Bottomless Portafilter Vs Regular Portafilter


Last Updated on July 1, 2023 by Timothy Byron Smith

Filter holders play a crucial role in the espresso-making process. They determine the quality and characteristics of the final cup of coffee. Among the various types of filter holders, two main categories stand out: bottomless portafilters and regular portafilters. Each type has its own unique features and benefits, catering to different preferences and requirements.

In this article, we will compare bottomless portafilter vs regular portafilter, their advantages, and disadvantages, as well as their impact on the overall coffee brewing experience.

Bottomless Portafilter VS Regular: The difference?

Before we can get to the actual difference between them to know, it’s important to establish what a bottomless filter is in the first place. Does it not have a bottom or what are we looking at here? Only one way to know: scroll below!

Regular (Closed-Bottom) Portafilters

Regular portafilters, also known as closed-bottom portafilters, are the conventional filter holders commonly found in espresso machines. They feature a solid bottom on which the coffee powder rests during the brewing process.

One of the notable advantages of regular portafilters is their ability to withstand higher pressure during coffee extraction. This higher pressure results in a more forceful extraction, which often leads to a stronger and more robust flavor profile in the cup.

However, the increased pressure in regular portafilters can have some drawbacks. It can lead to higher moisture in the coffee, potentially resulting in a loss of flavor. The excess pressure can cause the water to pass through the coffee too quickly, preventing optimal flavor extraction.

Despite this potential drawback, regular portafilters are widely used and appreciated by coffee enthusiasts who prefer a bolder and more intense flavor experience.

Bottomless (Open-Bottom) Portafilters

Bottomless portafilters also referred to as open-bottom portafilters, have gained popularity among coffee professionals and enthusiasts for their unique design and benefits. Unlike regular portafilters, bottomless portafilters do not have a solid bottom. Instead, the coffee rests on a metal grid, allowing for a different extraction process.

The absence of a solid bottom in bottomless portafilters alters the pressure dynamics during coffee extraction. With less pressure being exerted, the flavor profile of the resulting espresso is often milder and more nuanced.

This lower-pressure extraction allows for a more delicate and aromatic cup of coffee, where the subtle notes and flavors can be appreciated with greater clarity.

However, using a bottomless portafilter requires careful attention to the pressure levels. Since there is no solid surface to support the coffee, excessively low pressure can result in under-extracted coffee with a weaker flavor.

Baristas using bottomless portafilters need to closely monitor and adjust their techniques to achieve optimal extraction and flavor balance.

Bottomless Portafilter VS Regular: Which is Better?

Our home baristas would suit better with a bottomless portafilter. Despite some mess, it is extremely easy to use and clean. Plus, you can easily pinpoint your mistakes with this portafilter and learn your way to the best shot of espresso!

However, for professional baristas, regular portafilters with spouts would be best. In a busy coffee shop, there is no time for splashes and countertop mess. Plus, a double-spouted portafilter would shorten the serving time by a lot!

Cleaning and Maintenance

Maintaining cleanliness is crucial for brewing consistently excellent coffee. In this regard, bottomless portafilters offer some advantages over regular portafilters. Cleaning a regular portafilter can be more challenging as it often requires unscrewing the spout and thoroughly cleaning all the nooks and crannies.

On the other hand, cleaning a bottomless portafilter is relatively convenient due to its smaller surface area. Flushing it with water after each use is usually sufficient to maintain cleanliness.

Moreover, the absence of a solid bottom in bottomless filter holders reduces the likelihood of bacteria and mold growth, resulting in a lower risk of coffee contamination. This feature adds an extra layer of hygiene and safety to the brewing process, making bottomless portafilters a favorable choice for those who prioritize cleanliness and sanitation.

However, it’s important to note that bottomless portafilters are more delicate than their regular counterparts. The metal grid on which the coffee rests can be damaged if not handled with care.

Any damage to the grid can potentially affect the quality of the coffee extraction, making it essential to handle and store bottomless portafilters with caution.

Cost and Quality

When considering the purchase of a filter holder, the cost can be a factor to consider. In general, bottomless portafilters tend to be more expensive than regular portafilters. The higher price is often justified by the perceived superior quality of coffee obtained with their use.

Many coffee professionals and enthusiasts believe that the unique brewing characteristics of bottomless portafilters result in a higher-quality extraction, making the additional cost worthwhile.

Ultimately, the choice between bottomless and regular portafilters comes down to personal preferences and the specific requirements of the coffee being brewed.

If you prefer a stronger and bolder flavor, a regular portafilter might be the right choice for you. On the other hand, if you appreciate a more delicate and nuanced flavor profile with pronounced aromas, a bottomless portafilter could be the better option.


Which portafilter is better for beginners: bottomless or regular?

The choice between bottomless and regular portafilters for beginners depends on personal preferences. Regular portafilters are generally more forgiving and easier to use, as they allow for higher-pressure extraction and produce a stronger flavor. Bottomless portafilters require more attention to pressure levels and technique but can offer a more nuanced flavor experience. It’s recommended to start with a regular portafilter and then explore bottomless options as you gain more experience and confidence.

Can I use the same coffee grind size for both bottomless and regular portafilters?

The coffee grind size can be adjusted for both bottomless and regular portafilters based on your desired flavor extraction. However, it’s worth noting that bottomless portafilters are often more sensitive to grind size variations due to the lower pressure during extraction. It may require some experimentation to find the ideal grind size that produces the desired flavor profile with a bottomless portafilter.

Do bottomless portafilters produce more crema compared to regular portafilters?

While some baristas claim that bottomless portafilters yield a thicker crema with a richer taste, the presence and quality of crema are influenced by various factors, including coffee freshness, bean quality, and brewing technique. Both bottomless and regular portafilters have the potential to produce excellent crema. With proper technique and attention to extraction variables, you can achieve optimal crema with either type of portafilter.

Summing Up!

Filter holders play a vital role in the espresso-making process, and the choice between bottomless portafilter vs regular portafilter can significantly impact the final coffee flavor.

Regular portafilters offer the advantage of higher-pressure extraction, resulting in a stronger and more robust cup of coffee. On the other hand, bottomless portafilters provide a milder flavor with intense aromas, requiring close attention to pressure levels during extraction.

When it comes to cleaning and maintenance, bottomless portafilters are generally easier to clean due to their design, reducing the risk of coffee contamination. However, they require more delicate handling to avoid damaging the metal grid. The cost of bottomless portafilters is often higher, but many coffee enthusiasts believe that the superior quality of coffee justifies the expense.

In the end, the choice between bottomless and regular portafilters depends on individual preferences and the desired flavor profile. Experimentation and exploration of both options can lead to a deeper understanding of the brewing process and help you discover the perfect cup of coffee that suits your taste.
