Something I haven't tried yet (just moved, apartment is hopelessly disorganised), but sounds good.
On one of my mailing lists, one guy asked:
Anyone tried the cold brew?

Steeping 1 pound of freshly ground coffee with 9 cups of water for 12
hours make IMHO the absolute best coffee you can make. It's concentrate
that you refrigerate and because you aren't using heat against the beans
oils don't leech out of the beans and thus the bitterness is cut way
back. It's a wonderful yet odd surprise not to taste that "bite" after
you sip it. It even makes 8'oclock brand coffee taste good. Freezing
small cubes of it for iced coffee drinks will insure that your drinks
don't get watered down as it melts.
It's important to remember that using heat to make coffee is a European
concept and the indigenous folks in Central and South America have been
making it like this for thousands of years.
If there is ONE big benefit though, it's that people who suffer acid
reflux can drink coffee again! It's true, since the pH balance is lower
it's WAY easier on the stomach. I know this because I used to sufffer
horrific reflux and now I can drink coffee again and it doesn't bother me.
I still drink quad caps when I travel and counter with eating tropical
tums like candy.
