By comparison the Oxo Cold Brew is much easier to use since you can dump all your grounds in at the same time. The Oxo also has a handy "rainmaker" lid you pour water over which acts as a shower head for even saturation and coffee extraction.
The Filtron, another cold brew product, also takes all your grounds in one go but uses a third part -- a water bowl -- which adds extra complexity and size. The Toddy isn't small either and its tall height requires lots of overhead clearance.
After 12 to 24 hours you remove the rubber stopper to drain your fresh cold brew liquid into the decanter, about a 20-minute wait. Your patience will be rewarded with a flask full of almost 36 ounces of concentrated coffee. This is about as much java as the Filtron brews but half of what you get from the Oxo Cold Brew. My drink was strong too, with a high TDS (Total Dissolved Solids) percentage of 4.7 percent.
All this makes the $40 Toddy system quite compelling to people serious about their cold brew. If you don't mind less coffee per run and would rather use a metal filter, the $50 (roughly £40, AU$65) Oxo Cold Brew is the better choice.
