Home made cold brew
As promised, here is an easy home made cold brew recipe just in time for the bank holiday!
In my opinion, cold brew coffee is far superior to iced coffee any day of the week! If you haven’t yet tried a cold brew then get yourself down to decent coffee shop, Starbucks, Selfridges, or buy online through Amazon or Ocado. They are incredible, the depth of flavour and natural sweetness is unexpected, which makes cold brew that extra bit special. A lot of iced coffees can taste quite bitter, hence why people quite often top them up with syrup. This bitterness comes through as the coffee is extracted hot in espresso form before being cooled over ice. However, with a cold brew coffee, grounds are left to steep in cold water for up to 24 hours. No hot water is used in this process which creates a much gentler extraction of the flavours and oils in the coffee grounds.
Cold brew is said to be less acidic than a regular hot coffee. Whether this is true or not is still up for debate as coffee beans from different regions naturally have different acidity levels to begin with. Nonetheless, if you were to brew 2 coffee’s, one hot and one cold, using the same coffee beans from the same farm and harvest; the cold brew coffee is more than likely to be less acidic due to the gentler extraction process.
There are numerous ways to brew your own cold brew, and there are even cold brew kits you can buy. We at Singl coffee are simple souls though and are all about the ease and convenience. Therefore, to make our simple cold brew all you need is the following…
- A Jar/Jug (Preferably with a lid. If not a bit of cling film will do)
- Kitchen scales
- Whole coffee beans
- A Grinder
- Water (Bottled or filtered)
There are 2 reasons we have used whole beans. The main one being you need a course grind for a cold brew. If your coffee is ground too fine it will over extract, this means all those acids and oils will overpower the final product and create a sour bitter final cup. They will also be a pain in the arse to filter out, resulting in a dark murky mess in your cup.
If you don’t have a grinder, try a food processor.
The beauty of cold brew is that your coffee grind doesn’t have to be perfect and uniform, it is rough and ready! A course grind is like breadcrumbs, or the last part of your cereal box where all your cornflakes have been smashed to bits!
Finally, water; If you live in an area with hard water I suggest using a Brita filter to filter your tap water, or buy some bottled water. As water is the main ingredient and key to extracting the coffee, you don’t want any added flavours or contaminants affecting your brew due to poor water quality.
1. Measure out your coffee. We used 100grams whole beans.
2. Blitz your beans in the grinder for a few seconds. It won’t take long to grind the beans, so don’t turn on the grinder or food processor and walk away!! Literally 5 seconds and they will be perfectly ground!
3. Tip your grounds into a jar or jug.
4. Place the jar onto the scale and fill with 500ml water. We are working with a 1:5 ratio of beans to water. 100g beans to 500ml water. (The eagle eyed ones amongst you will notice we went over by 4ml Ooops my bad!)
5. Give it a good mix, pop on a lid and place in the fridge. If you don’t have a lid, then cover with ling film. The lid helps protect the coffee from being flavoured by anything in the air in your fridge. At the time of making our cold brew, we had half a left-over onion in the fridge. Onion coffee? No thanks!
6. After approx. 20-24 hours remove from the fridge and pour the coffee through your sieve into a measuring jug. This removes all the large pieces of coffee grounds. If your coffee still has grounds floating in it, pour it back through the sieve a second time, or even use a tea strainer to catch the finer particles floating in the brew. The more you sieve the brew, the cleaner and clearer the final cup will be.
7. Pour a small amount into a glass and taste. If the coffee is too strong, you can dilute it slightly with some more cold water to suit your taste.
Remember, as with all coffee, the coffee beans you use matter a great deal! They can dramatically alter the taste of your final cup depending on what type they are, so don’t skimp and buy cheap nasty beans!
If your brew still looks cloudy, pop a filter paper into your sieve and strain the coffee through this again. It will remove all the very fine coffee particles. You will get a super clear brew that won't get bitter over time.
As always, if you try out your home brew, tag us in your pics on social media and we will share them out!
Happy Brewing! x
