HARIO 1-Piece Acrylic Water Dripper, Clear

I'm generally happy with this product overall, although so far I've only used it a few times. Here are a few minor critiques:(1) As another reviewer pointed out, the flow rate does tend to diminish after some amount of time, at which point the valve needs to be readjusted in order to keep the water dripping. In one case I failed to readjust it before going to bed, and the next morning I woke up to find ~100 mL of water still sitting in the upper chamber, with no movement at all.(2) The rubber nub that attaches to the upper chamber for the water to drip through never seems to adhere to it very well. When I'm moving the valve to adjust the flow rate, it always feels as if the whole assembly is about to fall apart. To Hario's credit, it hasn't happened so far though.(3) I also own the Hario Mizudashi immersion cold brew maker, which is much cheaper. Supposedly drip cold brew makers do a better job of preserving the brighter, fruitier flavors, but so far I haven't noticed a difference. I like the coffee that this makes about as much as I like the Mizudashi coffee. Go figure.

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.

水を落とす量・速度により数時間かかりますが、ゆったりした時間がながれます。出来上がったコーヒーは間違いなく美味しいです。耐熱性能は…水出しなので必要なのかわかりません。洗う時に男性の手のサイズでは中に手が入らないので、ボトルブラシが必要でした。

It is impossible to adjust the drop speed using the cheap valve - it’s either too fast or too slow. Returning and ordering a Gina that I bought for my friends and tested already.

Ich hab schon viele Hario-Produkte; die sind meistens deutlich teurer, aber auch deutlich besser als die anderen. Mit diesem Cold-dripper bin ich sehr zufrieden. Bei vollen 6/7-Tassentank muss man am Ende (1,5 Tassen Rest) den Hahn vielleicht nochmal nachregulieren, weil das Wassergewicht von oben ja nicht mehr da ist. Sonst würde der Rest zu lange dauern. Ansonsten sind alle Teile wie immer sehr hübsch und hochwertig, wie gewohnt.
