Professional 1OZ Glass Measuring Cup for Espresso Making

If you’ve ever pulled a shot of espresso only to find your milk-to-espresso ratio off, or struggled to measure a consistent single ounce for your cappuccino, you’re not alone. Getting precise measurements—especially that critical 1OZ (30ml) mark—is essential for balanced drinks, but most home setups lack a dedicated tool.

The solution is a simple, professional-grade glass measuring cup marked for 1OZ (30ml), plus additional volume settings. Whether you're dosing espresso shots or steaming milk, this tool ensures accuracy and repeatability for better drinks every time.

What Is This Measuring Tool?

The Koonan brand professional glass measuring cup is designed for coffee professionals and home baristas who need precision. It holds a standard 1OZ (approximately 30ml) dose—critical for espresso-based drinks—and features four different scale markings. This lets you measure not just a single shot, but also other common volumes used when building drinks.

Why Precise Measurement Matters in Espresso Drinks

In the world of espresso and milk beverages, ratios define balance. A standard single espresso shot is around 1OZ (30ml), and most milk drinks—from cappuccinos to lattes—are built around that base. Without an accurate 1OZ measure, you risk inconsistent drinks: too much milk, not enough coffee, or vice versa. This is especially important when training staff or dialing in drinks at home or in a shop.

Key Features of the Koonan 1OZ Glass Measuring Cup

This glass measuring cup includes:

• Four graduated scale markings for different volume measurements
• A primary 1OZ (30ml) dose line for espresso shots
• Durable glass construction
• Available in both red and black color options

The clear markings allow for quick visual confirmation, reducing the guesswork when dosing espresso or pouring milk. Whether you're using a commercial machine or a home setup, having a dedicated 1OZ measure helps maintain consistency across all drinks.

How Baristas Use a 1OZ Measuring Cup

Professional baristas use the 1OZ measurement primarily for:

• Pulling single or double espresso shots where dose volume matters
• Building milk drinks starting with a precise espresso base
• Training new staff to understand drink structure and ratios
• Ensuring repeatability across shifts or locations

By starting with a known 1OZ shot, baristas can more easily control the balance of espresso to milk, leading to better-tasting drinks with the correct strength and mouthfeel.
