I love my coffee.
Anyone who knows me, knows this.
I have two roasters (liquified air and barrel roaster), two... no three french presses, an Aeropress, a hacked Espresso machine (got rid of the aerator at the bottom of the filter basket), and a Toddy Cold Brew system.
Ahh... young Padawan, you have never heard of cold brew system? Sit at my feet and let me tell you about it.
We are all familiar with the various heat related methods of extracting coffee's delicious goodness from the beans, using a combination of heat and pressure to do so. May of these methods make amazing coffee (aeropress) and some of them only make crappy coffee (I'm lookin at you residential filter basket brewers.)
But one takes 5 minutes to setup, provides a weeks worth of coffee, and reduces the acidity of the coffee by up to a 1/3 of hot extraction methods.
I speak, of course, of cold brewing.
There are many different cold brewers out, there some of them beautiful and expensive but the Toddy is a simple to setup, quick and inexpensive solution.
Basically: Insert filter in bottom, insert cork, alternate coffee grounds and water til everything is in, cover (optional) and lets sit for ~24 hours. Afterwards you pull the cork and drain into the provided glass carafe. Said coffee extract keeps for a week in the fridge with no problems. Well... mine seldom stays around that long...
You can either drink it iced with milk or water, or hot in the place of an espresso shot in a latte or americano.
One thing I have noticed it that cold extraction changes the flavor of certain coffees, which makes sense since some fats and flavorants extract at different temperatures. For example a mellow Mexican I use for drip all the time is grassy and bitter with cold-extract and a Ethiopian which I cannot drink hot-extracted makes an amazing chocolaty cold brew. In fact to test I hot brewed some of the Ethiopian and compared it to the cold-brewed batch which I made into an americano. It was literally like drinking two completely different coffees.
So be warned, you favorites in one method may not be tasty in the other.
