Coffee grinder for filter and espresso | 1Zpresso

Find the right level of precision

1Zpresso builds manual coffee grinders with roots in engineering expertise and a clear focus on Specialty coffee. This is especially evident in how the series is structured: the same basic idea of fast, clear grinding control with external adjustment, but different models for different brewing methods and different preferences in the cup.

The most important choice here is not appearance but usage. If you want to fine-tune espresso very precisely, there is a model built just for that. If you prefer clear separation and clarity in filter coffee, there is a clear specialist. And if you switch between several brewing methods, there are two all-round options where the difference mainly lies in how finely tuned you want the feel to be, how compact a format you seek, and which design you prefer for daily use.

Two clear specialists and For those who switch between brewing methods

J-Ultra & ZP6

Here meet the series’ most targeted choices: one for those chasing exact espresso settings, and one for those who prioritize purity and separation in the filter cup.

K-Ultra & X-Ultra

Both models work broadly, but they feel different in practice: one is the most versatile in the series, the other more compact and finely stepped for those who want to move between espresso and pour-over with smooth handling.

J-Ultra

For espresso focus

This is the choice for those who mainly brew espresso and want to work with very small steps between settings. It is especially suitable when you want to fine-tune the shot with high precision rather than switch between many brewing methods.

ZP6 Special

For clear filter cup

For those who brew pour-over and seek clear flavor separation, this is the series’ most refined filter choice. It is better suited for daily brewing where cup clarity and easy cleaning weigh more than espresso adaptation.

K-Ultra

Widest range of use

If you want a grinder that covers many brewing methods without feeling specialized in just one direction, this is the most versatile choice. It suits you who want one and the same model for espresso, filter, and other brewed coffee.

X-Ultra

Compact crossover

This model suits you who want to combine espresso and pour-over in a more convenient, more stripped-down format. A good choice when you appreciate a finer adjustment feel than a broad all-round model but don’t need a pure specialist.

Frequently Asked Questions

Answers to what most often determines the choice between models.

Which model should I choose for espresso?

If espresso is your main brewing method, J-Ultra is the most accurate choice in this series. It is clearly focused on very fine control, which makes it especially relevant when small adjustments noticeably affect extraction.

Which is best for filter coffee and pour-over?

ZP6 Special is the clearest choice for you who mainly brew pour-over. However, if you want to switch between filter and espresso without locking yourself into a single style, K-Ultra or X-Ultra are more flexible options.

What distinguishes K-Ultra from X-Ultra?

K-Ultra is the broadest all-round choice in the series and suits you who want to cover many brewing methods with a single grinder. X-Ultra is more compact in expression and targets you who mainly move between espresso and pour-over and want a more stripped-down everyday feel.

What does external adjustment mean in practice?

It means you change the grind size without having to open the grinder. For you who often change recipes or brewing methods, it makes the settings quicker to read and easier to repeat from brew to brew.
