How to batch brew cold-brew coffee

When the temperature rises, it's time to start serving cold brew! In this quick power-up training we explain how to make a batch of cold brew coffee in your cafe or restaurant. Below you'll find a guide to different methods of making cold brew, a step by step guide and some useful recipes to try in your cafe, bar or restaurant.

GET READY TO BREW: THINGS YOU NEED FOR COLD BREW COFFEE

CHOOSE THE RIGHT COFFEE

Choose a coffee with plenty of body and sweetness, these flavours extract best in cold water brewing. We like Central and South American coffees for cold brew. Try Project Peru which comes in pre-ground and weighed sachet, or a lighter espresso like Dr Strangelove.

Avoid coffees with high acidity as these flavours are lost in a cold water brewing method.

EQUIPMENT

A cold brew system like the Brewista Cold Pro system makes large batches of cold brew much easier to make.

The stainless steel metal filter can be lifted out to drain and the dual filter options means you get a clean brew straight from the brewer. The smallest brew using this system is 8l and the largest is 12l.

TIME

You need to pre make your cold brew 1 day in advance. We recommend an 18-24 hour steep for half-size brews and 24-36 hours for full-size, concentrate brews.

Your cold brew will keep for approximately three days in a fridge.

CONCENTRATE VS DILUTED COLD BREW COFFEE

Cold brew concentrate is a great way to maximise the flavour, increase versatility and reduce the volume of cold brew coffee you need to store.

To serve, just dilute to order with ice & still or sparkling filtered water, milk or tonic. Cold brew coffee concentrate also works well in alcoholic coffee cocktails as it's strong enough to battle with the other flavours you’re adding.

A diluted brew is great for serving straight up with or without ice. There is no need to dilute with extra water. This speeds up service time as you don’t have to factor in other ingredients.

We recommend using a diluted cold brew coffee recipe to run through nitro coffee systems.

1

Set up your filter and strainer

First, ensure you fit the nylon filter to the inside of the tap and fit a fresh paper filter to the strainer basket
2

WEIGH OUT AND GRIND COARSLEY

If you're brewing with whole bean coffee like Dr Strangelove, weigh out 1300g of coffee and grind this coarsley as you would for cafetiere and add to the filter.

If you're using pre-ground sachets like Project Peru, add 11x120g sachets to the filter
3

POUR, STIR & STIR AGAIN (and AGAIN!)

Pour 8 litres of cold filtered water over your coffee and stir well to ensure all the coffee is saturated. Stir again after 10 mins, and again after 1 hour.
4

STEEP FOR 24hours

Fit the lid and leave to brew for 20-24 hrs in a cold room or fridge.
5

STRAIN & DECANT

Lift the filter basket to strain. Be patient - straining can take up to 1 hour! Once strained, open the tap and decant your filtered coffee concentrate into clean bottles (this recipe makes approx 5.3 litres). Your cold-brew coffee concentrate should be kept chilled and can keep for up to 3 days.
TIP

KEEP IT CLEAN

Make sure you clean the equipment thoroughly. Old coffee tastes bitter and unpleasant. Clean equipment will make your cold brew taste far better. The round nylon filter is reusable but you must rinse & dry thoroughly.
