However, French Press coffee makers have
three major drawbacks: 1) Because grinds remain in the
bottom of the press, they continue to brew as long as coffee
remains, causing a bitterness from what is called "over
extraction"; 2) They are a mess to clean, and the process
contributes to breakage of the glass; and 3) There is a
considerable amount of coffee sediment that ends up in your
cup using this brewing process.
The
Tirra coffee maker is actually a French Pull,
as Ground coffee is placed on top of the
cup-shaped plunger, which you start in the bottom of the
pot. Hot water is poured over the grinds, which are
pulled out when finished. And once you get the hang of using this "pull"
style coffee maker, it addresses all three of the major
drawbacks of traditional French Presses.
Since
grinds are pulled, and then locked in the cap, there is no
problem of over extraction, and clean up is a breeze. We
also noticed a pronounced reduction in the amount of coffee
sediment, probably because you are not pouring coffee with
all the grinds pressed in the bottom of the pot.
We did two tests. At Morning Star Coffee, we
used hot water from the tap of a commercial brewer, which
entered the Tirra at 192° F, and after a
brew time of just under 5 minutes, serving temperature was
an almost perfect 175° F. After getting the grind coarseness
right on our second try, we enjoyed a truly incredible cup
of rich coffee.
The second test was conducted
using boiling
water, as you would likely prepare your coffee at home. Water was poured in the Tirra at just under 212° F, and after the same brew time,
serving temperature was 190° F. Again, great results. After
brewing the coffee, since glass loses heat rather quickly,
we suggest pouring any extra coffee in a thermal container.

The 32 oz. (1 L) and 16 oz. (.5
L) Tirra coffee maker's
suggested retail prices are $29.99 and $24.99 respectively.
