Lab Report - 0008 – Blind Shaker Dosing Cup 1

Verdict

🔴 Rejected

This dosing cup looked promising on paper and performed well in a few areas, but one issue ultimately killed it for us: retention.

The shaker design does a good job of breaking up clumps. Unfortunately, coffee regularly remained stuck inside the cup after dosing.

That makes the workflow less consistent, exactly the problem this type of product is supposed to help solve.

What We Liked

• Well-built and nicely finished.
• Comfortable to use.
• The shaker design does help break up clumps.
• Easy to clean.
• No noticeable wear or loosening during testing.

Why We Rejected It

Retention.

The cup consistently held onto some coffee after dosing. Sometimes the retention was minimal, but other times a noticeable amount remained behind.

The problem became even more frustrating when preparing multiple coffees. You might get a clean transfer on one dose, then find coffee stuck inside the cup on the next.

For a product designed to improve dosing consistency, that's a dealbreaker.

Would We Recommend It?

No.

The shaker mechanism works, but the retention issue makes it difficult for us to recommend.

If the manufacturer can solve the static and retention problem in a future version, we'd be interested in testing it again. There's a good product hiding in here, it just isn't quite there yet.

Lab Notes

We were actually looking forward to this one. The concept makes sense, and we'd seen plenty of positive feedback about shaker-style dosing cups.

After using it for around 20 coffees, the shaker did what we expected: it helped break up clumps better than a standard dosing cup.

Unfortunately, it also introduced a new problem, coffee getting stuck in the cup.

And when we're testing coffee equipment, that's the sort of trade-off we don't like. If we're trying to improve consistency, introducing an unpredictable amount of coffee retention isn't exactly an upgrade.
