I know what you're envisioning. Grabbing what was a piping hot mug of coffee and taking a swill, realizing, only once it's touched your lips, that it's gone cold. Gone stale. Gone downright nasty.
This is not that.
Cold brew coffee is brewed completely differently than hot coffee. In hot coffee, hot water is forced through coffee grinds and a filter, increasing acidity and altering the chemical composition of the coffee beans themselves. In cold brew, you simply soak the coffee grinds in cold water, let steep from 12-24 hours, and store the concentrate in the fridge for consumption.
This cold and slow method of brewing the coffee actually brings out different flavours in the coffee than hot brewed coffee. The cocoa flavour is often more pronounced and it has a smoother finish with less bitterness.
I've been trying to convert everyone I know to cold brew. Ha.
I've called it concentrate in this post, and that's really what we're making, a cold brewed coffee concentrate. I personally don't water it down, I add as much ice as I can fit in my cup, and add some cream. I usually only brew my coffee for 12 hours, I find that's when the taste is the strongest, and I don't have to water it down. Longer than that, I need to water it down because it gives me the caffeine jitters.
