This cold brew style
Low acidity, soft entry
Dark roasted coffee brewed cold for a lower-acid, smoother drinking experience.
Light bitterness, clean finish
Cold extraction keeps bitterness gentle, with a clean and easy finish.
Light caramel and roasted aroma
Not a fruity cold brew. Expect light caramel sweetness, gentle roasted aroma, and steady coffee character.
Black coffee or milk coffee
Enjoy it as black coffee for a clean cold brew, or add milk or oat milk for a rounder cup.
3 simple cold brew steps
Add the coffee bag
Place one cold brew coffee bag into a cup, bottle, or cold brew jug.
Add 300ml room-temperature water
Pour in about 300ml room-temperature water and make sure the coffee bag is fully immersed.
Chill for about 8-12 hours
Refrigerate for about 8-12 hours, then remove the coffee bag and enjoy.
Everyday drinking moments
Busy mornings
Prepare it the night before and enjoy it the next morning without brewing on the spot.
Office iced coffee
No coffee machine and no grinder needed. Easy to keep in the office fridge.
Cold drink at home
Low acid and low bitterness make it smooth and refreshing for hot days.
Prepare before heading out
One bag makes around 300ml cold brew, ready to pour into a travel cup.
How does it taste?
Expect light caramel sweetness, gentle roasted aroma, and a smooth mouthfeel. It is not a bright fruity cold brew, but an easy-drinking dark roast cold brew for daily black coffee.
FAQ
Does it have to be refrigerated?
Yes, refrigeration is recommended. Cold brewing in the fridge gives a cleaner taste and is better for iced coffee.
Can I brew it for more than 8 hours?
Yes. Around 8 hours gives a lighter cup, while 10–12 hours gives a stronger coffee character. Remove the coffee bag after brewing.
Should I remove the coffee bag after brewing?
Yes. Remove the coffee bag after brewing to avoid an overly strong taste or unwanted flavours.
Can I add milk?
Yes. If you plan to make milk coffee with milk or oat milk, brew for 10–12 hours for a more concentrated coffee taste.
Can I use cold water directly?
Yes, but room-temperature water helps extraction start more evenly before refrigeration.
