I brewed up this El Salvador Cerro Las Ranas this morning and I did notice a bit of wood in the brew so I can't place all the blame on the Kantan.
I mislaid my AeroPress and scale over the weekend packing for our camping trip, so I tried out the Kantan brewer today at work using my El Salvador Cerro Las Ranas Pulped Natural roast. I'm getting a strong cardboard / paper taste, I forgot to pre-rinse the filter, or the coffee has gone woody, but I suspect the former. Brewed with ~16 grams coffee and ~ 250 ml water.
In my mind the Kantan would be used in the case of when one is traveling and doesn't want to haul around a bunch of coffee gear. Where you have to assume the source of hot water will be a way off temp hot water tap on a airpot/commercial brewer. Which is similar to my office and where I tested it. All I got was cardboard, and really I would have rather just had a cup of the standard office swill. Yes, I eyeballed the amount of coffee and water so....
I like the idea and would think that maybe it would come in handy someday. But really if I'm going to be carrying around coffee (even pre ground in ziplocks
) I'll just carry around my aeropress too. Also like BlzrFan I don't like the amount of waste.
The Kalita wave though is a little rockstar of a brewer!
