The PorcuPress is a new type of extraction tool. It is not a WDT tool or any kind of stirring prep tool. Ground coffee is a spread of particle sizes randomly arranged in a portafilter basket. When you pull a shot of espresso, water will always flow through paths of least resistance - which is not predictable. Because of this unpredictability, your coffee grounds are not extracted evenly.
The PorcuPress is here to help reduce channeling, specifically on very finely ground coffee. The tool perforates the coffee puck such that after you tamp, you will leave behind a defined array of less compacted regions. These regions will initially allow water through the entire depth of the puck. Water will then saturate outwards from each of these holes causing the entire puck of coffee to be fully wet. As the entire puck swells, these holes and other naturally present channels will seal up. Secondly, the PorcuPress will lead to a more even tamp as shown here which will further aid in extracting evenly.
The HD Offset Square pattern can be rotated 180º to press over 450 holes in just a few seconds!
Features:
Safety Lock
Depth gauge for convenient adjustment between different basket heights
Settable max plunging depth for repeatable use
Strong magnets!
Indicates off of portafilter lugs for repeatable multi-plunges
Lower buffer plate to keep grounds from lifting
Improvements over the previous PorcuPress:
Needle insert is machined from PPS plastic - a high-performance engineering thermoplastic that is gradually replacing metallic brew parts in espresso machines
Needle inserts are matched with a machined aluminum buffer plate to prevent grounds from lifting, protect the user and the needles from damage
Notices:
The PorcuPress is for standard 58mm baskets/portafilters
Non-black colors made in small quantities
B-Stock units have very minor cosmetic blemish(es) but are otherwise new and function like new
