Even though the kids may be heading back to school, summer is still here and so are the warm temperatures.   Some people have been asking how they can make iced coffee at home to cool down.  We listened and experimented to find recipe starting points for coffee concentrates.   You may be asking, "coffee concentrate?".   Ice will significantly dilute the coffee, so you need to start with strong coffee in the first place to allow the flavor to stay strong.  As a general rule, you make iced coffee from a brew double the strength of your normal coffee.&nb
