The precision-crafted 53-mm conical burr grinder is the highlight of the Varia VS4.
The special 6-core geometry ensures:

uniform particle sizes
excellent flavor clarity
higher sweetness in espresso

🌀 3. Single Dose – Minimal Retention for Maximum Freshness

One of the main reasons why the Varia VS4 is so popular: Retention close to 0 g.

ideal for light and complex roasts

Perfect for everyone who regularly switches between espresso and filter roasts.

This allows even the most demanding espresso recipes to be dialed in precisely.

That means:

perfect control over flow rate & extraction
reproducible results with every shot
ideal fine adjustment for pour over recipes

For everyone who likes to fine-tune their shots, this is a huge advantage.

⚡ 5. Brushless Motor & Planetary Gear – Power Meets Control

high, stable torque
low heat generation
smooth operation
consistent particle quality
