Coffee from this system tends to taste rich and smooth. IMHO
Generally speaking, fairly easy to use.
Negative Product Points
Some would say the coffee lacks sharp characteristics they look for. It's not for everyone's tastes.
Available from a variety of online merchants and I've heard it's in stores, it's now fairly easy to find and purchase one, I paid about $30 for mine with decanter.
If you prefer mild, smooth coffees, this might be just the ticket for you. That doesn't mean cold brew will make good coffee from Folgers, or anything else fom a can. As an experiment I tried canned coffee (premium brand I won't name) in a cold brew, pretty disgusting in my opinion.
This isn't for someone who must get from ground coffee to coffee in the cup in 5 minutes or less. Some advance preparation is required. The litre (approx) of concentrate that results from a brew session does make each cup from concentrate quick to make, but the concentrate takes anywhere from overnight to a full 24hours. The time period is up to you.
