Best cold brew coffees for an instant caffeine fix

For those that take their coffee seriously but want something more refreshing for the warmer months, cold brew is the summer drink of choice.

Not to be confused with iced coffee, which is made with hot water and then cooled down – cold brew is a much slower process, created entirely with cold water and a bit of patience.

Think of it like an infusion, where you leave finely ground coffee to macerate with cold water for several hours, generally between 12 to 24 hours (there’s no definitive amount of time, it varies from brand to brand).

It’s a super simple process with no electricity required, the key element to getting the best brew is quality beans. Look out for speciality grinds and single origins if you’re after something special.

Because you’re not flash heating the coffee, this slow extraction results in a smoother, sweeter and less acidic drink – yet with all the complexity you’d find in a fantastic cup of coffee.

This slower release of caffeine, along with the lack of heat, means it’s up to 60 per cent less acidic than a traditional cup. Those who have a have a hard time with coffee due to heartburn or jitteriness should find cold brew much easier to drink.

We put a selection of brews to the test – including those made with sparkling water, single serves and large 3l “bag in a box” versions.

When choosing the best cold brew for you, consider how much you’ll anticipate getting through. Some of the larger options will need to be consumed within about four weeks to preserve the freshness.

Keep it in the fridge for instant cooling refreshment and serve over ice. We like it black, but you can also add any milk – regular or plant-based and use it to create any coffee drink or even smoothie.

Less bitter and naturally sweet, cold brew also makes the ideal base for cocktails – particularly the much-loved espresso martini. It makes the process so much easier too, negating the need for cooling down hot coffee in a shaker.

We found it really upped our espresso martini making game and if you’re making drinks for larger groups or at a party, we’d go so far as to say a bag in a box cold brew is essential.

With us all working from home a little longer, make sure your fridge is fully stocked with the best selection of cold brew.
