After biking to work on humid summer days, the last thing we wanted was a hot cup of coffee. But like most folks, we needed something to get us going in the morning. Making ice coffee the usual way (with a coffee maker or French press over ice) uses energy, requires added equipment, creates unwanted heat and even cracks the occasional pint glass! We were at a loss until last month, when a friend told us about cold brew coffee...Cold brew coffee requires nothing more than some ground coffee grounds, an old spaghetti jar, a filter of sorts and some planning ahead. This method works great with just about any coffee and produces a wonderful flavor, without the bitterness associated with less expensive beans.
There are a few recipes online with conflicting coffee-to-water ratios, but in our experience, just about any combination of coffee and water, left over night in the fridge, seems to work! We typically put a quantity of medium-course grinds in a spaghetti jar, fill it up with water, shake, and let it sit for a couple days in the fridge. When you're ready for a cup, simply filter it through a coffee filter, or a fine strainer, dilute to taste, and enjoy over ice. We also like to try fastening some cheese cloth over the jar for an instant as-you-pour filter. If anyone tries this, let us know if it works!
For those who prefer a more precise recipe, here's one compliments of The New York Times:
1. In a jar, stir together 1/3 cup (medium-course grind is best) coffee and 1 1/2 cups water. Cover and let rest at room temperature overnight or 12 hours.
2. Strain twice through a coffee filter, a fine-mesh sieve or a sieve lined with cheesecloth. In a tall glass filled with ice, mix equal parts coffee concentrate and water, or to taste. If desired, add milk.
