About Bottomless Portafiltas for espresso machines.

First of all Bottomless Portafiltas are similar to standard filter holders.The difference being there are no spouts attached. In addition there is no underside at all.

This small change makes a big difference. When it comes to making coffee, this tool changes everything.  Furthermore it’s coffee like you have never tasted before.

The first drip of the cone pour.

The coffee pours straight from the basket into the cup. Consequently resulting in coffee having less contact with solid objects. Therefore the coffee is extracted in a more direct and natural way.

Consequently this results in the temperature being maintained. Giving  a thicker and tastier Crema layer,

Crema is the result of oils from the coffee beans being heated up. Which is why it floats. In theory the more heat you have the better the Crema. Therefore the less disruption crema has on the journey, the thicker it comes out.

However it should be noted that if the water is too hot it will nuke the coffee resulting in less taste.

The central cone shape pour, achieved by tamping flat.

Build Quality.

Especially relevant between a good bottomless and a bad one, is the build quality.

Most of all there are some available that are ‘modified from standard’. These items have been crudely chopped horizontally.The chop leaves a nasty tatty sharp edge. This could prove to be very dangerous.

Baskets:

Bottomless portafilters come with a double 14G  or a treble 18G basket. The baskets are interchangeable. It is possible to use existing compatible single and double versions without any problems.

Height Advantage – Bottomless portafiltas:

Using bottomless Portafiltas allows more height to work with when making coffee. Another advantage gained by absence of spouts. There is more room left between the chassis and the machines group head.  Particularly useful if you want to use a taller or ‘takeaway cup’ to serve your drink into. The spanish call this Alto.

When the tamp is right the pour from the bottomless will resemble a cone shape. This is what what you should be aiming for.

A Great Barista Training Tool.

In order to get the best out of these you really do need to tamp straight. Failure to do this will result in channels of coffee shooting off in odd directions. For that reason it is now recognised as one of the best training tools for a barista available.

Don’t let that put you off , the benefits of use far outweigh the down side. The bottomless can be laid flat on a tamping mat. This is due to not having a spout connected to the base.

Using your arm with the elbow above and almost in-line with your wrist, allows you to easily tamp straight, imagine your arm and coffee tamper in unison acting as a piston and you’re half way there already.

Most noteworthy is it really does not take that long to master the technique and it’s like riding a bike, you will never forget how to do it and you will be pleased you took the time to learn something new and useful.

In conclusion

Hopefully that’s bottomless portafilters explained. Making coffee this way is pure, raw and unpretentious. If the real taste of coffee is what you’re after it doesn’t come any better than this. If western cowboys had drank espresso, this is how they would have made it.
