DISK Review

January 20, 2011

I’ve been experimenting quite a bit this past couple weeks with Coava’s KONE, no sooner did I get back home to the states to get my hands and start the process of brewing with new equipment, than they released the DISK filter for the Aeropress, and no sooner than was I about to do a write up on both of these than they released another DISK with slightly smaller holes! (Not to mention the KONE funnel coming out in the next couple weeks)

Slow down with all the innovation!

Well, regardless, I’m getting around to reviewing the product now, and I’ve been more impressed with the DISK as a consistent brewing device. The Kone has gotten me to brew a different kind of coffee (read: oily, big bodied, slight soot) by tricking me with one of my favorite brewing devices, the Chemex (read: clean, crisp, bright brews). However, I didn’t own an Aeropress before I was given the DISK + Aeropress combo for Christmas, and so naturally i’ve been drawn to brewing with it often.

Here’s my brewing specs for the DISK: 12-14g depending on the roaster, Inverted Aeropress, 200ml water poured in 10seconds, snap lid on and flip over the sink at 60 seconds (some coffee falls out into the sink that mostly contains fines and soot), set on cup, at 120-150s remove plunger and let the coffee drip through, depending on grind size it should finish up around 180-210seconds. I grind around 22 on the Virtuoso Preciso for a starting point, This gives a really balanced cup that highlights the aromatics and sweetness with very little soot. I’ve not had any good results actually using the plunger to push the brew through the filter, every time it ends up horribly sooty with a terrible astringency.

The best part about this filter (and brewer) is the easy clean up, while the KONE takes a little bit longer to clean, the DISK is no hassle at all to rinse and get rid of the coffee grounds and oils. As well, at a lower price point of $15 for one, $25 for a set of two different sized filters, it’s a more affordable luxury.

All in all, I can’t recommend Coava’s products enough. Though many don’t have the means to purchase, they are at least helpful to get one thinking about brewing in a different way, and moving the coffee industry further past the need of paper filters.

Watch here tomorrow, I’ll be posting some thoughts about a brewing experiment i’ve been working on with the DISK…
