serviceable entry point into dual-purpose cold brewing.
- Excellent value if you already have Mason jars
- Multi-functional: coffee, tea, fruit infusions
- Food-grade stainless steel, BPA-free
- Dishwasher-safe and easy to clean
- Requires separate wide-mouth Mason jar
- Ultra-fine mesh can clog with fine grounds
- More sediment in brew than felt filters
