As mentioned elsewhere, the only “open format” for one cup coffee makers is the coffee pod.
Anyone can make coffee pods and sell them for use in pod brewers.
Then there is Keurig’s approach to single serve coffee with their proprietary K-Cups. K-Cups are not an open format. You need permission and a license to put your coffee in a K-Cup.
This latter “closed format” scenario is also true of Tassimo’s T-Disc.
The T-Disc is the third and, so far, final format for one cup coffee makers.
You can only use the T-Disc in a Tassimo brewer. And the Tassio brewer can only use T-Discs.
We’ll go into more detail about the Tassimo machine itself on our review page.
But there are some marked differences between a T-Disc and a K-Cup.
For instance, when you buy T-Discs to make cappuccino, which isn’t an option with K-Cups anyway, you receive a package with separate groups of discs, some containing the ground coffee, and the others containing the milk.
This gives the Tassimo system a wonderful flexibility and allows it to offer not only coffee, but also latte, cappuccino and hot chocolate with a frothy, milky topping.
But before you make the leap, keep in mind that you can buy coffee pods from a dozen or more roasters, you can buy K-Cups from three or four roasters...but you can by T-Discs ONLY from Tassimo.
In other words, before you pick the one cup brewer, give some thought to the coffees you are going to want to brew, how much choice is available...and where you are going to buy them.
