I've been using a repurposed plastic box next to my espresso machine as my go-to knock box, but recently wrote a guide on knock boxes. I'm curious if you can recommend any particular knock box? They all seem universally the same and universally expensive.

    Honestly, knock boxes are in my opinion only necessary in a commercial setting. At your house, just dump it straight in the trash or keep using your plastic box. That seems like a great alternative and does the job just as good. It seems a bit pretentious to buy a knock box for 5 espressi that people make at home a day...and I say that having probably 10 different brewing devices at home :).

Osaka, Shock-Absorbent Espresso Knock Box 4.7 Inch Barista Style Knockbox.

about $20 anywhere online


Absolutely. There are many good quality knockboxes. You can find many reviewed on sites like Coffeegeek or of course, Amazon.

Knockboxes are practical and make it a pleasure to make espresso. I bought mine based on good reviews and after using it a few months consider it a great purchase.

It's made out of a good grade of tough plastic and can be found around $20 online or even less. Rubber coated knock bar and a well thought out cutout on the front for ease of access. Available in red, black and a few other colours. The stainless model is closer to $50 but is elegant if you prefer stainless and would stand up to genuine commercial use.

I use a Cafelat Tubbi Knock Box in small because it's cheap and a nice size. If I was going to replace it I'd get a Rattleware Maple Knock Box because it's solid and beautifully constructed, plus it's quite handsome.
