i use to work for a blue bottle coffee spot in sf, the village market, there we made some of the best cold brewed coffee i have ever had. frontier natural sells a lb (16oz) bag of chicory, for around 20.00 on amazon. i highly suggest it or if you live near a great co-op (briar patch, rainbow grocery, davis natural) you might be able to find it in their bulk section or they can order it for you.
1 pound coffee beans, coarsely ground (blue bottle retrofit works great, your favorite high quality darker coffee single origin or blend).
1 1/2 ounces chopped, roasted chicory
10 C filtered cold water
add the coffee & chicory to a large stock pot. using a wooden spoon, stir in the water until well mixed, cover and let sit in a cool place for 10 – 12 hours, this will make you a syrupy concentrate.
once steeped strain the coffee using a fine mesh strainer, into a large iced tea jar or 1.5Q mason jar. I like using an iced tea jar with a spout, easy to pour and you won’t waste a drop!
you can experiment with how much cold water you add to each cup of iced coffee. blue bottle suggests a 1:1 ratio. I like a little less water, but i compensate with fresh almond milk (recipe to come) and a little simple syrup (blue bottle suggests 3oz of simple syrup to the entire 1.5Q+/- coffee concentrate.
the concentrate will keep for a week in your fridge.
this is the the most clean coffee you will ever have. if you have a sensitive stomach to coffee, this may be the answer as the coffee oils aren’t extracted by hot water, the slow long process produces a sweet, strong, uber delicious cup of coffee.
