I agree with DNRobert. The cold brewing process makes wonderfully smooth, mellow, but full tasting cold coffee. It is best for Iced Coffee and not as good when heated afterwards. It absolutely has less acidity for your digestive tract. This is different from the acidity we speak of in terms of flavors of the different varietals of beans. In terms of taste it is a matter of personal preference but I think the cold process, or toddy brewing, makes great iced coffee.
You can experiment with it at home with no special equipment. Just use a large plastic rubbermaid container and use about 1 pound of coarse ground beans of your choice to a gallon of water. (I halve this) Dump the coffee in the water, stir and cover it. Let stand 18-24 hours, to taste, then strain out the grounds with any filter available. The metal mesh ones that often come with drip coffeemakers work well. The finer the filtration, the less like pressed coffee it becomes. I like a little body in mine so I use a regular metal strainer. I use 2 parts of this concentrate to one part water and also add ice. Just my ideas in case you are feeling like playing with new stuff.

Good Luck!
