Cold brew ratios

Grounds to cold water, by the cup. Everything else about cold brew is patience, so this is the only page you need.

The house recipe, per litre ¾ cup

Approximately ¾ cup of cold brew grounds to 1 litre of cold water, steeped in the fridge for twelve to sixteen hours. That is the recipe that ships with every Brew and Go.

Our team all use varying amounts, so treat ¾ cup as the middle and move a spoonful either way.

Pick your strength

Same method, different amount of grounds. Black is gentler; the stronger recipe is built to take milk.

The lightest we would go. Beautiful black or over ice, but it will disappear under milk.

One litre is a full Brew and Go: ¾ cup of grounds, a litre of cold water, twelve to sixteen hours in the fridge. Four glasses at around $1 each.

A full cup of grounds makes a brew strong enough to take milk without thinning out. Steep no longer than fifteen hours or the sweetness goes flat.

Pouring it out

01

Black, over ice

Fill the glass with ice and pour the house brew straight over. The melt does the only dilution it needs.

02

Iced latte

Brew the stronger recipe, a full cup of grounds, then top with milk. Oat holds up best against the chocolate and red wine in Daily Diva.

03

Long glass

Top the house brew with soda for an all-afternoon drink. A wedge of orange plays to the citrus in Decaf Diva.

Two things that change the recipe

Grind, Coarse As Raw SugarBoth blends arrive ground for cold brew, which is why the cup measures above hold. Grind your own finer and the same cup comes out heavier.

Time, Twelve To Sixteen HoursTwelve to sixteen hours is the window, and never past fifteen for the stronger recipe. Steeping longer is not a substitute for more coffee.

A measuring cup is all you need

The recipe is written in cups on purpose. Scales are more accurate if you have them, but ¾ cup of grounds and a litre of cold water gets you there every time.
