Among New Orleans’ many food secrets is cold-brew coffee. It’s as low-tech as you can get: no coffee maker, French press or special equipment is needed. Heck, you don’t even need electricity. Just combine coffee grounds and cool water in a bowl. After 12 hours, strain the solids out, and iced coffee is at your call — no extra chilling required. Yes, you need the long soak, but prep it before you go to bed, and coffee will be waiting for you in the morning. Once you try it, you’ll see how backwards it is to brew coffee with hot water and then wait for it to cool down.
“Heat brewing releases acids and oils, and as the coffee sits in the refrigerator, the bitterness intensifies,” according to a NY Times Magazine article. Cold-brew coffee is 67% less acidic, making it smooth, rich and naturally “sweeter.”
Cold-brew coffee concentrate
Cold-brew is so common in New Orleans that you can buy syrupy coffee concentrate at neighborhood supermarkets, as well as Whole Foods.
For better or worse, I can now enjoy coffee! For the longest time, regular cups would dehydrate me like crazy. I switched to decaf, and still no dice. The culprit, as I found out, wasn’t caffeine. It was the acid. I also would take my coffee unsweetened, since sugar somehow made it sour (the exception: coffee from Dunkin Donuts and Oaxaca, Mexico). Again, the culprit was the acid.
For an authentic experience, try a coffee-chicory blend from Cafe du Monde, French Market or Blue Bottle Coffee company. During their civil war, the French ran short on coffee, so they used chicory as an extender. Chicory is the root of the endive plant. It tastes chocolatey, is caffeine free, cleanses the blood and improves your liver’s health.
Cold-Brew Iced Coffee Recipe
Prep Time: 10 minutes
Total Time: 12 hours
Yield: 1 1/2 cups coffee concentrate
Serving Size: 1 cup
Ingredients
1/5 pound dark roast coffee and chicory, medium ground (about 1 cup)
2 cups cold water
Ice
Milk
Instructions
Put coffee in a nonreactive container, like a stainless-steel bowl. Add 1/4 cup water, stirring gently to wet the grounds, then add remaining water, agitating the grounds as little as possible. Cover and let steep at room temperature for 12 hours.
Strain coffee concentrate through a medium sieve, then again through a fine-mesh sieve.
[As I've seen it made, most people use a reuseable mesh bag, ultra-fine, you can probably find it in decent grocery stores, def. at gourmet shops/restaurant supply shops]
To make iced coffee, fill a glass with ice, add 1/4 cup coffee concentrate and 3/4 to 1 cup milk, then stir. To make café au lait, warm 3/4 to 1 cup milk in a saucepan or microwave, then pour into a mug and add 1/4 cup coffee concentrate. (Concentrate will keep in the refrigerator for up to two weeks.)
