The WONDERFUL thing about COLD BREWED COFFEE is it is quite less acidic than your normal cup of joe.
cold-water brewing process extracts the natural, flavors of coffee. The result: A bold, super-smooth taste that's easier on the stomach. From a comparison report from Intertek Caleb Brett Process Chemistry Laboratory it was shown that cold brew is 2.45 to 4.47 times less acidic than coffee brewed the normal way.

There are MANY different ways I have either heard of or found listed on the internet, of ways to cold brew coffee. Through a few trials myself I have come up with what I find to be the most consistent and easiest way to do so. So what you will find here is the way I do it and how I do it with a purchased system and my own little trick using old coffee canisters.
The pictures show a Ronco Brew System. Which I found Amazon for under $5.00 (lucky). But it is very similar to the Toddy T2N Cold Brew System that I was told of when I was introduced to Cold Brewed Coffee. Each system works the basic same way and to be honest with you… they are nothing but containers with holes and stoppers in the bottom and a place to place a rather thick felt filter into.
There is no AWESOME SCIENCE to the systems, as you will see when I use a coffee canister I have sitting around the house.
Toddy Has their instructions on a page of their site selling their system. http://www.toddycafe.com/customerservice/instructions.php and let me tell you this. If you don’t have all your ducks in a row, the moon is full and the egg standing on its end… You will make a nice MESS while trying to brew coffee the way they describe… After the 3rd time of cleaning out my filter and pot, I said there has to be a better way! And I have found what I believe to be one of the EASIEST WAYS!
So what you need is a Cold Brew system, either purchased or make one for your self. OR a coffee can and rubber bands…
Step 1: Step 1
Grind your coffee more on the course side. The Ronco system just says “Use your favorite Coffee” I say use coffee beans and grind them! This gives you the fullest flavor I have found! As you see in the picture I do not use a coffee grinder ( I have one, but this is THE FASEST way and it WORKS!) I use my Black-N-Decker Blender. I place 2 cups of FRESH beans in it and turn it on low. Pulsing ever now and then to get the beans moving down faster.
