No-electricity coffee maker takes patience
Take a look at this coffee maker. I saw it on dvice.com. Coffee takes 12 to 24 hours to brew.
But, in exchange for waiting, maker claim you get better tasting coffee.
The contraption uses cold water, which tests show, reduces acid by 69.6 percent. Acid is what sometimes makes coffee taste bitter. Also, retained are essential oils that are lost when coffee beans are heated, further enhancing the flavor.
The hourglass does not use electricity -- it's all infusion. Coffee + water = coffee extract. Take the extract, which lasts two weeks in the frig, and mix with hot or cold water.
Is this all may be too much for our instant gratification society? You sticking with the regular pot, or sticking with the coffee shop?

This devise costs around $70 and is very easy to use. Cold filtration coffee has been around for a long time. At our company, Mt. Hood Roasters Coffee Company, we sell the Filtron cold filtraion coffee brewing system which is considerably cheaper at $ 39.95.
The process of cold filtration is very easy to do but there are a couple of things you need to remember.
1. The coffee must be ground to a very course consistency. I wouldn't recommend buying ground coffee in a bag as it will not be course enough.
2. The filtration system creates a coffee syrup. The syrup is added to water or hot milk at a ratio of about 3:1 water:syrup. The instructions say 4 or 5 ounces of water to syrup but that will be very week.
3. The coffee produced has almost no tannens so is very smooth. The taste is a coffee taste but a little different than what one might be used to. I have found that it is good for 1 cup but too rich for multiple cups.
4. This process is ideal for summer iced coffees.
For the coffee fanatics out there...this is one of several items you may want to have in your coffee tool kit. I have had a lot of fun with it as the syrup can be used for brewing "coffee porter beers," added to food recipes, to make liquers, and as a base for bar drinks.
Try it...you will enjoy it.

Meredith, the overnight wait is worth the reward of delicious, smooth-tasting coffee. I can hardly abide any other kind. I love making a latte with 2 oz of extract and a half cup of steamed milk. Ice coffee's wonderful too for those too-hot-for heated coffee.
I'm happy to wait for my cold brew, plus once it's brewed, I've got enough for a week--what's not to love?

The cold brewing does reduce acidity but you can also make hot coffee in about 2 minutes with an AeroPress that also reduces acidic levels. The acidity isn't a bad thing, though, unless it bothers people's stomachs. Also, different coffees from various regions and countries have more acidity than others so just by using coffee from different regions can reduce acidity.

Want to be even greener and more frugal? You don't need to buy this. Google cold brew coffee, get a couple pint jars and do it yourself.
