The cold brew is a long process (takes about an hour for each, 5oz cup of coffee). However, this method has the least acidity of any other method, about 60-70% less than a coffee machine. Just please do not compare it to ice-coffee, it is nothing alike. An ice-coffee is a regularly brewed coffee that gets chilled after brewing. Cold-brew is slowly extracted coffee using cold water. Since the process is so slow, it is best to use coarse grinds. You place ice water in the top chamber, some brewers, like ours have an adjustable dripper so you can control the speed. You set it to about two drips every 3 seconds; it might need adjustment halfway through. When it is completely “brewed” you will have a smooth, almost acid-free coffee. For those that usually drink their coffee with cream or milk, we would recommend trying this one black.
Step 1: Measuring
The most flexible part of coffee making, and arguably the one that affects the taste most. For a medium strength coffee, you should measure out 1.75 tablespoons per (5oz) coffee cup. If you’re using whole beans, it will be about 8.75 gram. Use more if you want a stronger tasting coffee.
Tip: The best grind for a cold-brew coffee would be a coarse grind. If you use a finer grind, it might come out a little cloudy, because it takes so long to brew.
Step 2: Adding water
Fill the top chamber with a mixture of ice and water. Do not use too much water as it will not be cold when finished, and do not use too much ice as it will clog the dripper. Try to find an even balance. Spoon your freshly ground coffee into the filter; afterwards, pour some of the water on the grounds to get them wet and start the extraction process. Make sure all the grounds are wet before you start the drip.
Tip: Use filtered water, and freshly ground coffee for the best tasting results.
Step 3: Brewing
Set the dripper to about two drops every three seconds, that’s roughly 40-45 drops per minute. For the best results, it is recommended but not necessary to come back and adjust the dripper, because as the water gets lower on top, it decreases the pressure and slows down.
Tip: You can add a small paper or stainless steel filter on top of the grinds, to help disperse the water better.
Step 4: Finishing up
After about 3-4 hours (if you are brewing the full 4 cups), the coffee should be done. Just remove the top chamber and clean out the filter. Use the carafe to serve or store.
Tip: The carafe comes with a lid that you can just cover it and store.
Step 5: Enjoy your coffee
Just pour into your favorite mug and enjoy the best tasting coffee you ever had. Keep in mind that unlike other brewing methods this is not a concentrated solution, rather you drink it staright without any dilution.
Tip: You can store your cold brew coffee in your fridge for later enjoyment.
