What matters when choosing?
Start with a usable coarse setting for cold brew. Then choose the dosing and cleaning routine your colleagues can repeat, while treating workplace suitability as a check before the grinder is used.
| Concern | What to check | Who this matters to |
| Coarse grind control |
Look for a documented coarse or cold-brew-capable range; agree and record a starting setting. |
If I am preparing the same cold brew for colleagues, I need a grind setting we can return to after someone changes it. Around 36% of consumers put that grind consistency first. |
| Repeatable batch doses |
Check for a scale or weight programme and a container that suits the intended batch. |
When we prepare planned batches, I want colleagues to use the agreed coffee quantity rather than judge it by eye; roughly 29% of consumers make repeatable dosing their primary concern. |
| Cleaning and handover |
Check which containers can be removed and how the grounds path is cleaned. |
In a communal kitchen, I need the next person to find the grinder ready to use, without leftover grounds causing confusion. For around 21% of consumers, that shared workflow comes first. |
| Workplace suitability |
Confirm the relevant electrical supply or charging arrangement and ask about workplace approval and maintenance. |
Before we bring a grinder into the office, I need to know it can be used within our equipment rules. That is the first concern for roughly 14% of consumers. |

Common questions
What grind should we start with for office cold brew?
Start at medium-coarse to coarse, then adjust for your coffee, steep time and filter. Fellow Products uses that range in its cold-brew method, but its numbered settings should not be copied to a different grinder.
Should we choose a burr grinder rather than a blade grinder?
Choose a burr grinder if returning to a consistent cold-brew setting is a priority for your office. Fellow Products identifies a burr grinder as important to consistency in its method; also check that the particular grinder has a suitable coarse range.
Does an office grinder need annual PAT testing?
Not necessarily. The Health and Safety Executive says annual portable appliance testing is not required for every appliance in a low-risk office, while electrical equipment must be maintained so that it does not present danger. Follow the inspection and approval process that applies in your workplace.
What should we check before using a grinder at work?
Check that it suits its intended use and, where relevant, the electrical supply. The Health and Safety Executive also advises checking equipment condition, including the plug, cable and outer cover; ask your facilities or health-and-safety contact about workplace approval.
Can we use a grinder listed as 120V in a UK office?
Do not assume that a 120V listing identifies a suitable UK office appliance. The Fellow Ode Brew Grinder Gen 2 page referenced here specifies 120V, and the Health and Safety Executive advises that work equipment be suitable for its electrical supply. Check the exact variant’s voltage, plug and seller documentation before buying.
