Proper Coffee Cold Drip

We've seen some long brewing times before, but 12 hours seems a little excessive, even for cold drip. Yet that's the brewing time for the Proper Coffee Cold Drip ($400). Promising a smooth, flavorful cup of joe, the Proper Coffee brews at a glacial 43 to 47 drips per minute, 1000ml at a time, through an all-glass system of reservoir, filter funnel, and bottom vessel that's elegantly suspended by a water jet-cut aluminum frame. Luckily, you can store the resulting sweetness in the fridge for up to several weeks, so you won't have to plan a half-day ahead just to get your caffeine fix.
