How to make cold brew

Get matched with the perfect coffee for your cold brew.

How to make cold brew is a question that is being asked more and more as the drink comes into fashion. Cold brew is great, because it’s simple to make and lasts up to a week. So you can make a brew on Sunday and add hot water to it every morning to have a strong cup of coffee every day for the entire week. Ingenious

Fresh Beans for Cold Brew

Before we get started, there’s one thing everyone needs in order to make the perfect cold brew, and that is fresh coffee beans

You can’t get anywhere in life with stale, old, crusty coffee beans, and that situation happens around two weeks after roasting. So get yourself to a roaster and purchase the best beans money can buy. 

Or if you’re looking for an at home solution, buy some beans from Bean Merchant, and we’ll send them to you from a selection of New Zealand’s best roasters. We’ll even give you our quiz so that we can deliver quality beans that are catered to your tastes.

The Cold Brew Recipe

Recipes for cold brew vary. Some think that a ratio of 1:2 coffee to water is good, whereas others suggest that a ratio of 1:5 or even 1:8 is best. This is for a cold brew concentrate though that you would then mix with milk or water. Some suggest that if you don’t want to make a concentrate and want to just drink it straight, you could use 1:17 or 1:18. All I know is that it’s down to personal preference. Like strong coffee? Go for a lower ratio. Like weaker? Go for a higher one.

A ratio of 1:8 means if you’re using 8 parts water, use 1 part coffee. So if you’re making a cold brew of 500ml of water, you’d mix it with 62.5g of coffee. 

Step 1.

Grind your coffee at a coarse grind setting.

Step 2.

Pour your coffee into your vessel of choice (in our case, our plunger).

Step 3.

Pour your water into your vessel of choice.

Step 4.

Give it a stir.

Step 5.

Slap a lid on it.

Step 6.

Put it in the fridge for 24 hours. 

Step 7.

Filter the liquid off the coffee grounds – through a tea towel, or a chemex filter, or your plunger if you’ve used this. Put the liquid into a bottle or container to keep it in the fridge. It’ll last up to a week. 

I told you it was easy, I don’t even know what more to write about this…

Now you know how to make cold brew.

Delicious.

WARNING:

Be aware that your cold brew coffee will be VERY strong. It’s more like a coffee concentrate. You can drink it straight, but you’ll probably want to add some water to it. If you want a hot drink, add some hot water. If you want a cold drink, add some cold. You can add some ice, and milk, and some syrupy stuff and make yourself an iced coffee if you’d like to. Ice cream would even go well with it.

Seriously though, before you make cold brew...

I can’t stress enough how important fresh beans are, and that they are catered to your tastes and brew method.
