What is a Cold Brew Concentrator?
![]() |
This is simply a device that allows coffee grinds to soak in room temperature water overnight. The device also has a method for draining the resulting liquid through a filter. |
What do I need?
A cold brew device, available from several sources on the links page, coffee, and water. Optionally, you will want either an ibrik or a french press because you will probably not want to drink the result!
What type of coffee grind?
“Regular” or “coarse grind” is what the manufacturer recommends.
What else should I know?
Well, I just tried this after having done lots of reading and research. First let me inform you that I am not a “coffee nut,” or anything. I will even meet friends at Dunkin Donuts and drink their coffee! I like an excellent cup, but will not be difficult about it.
That being said, I don’t understand cold brewed coffee.
I started with a pound of Starbucks French Roast coffee. I ground it somewhere between “drip” and “french press.” Then I cold brewed it for 13 hours. When we (I don’t do these things alone) tried it diluted 3:1 (water to concentrate, the “recommended” ratio), there was really no taste at all! At 2:1, it tasted like really insipid coffee-water. At 1:1 we knew it was coffee, but still, no taste, no zing, no zip.
Step 1:Place the plug into the bottom of the cold brewer. |
Step 2:Wet the filter with water until it is pliable. Place it into the filter recess in the bottom of the brewer. |
Step 3:
|
Step 4:
|
Step 5:Wait 12 hours or more. They say you can wait up to 24. |
Step 6:While holding the brewer over a decanter, pull out the plug and place the brewer onto the decanter. |
Step 7:
|
Step 8:Toss out the grinds. Either refrigerate or toss out the concentrate. |
Step 9:Apologize profusely to your guests, grab a french pot, and follow these directions. |

Place
one pound of “regular” or “coarse ground” coffee into the brewer.
Slowly
pour 4 cups of cool water onto the grinds. Wait 5 minutes and slowly
pour 5 additional cups of cool water on the grinds. Do not stir.
Wait
for the concentrate to filter through. This can take up to 20
minutes.
