This is the recipe Toddy publishes for this brewer, and it is what Cold Brew Studio opens with when you pick it. It makes about 7¾ cups, best cut with a little water or milk.

How the maker does it

Toddy's current (2022) official brewing guide gives two methods for the same brewing container, both using 12 oz (340g) of coarsely ground coffee and 8 cups (64 fl oz / 1.9L) of filtered water. Method 2 ('Classic', the original 1964 method, reusable felt filter only): dampen the felt filter, add 1 cup water + 6 oz grounds, slowly pour 3 more cups over the grounds in a circular motion, wait 5 minutes, add the remaining 6 oz grounds, then slowly add the last 4 cups of water. DO NOT STIR — stirring the bed of grounds can clog the felt filter; instead lightly press down on the topmost grounds with the back of a spoon to ensure saturation. Steep at room temperature 8-24 hours ('to create a smooth, rich flavor'). Remove the stopper to let concentrate flow into the glass decanter (keeps up to 2 weeks refrigerated). Serve starting at a ratio of 1 part coffee concentrate to 2 parts water or milk, mixed to taste. (Toddy's older 2010 manual specified 7 cups/56 fl oz water, a fixed 12-hour steep, and a 1:3 serving dilution — the numbers here reflect the current official guide.) Method 1 ('Dual Filtration', paper filter bag + felt) uses identical 12oz coffee / 8 cup water amounts but is recommended for easier cleanup and tolerates a wider range of grind sizes.

The recipe, by strength

Each one fills this brewer as far as it honestly goes. Numbers are for a light roast steeping in the fridge.

Strength	Ratio	Coffee	Water	Steep	Makes	Drink it
Everyday	1:9.5	199 g	1,893 mL	18–22 h	about 6¼ cups	straight over ice
Strong	1:7.5	252 g	1,893 mL	18–22 h	about 5¾ cups	with a splash of milk
Jet fuel	1:5.3	357 g	1,893 mL	18–22 h	about 7½ cups	cut with a little water or milk
Concentrate	1:4.5	421 g	1,893 mL	18–22 h	about 9 cups	mixed 1:1 with water or milk

If your beans are darker

Darker roasts give up their flavor faster, so they brew at a slightly wider ratio and steep for less time.

Roast	Ratio	Coffee	Water	Steep in the fridge
Light	1:9.5	199 g	1,893 mL	18–22 h
Medium	1:10	189 g	1,893 mL	14–18 h
Dark	1:10.5	180 g	1,893 mL	10–14 h

Don’t stir.
Lid on, into the fridge.

Grind coarse, about the size of coarse sea salt. Find the number for your grinder.

Good to know

The Classic method relies solely on a reusable felt filter, which wants a coarse-to-extra-coarse grind and a gentle, no-stir circular pour — fine grounds or stirring can clog the felt and stall drainage. Toddy explicitly warns 'DO NOT STIR.' It produces a very clean, low-sediment concentrate. (Toddy also sells a paper-filter-bag option for the same container that's more forgiving of grind size and easier to clean, at the cost of slightly more setup.)
