Hario's stainless steel water kettle, the V60 Buono, has been spotted popping up in coffee houses and the kitchens of baristas for some time now. A detailed search on the web will reveal, for the moment at least, that the Buono seems to be widely accepted as the most useful pouring kettle available. What makes this kettle so popular amongst pour-over enthusiasts? Several reasons stand out.
First, the thin pouring spout enables greater pouring precision as well as a slower, more consistent and controlled rate of pour, both of which are very helpful in achieving a precise, prolonged extraction.
Second, the stainless steel construction and large 1 liter capacity contribute toward keeping up the brew temperature for the duration of the entire brew cycle.
Third, the ergonomics involved in the design of the kettle help to make using it much easier. This may not seem like much, but if you're brewing large batches of coffee and pouring for three or more minutes per batch, doing several batches of coffee will quickly become a chore if your kettle doesn't cooperate with you.
Combine all of these facets with the fact that the Buono is manufactured by Hario, a very popular name in the coffee-brewing community, and the kettle's popularity is easily understood. For best results, combine the Buono with a
V60 Dripper or
Chemex to get a truly exceptional cup of coffee.
Filtron
If I understand "cold coffee press correctly", I'm assuming this is similar to the Toddy or Filtron method. I've been using a Filtron (http://www.filtron.com/) with a good deal of success. The process is incredibly simple: poor water over coarsely ground beans, filter through a felt pad after ~ 24 hours of "brewing".
According to Toddy (http://en.wikipedia.org/wiki/Toddy_coffee), the absence of heat results in a 67% reduction in acidity.
One can pretty simply approximate the Toddy/Filtron method of brewing with any sort of container and a filter. It's about as simple as brewing gets. With the resurgence of simple, pour-over hot brewing, I expect to see cold brewing methods become more popular.
To my palate, cold brewed coffee is markedly smoother and less acidic than hot brewed coffee. With the acidity out of the way, a lot of the subtlety of the bean and the roast comes to the fore.
