Have you ever heard of Cold Brew coffee?

So how does it work? According to Todd Simpson, time replaces the heat factor in brewing cold brew and that high temperatures release undesirable elements of flavor. Cold water brewing leaves the bitter oils and fatty acids behind.

You make a cold-brewed coffee concentrate and it takes about 12-18 hours to brew and will stay fresh up to 2 weeks. When you are ready to serve, simply use 1 part of the concentrate to 2-3 parts hot water, milk or soy to make as strong or weak as you want.

The cold-brewed coffee maker on his site, Toddycafe.com retails for $39.50.
