The following method for brewing iced coffee is from the New England Coffee website.
When brewing coffee to be used as iced coffee, we recommend you brew a half pot at double strength. Place enough coffee grounds in the filter to brew a full pot of coffee, but only add enough water to brew a half pot. The double strength ensures that when the coffee is poured over ice, it will retain its flavor without becoming too diluted.
Start by using two rounded tablespoons of freshly ground New England® Coffee per 6 ounces of water. For the very best flavor, brew New England® Coffee using the drip method. Use only cold water, filtered if necessary, when brewing.
Once the coffee has finished brewing let it cool to room temperature. Then take a 10 ounce glass, fill it with ice and pour in your 6 ounces of double strength coffee. Sip and refresh!
Make a half pitcher of iced coffee to keep in your refrigerator! Follow the brewing instructions above. Once the coffee has reached room temperature, pour coffee into a pitcher that has a closeable lid. Uncovered coffee in the refrigerator will absorb other odors. Place the pitcher in the refrigerator to keep cold. When you are ready for a refreshingly cold glass of New England® Coffee Iced Coffee, simply pour over ice. Sip & enjoy.
Use coffee flavored ice cubes! Follow the brewing instructions above. Once the coffee has reached room temperature, pour coffee into ice cube trays and put in the freezer. Once frozen, use these cubes instead of regular ice cubes to ensure a stronger, more flavorful glass of iced coffee every time!
