Cold Brew
Cold brew is one of the easiest and cost-effective ways to make several cups of delicious coffee, which can be kept in the fridge for days. Cold brew, as the name suggests, is never exposed to heat. Steeping coarse ground coffee in cold water for 12—24 hours produces a light and delicate beverage, low in acidity, designed to be served over ice or with your choice of milk.
You will need
-
Hario 600mL Cold Brew Pot
-
Adjustable burr grinder
-
Scales
-
50g fresh Kōkako coffee
-
600g cold filtered water
Instructions
-
Grind your coffee to a coarse plunger grind. Add the ground coffee to the mesh filter, and place inside the glass flask.
-
Add 100g of cold filtered water and stir gently to ensure all the coffee grounds are saturated. This is to “bloom” the coffee.
-
After stirring, slowly add 500g of water and put the lid on the flask. Leave it to steep for 12-24 hours in the fridge.
-
Once the coffee is finished steeping, remove the filter and put the grinds in the compost. Thoroughly clean and dry the filter so it’s ready for next time! Your cold-brewed coffee is now ready to enjoy, and it will keep in the fridge for 4-5 days.
For a 1l cold brew maker, follow this same guide, but using 85g of freshly ground coffee to 1l of cold filtered water. Bloom with 200g of water, then add the remaining 800g.
Extra tips for the best results
-
Use high quality, fresh ground coffee beans and filtered water for best results. But if you don’t have access to your own grinder, get your coffee pre-ground to a coarse plunger grind.
-
Add water in a slow, controlled way and don’t allow the coffee grinds to sit too high up in the filter, ensure they are all submerged.
-
If you find a lot of sediment at the bottom of your brewer once the coffee is brewed, you will need to make your grind size coarser to eliminate fines getting through the filter.
-
For best results, infuse the coffee for a minimum of 12 hours, and a maximum of 24 hours — you can adjust this to your own taste.
-
If you have a 1l cold brew coffee pot, use 80g coffee to 1L water and follow the same method.
-
You can also make this cold brew with a non-Hario cold brew maker, by following a 1:12 coffee to water ratio.
