Coffee begins with espresso – an understandable and, at the same time, intricate liquid, on which the taste of several drinks and cocktails depends. The better you prepare it, the more aromatic and attractive the products based on it will be. High-quality coffee beans and proper tempering account for 75% success, allowing you to get the most of further processing. Bottomless coffee portafilter, in this case, is your primary weapon that will help to preserve all the properties of coffee in the cup.

Bottomless Portafilter vs Regular

The regular portafilter bottom has a double metal base with spouts from which coffee flows into the cup through a metal funnel. Bottomless portafilters without baskets are metal rings, so the espresso channel through the puck does not collide with additional obstacles and goes straight into the cup. An unobstructed view of the fluid flow is the main advantage of choosing this accessory, allowing you to trace the entire water flow cycle. In this way, you can improve your espresso technique.

Moreover, the bottomless naked portafilter allows you to get a more vivid taste, colour, and aroma of your espresso, thanks to the more coffee you can pour into it. Bottomless portafilters provide a syrup-like liquid texture and more crema, retaining more coffee puck substances.

Are Bottomless Portafilters Better?

A bottomless portafilter is an innovation that helps to create coffee masterpieces. The pinnacle of excellence in espresso techniques is a drink that not only looks good but tastes perfect as well. Correct grind, ideal dosage, excellent tempering, coffee beans' roasting, water pressure, and temperature help create a high-quality working material for bottomless portafilters. 

The magic of the naked bottomless portafilter comes as water passes through the puck, turning into a smooth coffee. The espresso is channelling into a single stream and flows into the cup, forming "tiger stripes" at the bottom of the holder. Using a regular portafilter does not allow you to trace these nuances. In turn, the bottomless holder demonstrates the creamy and firmness of the espresso. So it is not only a significant accessory for training and testing baristas but also a great way to enjoy the sight of a new coffee.

How to Use Bottomless Portafilters?

If you think that the bottomless portafilter will be more challenging in use, it is the right time to change your mind as utilising the naked holder is no different from regular. While many beginners are confused by the abundance of nuances of espresso colour and texture, gaining a valuable skill comes with experience. We encourage checking out thematic coffee blog articles where experts go into the extraction and channelling processes in detail and offer helpful advice on how to improve barista’s technique. For example, espresso bottomless portafilter for Gaggia Classic is an indispensable skill-building tool. Although the lack of spouts makes it possible to make only one coffee cup, cleaning the naked portafilter is much easier than the regular one.

Why a Bottomless Portafilters?

1. Espresso Extraction TroubleshootingTrouble Shooting. Bottomless naked coffee portafilters allow the barista to deduce if a proper tamping technique has been used instantly. If the pour is only coming out of one spout, an improper angle was used when tamping, the incorrect amount of coffee, or it was tamped unevenly.

2. Consistency. With the ability to troubleshoot espresso shots gives you that much-needed edge over the competition.

3. Crema. In the hands of an experienced barista with fresh espresso beans, a bottomless portafilter will yield 50% or more of Crema. Why? Well, the answer is simple. Your espresso shot will come in contact with no other surface than the bottom of you portafilter basket - no portafilter bottoms and no spouts. This keeps the tiny Crema bubbles we all look for in a perfect shot intact and unharmed. Furthermore, the lack of a spout will give the user more cup clearance and allows espresso extraction directly into the cup for serving in most cases. Of course, in most cases for to-go cups larger than 12oz, brew vessels of some kind will still need to be used.

4. Taste. More Crema means more flavour. As it is easier to clean, there will be less contamination from dirty spouts and a dirty portafilter. And if there is a build-up of coffee oils on the bottom of the portafilter basket - it can easily be spotted and cleaned.

5. Training. For all the reasons above, naked portafilters have become a valuable tool for espresso training. Novice Barista and pros alike can now instantly and visibly determine if the grind, dosing and/or technique is on or off. 

Troubleshooting Naked Portafilters
Problem: Coffee spray - when extracting, coffee sprays all over.
This makes an unholy mess.
Solution: Best cured with even tamping - make sure when tamping that the tamper is at 90-degree angle to the filter basket and correct and even pressure is applied to the tamping. Tampers with 58.5mm are ideal for this as they prevent uneven tamping. Low grind may also be the cause of spray, so make sure that grind is fine. 

Problem: Channelling. Water runs too quickly through some parts of the puck and will struggle to run through others. And this can result in spray or coffee running down the portafilter handle.
Solution: Make sure tamping was at 90-degree angle to the filter basket.
Adjust grind to make it more delicate and check time as it should take approximately 18-23 sec for 14g to fill 60ml. In case of coming out fast, consider altering the grind.

Problem: Lack of coffee cream 
Solution: Grind may not be fine enough; not enough coffee in the portafilter basket or tamp pressure was too light. Usually, it is a combination of grind and quantity of coffee.
