LAGOM 01 Burr Basics 101.

A precision tool that lets you control particle size distribution down to the microns?? Why does that matter? In a nutshell, different burr geometries produce different particle curves (e.g. bimodal vs. unimodal for those that like to dive deep), which directly dictates whether your cup sings with clarity or punches with body. 🥊

We like to say grind size charts are the journey, but burr geometry is the destination. Whether you’re dialing in light roast for a low-fines brew or chasing high body vs. high clarity, your answer starts with particle distribution.

How do the three LAGOM 01 burr types grind and distribute coffee particles according to flavor profile?? Swipe ——————————>

THE BURRS:

⚙️ MIZEN: Balanced / Sweet
The all-terrain option. Produces a balanced particle size distribution with moderate fines for body + enough uniformity for clarity. Ideal for bouncing between espresso and pour-over. Exceptional with natural and processed coffees where you want sweetness without muting fermentation notes.
- TLDR: flexibility, balanced, sweet lingering finish.

⚙️ SSP HU: Bright / Floral / Robust
Aggressive flat burr geometry that leans toward a slightly wider distribution, more upfront flavor intensity. These deliver bright, punchy cups with excellent uniformity in the mid-range, accentuating the floral qualities at times, and shine with washed and cleaner coffees. Expect robust pour-overs and espressos where the first sip grabs you.
- TLDR: washed clean coffees, high-acidity, anyone chasing “clarity with guts.”

⚙️ SSP BREW: Clean / Low Body / Delicate
Ultra-high clarity burrs. These produce an extremely unimodal particle distribution, very few fines, almost no boulders. The result? A tea-like, translucent cup where intricate, nuanced flavors stretch out across your palate. Not for those who want body; essential for those who chase florals, bergamot, and stone fruit skins.
- TLDR: light, delicate complex coffees, filter-only obsessives.

WoC Bangkok - every LAGOM we saw in under 10 seconds. Swipe left, pinch, and zoom to see which grinder was spotted the most among the pros.

So much happened in just three days:

Proud to be the official grinder sponsor of the World Tasters Cup at Bangkok, watching the world’s sharpest palates give it their best. Kudos to every competitor who put in the work and earned the chance just to compete on this insanely high-level world stage. Congratulations!

It was also heart-warming to see so many LAGOM grinders in action (from Mini to 01), from booth pop-ups to Roaster Village, helping brewers and roasters serve delicious coffee all day. We did a quick zoom through the event for a little roll call, and snapped a few photos of them at work.

Thanks to everyone who popped by to visit us and check out our grinders at the booth. Great team, great people - if you’re in Thailand, please support them. They’ll take good care of you!

Next up: see you in Brussels in a month.

Bring your tongue. We’ll bring the grind.

Size matters.

Fits anywhere a card can (if it also fits in your wallet dm us 🤣🤣 we would actually love to see this). The 6.5cm footprint your apartment coffee setup, tiny coffee corner, or small kitchen needs.

“Does the PCS on the LAGOM 01 actually pre-crush? Or is it just… feeding?”

Fair question.

Also fair: we thought we showed/explained this already… but maybe not that clearly 😅

So here’s a quick (slightly scrappy - our editor’s on holiday version) video to clear things up.

Did the results surprise you, or was it what you expected?

LAGOM 01 users - how has your experience been, pre- and post-PCS? Let us know!

P.S. The necessary disclaimer: we removed a few parts for testing/demo purposes. This isn’t how the grinder is intended to be used - improper handling may cause damage.

P.P.S. PCS = Preliminary Crushing System. We coffee people do love our abbreviations 😅

Is it just us, or does cold brew always taste kind of the same?

There’s this familiar flavour - a signature taste we’ve come to think of as “cold brew flavour”. But… our minds might be changing.

Lately we’ve been using the Brezi in the Brew Lab to play around with cold brew (for those 30°C summer days hah), and it’s the first time cold brew has really made sense to us. Cleaner, crisper, without that signature “cold brew” note - more like the coffee we actually enjoy.

Brezi does something a little different - like a bit of a hybrid between traditional cold brew and flash brew. The coffee is bloomed with 55–65°C water, then extraction is completed with cold water. The result is a slightly concentrated brew that’s already chilled - ready to drink right away or poured over ice. Shoutout to for letting us experiment with this.

For the nerdy:
Dose: 15.8g
Yield: 193g
Brew time: 11 min (vs typical overnight)
Extraction: 19%
TDS: 1.5

Have you used one? Come by Brew Lab if you’re curious before it’s gone away.

For competition, and beyond.

We just released our official LAGOM 01 Competitors Guide to help World Brewers Cup competitors better understand and get the most out of the LAGOM 01 - and for all who brew with the LAGOM 01.

In the Resource Page, you’ll find workflow guidance, tips and tricks, technical notes, grinder care and maintenance tips, and other information related to the grinders, including the specifications.

This is one of the few ways we hope to support those brewing at the highest level-recognising the immense time, focus, and dedication every brewer puts into stepping onto the world stage.

For the full guide, visit option-o.com/wbrc-resource or via the WBrC tab in the top menu on our website.

Every piece of equipment benefits from a little care. When it comes to LAGOM grinders, we believe less is more.

There’s no need to clean it weekly (we know some of you do - and hey, you do you), but a yearly check can go a long way in keeping everything running smoothly for years to come.

When you do that yearly check, it’s worth giving a bit of extra attention to all the nooks and crannies. Here, we’re showing a complete (and relatively simple) deep clean of the chute, from start to finish.

It’s not something you need to do often, but adding this to your yearly maintenance routine can go a long way.

As always, start by unplugging your grinder for safety.

Check out the full guide on our YouTube, or save this for your next cleaning day.
