I received what has to be the most simple coffee brewing method I’ve ever seen. It is a sock attached to a wire. Not just any sock though. The Coffee Sock is a tightly knitted sock that is perfect for coffee brewing.
I don’t go camping, but if I did this would be an ideal brewing method for someone wishing to keep their pack weight down. But you don’t need to step outside to use the brewer. I’ve been brewing with it in my own kitchen.
#1 Place Coffee Sock into Mug
This brewing method is similar to making loose leaf tea with an in-mug filter.
Place the Coffee Sock into the empty mug.
#2 Add Ground Coffee
I am getting good results using a drip ground. My baseline brewing ratio is 17 to 1 (17 grams of water per 1 gram of coffee). Since you will be making one mug of coffee at a time, figure out how many ounces or grams your mug holds and do some basic math.
I use a kitchen scale, but you could just follow this basic rule.
- A 12-ounce mug of coffee is 340 grams.
- Divide 340 by 17 and you get 20 grams of coffee.
- That little scoop that comes in a can of coffee holds 10 grams.
- So 2 scoops per 12-ounce mug.
- If you have a 16-ounce mug, add another 1/2 a scoop.
- If you have an 8-ounce mug, subtract 1/2 a scoop.
A coffee can scoop holds about 10 grams of coffee.
Add ground coffee inside the Coffee Sock.
#3 Add Hot Water
Bring water to a boil and then let it cool for 10-30 seconds to bring the temperature down a bit. Fill the coffee sock slowly. After adding water, if you notice any clumps of coffee not making contact with water, use a spoon or a chopstick to break them apart. You want all the coffee grounds making contact with water.
#4 Wait About 3 Minutes
On the official site, they use a 2-minute brew time. I got better results with a 3-minute brew time. Experiment. Use what works best for you.
#5 Remove the Sock Filter and Serve
Remove the filter and the coffee is ready to drink.
After 3 minutes, lift the Coffee Sock out of the mug.
The coffee is ready!
#6 Clean Up
Let the filter cool a bit before emptying the grounds into the trash or compost. Turn it inside out and give it a rinse. Set it aside to dry so it is ready for the next use.
