Some coffee aficionados say cold-brewed coffee becomes oxidized when it sits in the fridge, unlike the Japanese method which freshly brews each cup. Basically, the method involves making a pour-over cup of coffee, replacing about half of the water with ice, which goes directly into the brewing vessel. The hot coffee drips over the ice as it brews, melting the ice and quickly cooling down the liquid.
I gave the method a try in my Chemex coffee maker and was happy with the results; the iced coffee tasted fresh and balanced, and was just the right strength. This method doesn't seem very revolutionary — isn't a lot of iced coffee just extra-strong coffee poured over ice? — but making more careful measurements when replacing water with the equivalent amount of ice seemed to pay off. And brewing directly onto the ice is just smart.
Did it taste better than cold-brewed iced coffee? I didn't think so. But it took much less time to make and is undoubtedly a great last-minute iced coffee alternative to cold brew.
