Toddy Cold Brew Systems

Choosing the Right Toddy System

Toddy's range divides clearly into home systems and commercial systems. The right choice depends on batch size and how frequently you brew.

Home Systems

Toddy Home Cold Brew Coffee Maker — The original Toddy system and still the benchmark for home cold brew. Brews up to 1.1 litres (approximately 11 cups) of concentrate per batch using a 12–24 hour cold steep. The system consists of a brewing container with a rubber stopper and felt filter, a glass decanter for storing the finished concentrate, and a lid. Simple to use: add coarsely ground coffee and cold water, leave to steep, drain into the decanter, refrigerate. The concentrate keeps for up to two weeks in the fridge. One of the most reliable and widely used cold brew systems available for home use.

Toddy Go Brewer — Portable Cold Brew Coffee Maker — A compact, portable version of the Toddy system designed for single-serving cold brew on the go. The Go Brewer steeps and serves in a single vessel — no separate decanter required. Brew a single serving at home or take it with you to steep overnight wherever you are. A practical option for solo cold brew drinkers who want the Toddy cold extraction quality in a travel-friendly format.

Commercial Systems

Toddy Commercial Cold Brew System — A larger-capacity commercial cold brew brewer designed for café and restaurant use. Brews a larger batch than the home system and is constructed for repeated daily use in a professional environment. Currently sold out — contact us for restock updates.

Toddy Café Series 10 Cold Brew System — 10 Litre — A 10-litre commercial cold brew brewer for high-volume café production. Designed for cafés that serve cold brew on tap or in bottles and need to brew large batches consistently. The Café Series 10's 10-litre capacity is sufficient for a full day's cold brew service at most independent café volumes. Includes a spigot for clean dispensing direct from the brewing vessel without pouring.

Toddy Pro Series Cold Brew System — Toddy's top-tier commercial system, designed for continuous high-volume cold brew production. Available in multiple configurations to suit different production requirements. The Pro Series is the system of choice for cold brew operations that produce at scale — bottlers, roasteries, and high-volume cafés with dedicated cold brew programmes. The matching Pro Series filters are available separately and are sized specifically for the Pro Series brewing vessel.

Filters & Accessories

All Toddy systems use a filter to strain the concentrate as it drains from the brewing vessel. Different filter types suit different systems and preferences — the right filter makes a significant difference to clarity, workflow and long-term running cost.

• Toddy Felt Filter Packs — Home Cold Brew System — Reusable felt filters for the Toddy home system. Each felt filter can be rinsed and reused multiple times before needing replacement. The felt material produces a clean, sediment-free concentrate without completely stripping the coffee's body — a balanced filtration option for the home system.
• Toddy Cold Brew Paper Filter Bags — Single-use paper filter bags for the Toddy home system. Paper filters produce a cleaner, brighter concentrate than felt, removing more fine particles for a lighter-bodied result. Preferred by brewers who like a particularly clean cold brew — closer in character to filtered hot coffee than the heavier body produced by felt filtration. Each bag is used once and disposed of.
• Toddy Commercial Model Paper Filters — 50 Pack — Single-use paper filters for the Toddy commercial system. A 50-pack provides extended supply for daily commercial use.
• Toddy Commercial Model Tree-Free Filters — An alternative to paper filters for the commercial system, manufactured without wood pulp — a more sustainable filter option for commercial operations with environmental commitments. Currently sold out.
• Toddy Cold Brew Cupping Kit — Tree Free Filters — A cupping and evaluation kit with tree-free filters, suited to coffee professionals who want to evaluate cold brew extraction quality using standardised tasting protocols.
• Toddy Café Series 10 Paper Filters — Dedicated paper filters for the Café Series 10 system, sized for the 10-litre brewing vessel.
• Toddy Pro Series Cold Brew Filters — Replacement filters for the Pro Series system, available in multiple pack sizes.
• Toddy Commercial Cold Brew Spigot — A replacement or additional spigot for the commercial Toddy system, allowing clean tap-style dispensing from the brewing vessel.
• Toddy Commercial Model Brew Paddle — A stirring paddle for the commercial system, used to ensure even saturation of coffee grounds during the initial charge of water.
• Toddy Replacement Brewing Container with Handle — A replacement brewing container for the home system. Currently sold out.

Frequently Asked Questions

How does cold brew differ from iced coffee?

Iced coffee is hot-brewed coffee that is then chilled or poured over ice — it retains the acidity of hot extraction and tends to taste more bitter and dilute as the ice melts. Cold brew is extracted using cold water from the start, over a long steep time of 12–24 hours. The cold-water extraction process draws different compounds from the coffee than hot water does — specifically, it extracts significantly less of the acids and bitter compounds that hot water releases quickly. The result is a concentrate that is naturally smoother, sweeter and lower in acidity than any chilled hot coffee, with a flavour profile that holds up well over ice and dilution without tasting flat or bitter.

How long does cold brew concentrate keep?

Cold brew concentrate made with the Toddy home system keeps for up to two weeks refrigerated in the glass decanter. This is one of cold brew's most practical advantages — a single batch brewed on a Sunday lasts the whole working week and beyond, ready to pour over ice or mix with water or milk in seconds. Once diluted, cold brew should be consumed within a day or two. Commercial batches follow the same general principle, though production volumes and turnover in a café environment typically mean batches are consumed well within that window.

What grind size should I use for cold brew?

Coarse — similar to the grind used for a French press, or slightly coarser. A coarse grind slows extraction during the long steep, preventing over-extraction and the bitterness that comes with it. A medium or fine grind will over-extract during a 12–24 hour steep, producing a harsh, bitter concentrate rather than the smooth result cold brew is known for. If you're using a burr grinder, set it to your French press setting and grind fresh for each batch. The Toddy home system is particularly forgiving of minor grind variation given the long steep time, but a consistent coarse grind reliably produces the best results.

How much water and coffee do I use for the Toddy home system?

The standard Toddy home recipe uses 340g (12oz) of coarsely ground coffee and 1.7 litres (56oz / 7 cups) of cold water. This produces approximately 1.1 litres of concentrate after straining — enough for 11 cups when diluted 1:1 with water, or up to 22 if you prefer a lighter ratio. Toddy also recommends a two-stage water addition — add half the water first, wait a few minutes for the grounds to fully saturate, then add the remaining water — to ensure even wetting of the coffee bed. Total steep time is 12–24 hours in the fridge; 12–16 hours tends to produce a brighter, lighter result, while 20–24 hours produces a heavier, more concentrated cup.

Can I make tea or other drinks with the Toddy system?

Yes — the Toddy cold extraction method works equally well for tea, producing a very smooth, clean cold brew tea concentrate with none of the bitterness that hot-steeped tea can develop. The same principle applies: use a coarser leaf or larger tea bags, steep in cold water for 6–12 hours (tea extracts faster than coffee in cold water), and dilute to taste. The system is also used by some cafés for cold brew herbal infusions, spice-infused waters and other speciality drinks. The Toddy is fundamentally a cold-water extraction vessel, and anything that benefits from slow, cold steeping works well in it.
