Advantage of Using Bottomless Porta Filter

Advantage of Using Bottomless Porta Filter

Greetings to all dear baristas who’ve been thoroughly looking for useful guidance on using bottomless portafilter to improve espresso technique.

The china coffee machine portafilters help you put better shots and puts an extraction in full view, so you can evaluate it and make adjustments to things like tamping technique, and a whole lot more, and well those naked extractions.

What does a bottomless portafilter do? Why it is beneficial?

Well, both the spotted and bottomless portafilter start the same way, the difference comes in a process that is covered up. You can see espresso is finding its way through tiny basket holes, and as it all comes out and starts to cling together, it starts to form distinct streams.

On other hand, if espresso is coming out evenly as is the goal, you’ll see the streams quickly become one; so beyond just being able to see the streams come out, there are a few other considerations when it comes to using bottomless portafilter;

Firstly, the espresso will have less contact with the portafilter, and that means less contact with the metal. Some might argue that metal itself could potentially impart off-flavors, but I think is a real argument is that internal components of portafilter can get very dirty with coffee oils, and sediment over time. If they aren’t being cleaned on regular basis, then every new shot of espresso would be dragged over this old stale coffee kind of gross.

So, by using a bottomless portafilter, there’s no need to worry at all about cleaning the inside of the portafilter, and you can quickly turn over the bottomless basket and check when it needs to be rinsed. It’s a little bit less cleaning and just a blast of water will do the trick.

When you’re in ab busy café and in the meantime, you little more assurance that your espresso is consistently tasting fresh and new.

Second, A bottomless portafilter is a great training tool. If you tamp down unevenly, it is very easy to see that you’ve done something wrong with the bottomless portafilter. If one side starts dripping sooner than the other, or if streams of coffee are very off-centered, then it tells you that certain areas of your puck got wet; first saturated quicker, and ultimately extracted differently than other areas of your puck.


Even for experienced baristas, this is a great test to see how well you tamp, but it also helps with other aspects of espresso preparation – most importantly, how well you’re distributing the grounds inside the basket. If you see the espresso starting on the outsides, and converging towards the center, this means you have a higher density of coffee grounds.

In the center of your puck, if you’ve distributed the grounds evenly i8nto a clean dry basket, the espresso should come out evenly across the entire basket. Now the shot you’ll see would be far better than the previous one. With a bottomless portafilter, you’re able to identify the problem.

What Else to consider? Sizes of Portafilter Basket

Single Shot Baskets — The short bins normally hold 8-10 grams of espresso. It further includes a more modest arrangement of openings at the lower part of the container to lessen stream speed.

Twofold Shot Baskets — The ordinary norm for prosumer and business machines, twofold shot bins take around 16-22 grams of ground espresso. This what ordinarily individuals need on normal days

Triple Shot Baskets — If you need more caffeine than conventional, fly in a triple shot canister that can fit 30-35g of coffee inside. That will be a major triple shot!

I recommend thinking about the twofold shot crate. Since you’re presumably going to pull a 1:2 shot (1g of coffee to 2g of water), that will end up offering you a possibility around 32-40g, which is standard for most strength bistros.
