Hario Mizudashi Cold Brew Coffee Maker - 1000ml Large Capacity, Durable Glass & Plastic, Easy to Use Iced Coffee Brewer for Home, Office, or Travel - Black

First, 600mL is the size to buy because the filter touches a larger surface area of water (unlike the larger size).Second, this is a super easy and practical pot. The filter cleaning was a cinch by hand, no special sponge necessary. I used a glass cleaning brush for everything else.Third, this is wonderful for your health as it reduces the acidity of coffee by 65%. I had acute gastritis for one month and cut out coffee. I'm fine now, but to be on the safe side I switched to cold brew coffee and my stomach is calm and happy :) Even if you don't have stomach sensitivity reducing overall acidity in your diet is good for longevity and good health.Fourth, the taste is superb! There's a natural sweetness, an intensity of flavor and a smoothness as compared to hot brewed coffee. I've been using 100% kona coffee ground and it's just sooooo good.Fifth, the price with this seller is excellent AND all parts are Made in Japan.There are 2 downsides you should note: (1) you need quite a bit more coffee ground and (2) there is more caffeine in cold brew coffee. Caffeine in moderate amounts is good for you; it increases metabolism, aids digestion and helps with heart attack prevention. Still, those sensitive to caffeine need to be cautious.SIX MONTH UPDATE:My Hario pot is in excellent shape after half a year of continuous use. The filter is sturdy and stain free. Unlike hot brewed, cold brewed coffee stays fresh for up to 2 weeks in the fridge (!). I suggest you test the length of brew time to suit your taste: I like a richer concentrate, so I soak the ground for 2-3 days, which is considerably more than the 12-24 hours the manual recommends. Also, experiment adding spices in with your ground. I prefer cardamom-infused coffee. Finally, dark roast beans have lower acidity, if that matters to you. Enjoy!
