I'm a bit of a coffee snob, and my favorite preparation is iced coffee.Having tried this method of brew before, I knew it was outstanding and hoped the Hario dripper would help me reproduce it at home.It did not disappoint. The coffee is flavorful and the preparation opens up dimensions of flavor that completely burn off under the hot-brew-then-ice method.I want to share some problems/solutions that are easy to overlook:The first issue I faced was getting the drip rate right. I researched this and found that one drop every 1.5 seconds was recommended (2 drops every 3 seconds). I would shoot for one drop per second. Set it before you go to sleep and it will be ready by morning. In my opinion, the yield is not a concentrate, and I drink it straight.The second issue was that the water stopped dripping with about 1/6 of the water remaining in the tank. I realized that the dripper spigot is so small that the bubbles in the water I was using were clogging it. I switched the water source--used tap instead of filtered--and the problem resolved.Finally, I heard someone else mention this, and I would have completely skipped it had I not read the instructions thoroughly: you must moisten the grounds prior to turning the dripper on. Just a quick splash of water and a stir will do the trick, but if the grounds are not moistened, I've heard horror stories of water backing up and overflowing.
