Essential Coffee Bottomless Handle: Along with a double shot espresso filter basket 14g volume. Kafvalubre bottomless portafilter has become a valuable tool for espresso training. Novice Barista and pros alike can now instantly and visibly determine without a doubt whether or not their grind, dosing and/or technique is on or off. Valuable clues tell an informed trainee where work may be needed. Espresso Extraction Troubleshooting: Casabrews portafilter allows barista to instantly deduce whether proper tamping technique has been achieved. If the extraction leans to one side or the other an improper angle was used when tamping. If rogue streams of espresso are seen coming from the bottom of the basket it is possible that your espresso portafilter was leveled and or dosed unevenly. Better Crema and Taste: In the hands of an experienced barista with fresh espresso beans, a bottomless portafilter will yield 50% or more of Crema. Why? Your espresso shot will come in contact with no other surface than the bottom of you coffee portafilter basket. No portafilter bottom and no spout. This keeps the tiny Crema bubbles we all look for in a perfect shot intact and unharmed. Furthermore the lack of a spout allows espresso directly into the cup for serving in most cases. Double Shot Portafilter Baskets: The usual standard for commercial and prosumer machines, double shot filter baskets can often hold 14grams of ground coffee. This is probably what you want to use on most days. Detachable double cup coffee basket is easy to deep clean inside 51mm stainless steel naked portafilter. Food grade and dishwasher safe non pressurized basket along with it. As a training tool the bottomless portafilter is excellent for checking your tamping technique. Increase crema, better mouthfeel and it's just tastier.

Kafvalubre coffee bottomless portafilter allow you to see the espresso as it exits the basket. This allows you to immediately identify any faults in your dosing or tamping skill. You may be tamping slightly unevenly without releasing it. with a 51mm bottomless portafilter you will see espresso leaving one side of the basket before other side instead of it appearing evenly, something which would be impossible to gauge with a spouted portafilter.

What is channeling?
When you tamp your well-dosed grounds evenly inside the portafilter you will force the water to seep uniformly through the puck, resulting in a balanced extraction.
But if you rush the tamping process, your puck will have varying levels of compactness and resistance. This is bad because water will only pass through the areas, or channels, that have the least resistance. If this happens, you will be left with a chaotic cup that has both under extracted and over extracted tones.

A bottomless portafilter can prove very useful in identifying channeling

You can evaluate the number of channels, their direction, oreentation and speed, etc. Then you can use this data to reflect on your process. For instance, a large number of channels over the peripheries suggest that your tamper doesn't exert enough pressure in that area.

With enough time you will have a detailed plan for making the perfect espresso possible.

51mm bottomless portafilter, a perfect tool to improve your barista skill.

As the shot pulls you can see the droplets of espresso forming on the bottom of the basket. You can then see the stream flowing down into your cup. it's incredible.
Be your own Barista.
