Volcano Espresso Shot Glass 100ml – Stainless Steel with Measurement Scale

Measuring espresso accurately is the difference between dialing in a recipe and guessing at one. The Volcano Espresso Shot Glass is a 100ml stainless steel measuring cup designed for precise espresso output measurement — with a clear visual scale, a Volcano-profile shape for easy pouring, and the durability of food-grade stainless that will outlast plastic alternatives by decades.

Why Measure Your Espresso Output?

Espresso recipes are defined by three numbers: dose in (grams), yield out (grams or ml), and time (seconds). Most home baristas track dose and time — but measuring yield closes the loop. A 1:2 ratio (18g in → 36g out) is a common starting point, but your machine, grind, and beans may dial in better at 1:1.5 or 1:2.5. Without measuring output, you're optimizing by taste alone — which works, but takes longer and produces less reproducible results.

The Volcano Shot Glass makes yield measurement visual and instant — no need to pour into a separate scale cup. Measure directly in the glass, note the ml line, and adjust your recipe accordingly.

Key Features

Volcano Design Profile

The wider-base, tapered-neck Volcano shape serves two purposes: it creates a stable base that resists tipping under the portafilter spout, and the tapered neck concentrates the espresso stream for accurate pour and visual inspection of the shot color and crema.

Measurement Scale

Clear markings at 10ml increments allow precise yield reading without additional equipment. Track single shots (20–30ml), double shots (40–60ml), and ristrettos (15–25ml) with the same glass.

100ml Capacity

Sized for single and double espresso shots with room to spare. The 100ml capacity also handles lungo (80–100ml) measurements without overflow.

304 Stainless Steel

Food-grade stainless steel doesn't retain flavor, doesn't crack under temperature changes, and never clouds like glass can with hard water mineral deposits. The metal walls maintain shot temperature during your measurement window — important when you're comparing shot quality to a calibrated standard.

Seamless Interior

Smooth, seamless interior walls make complete cleaning simple — rinse thoroughly and the glass is ready for the next shot without coffee oil residue affecting flavor.

How to Use in Your Espresso Workflow

1. Place the Volcano Shot Glass under your portafilter spout
2. Start extraction and timer simultaneously
3. Stop extraction at your target time (usually 25–30 seconds)
4. Read yield on the measurement scale
5. Compare to target ratio — adjust grind coarser (for less extraction) or finer (for more) as needed
6. Transfer espresso to your cup or drink directly

Frequently Asked Questions

Can I use this as a regular drinking cup?

Yes. The 100ml stainless steel cup is perfectly suitable as an espresso drinking vessel. The metal walls provide some insulation to keep the shot warm during sipping.

Is the measurement scale engraved or printed?

The scale is etched/stamped into the steel — not printed — ensuring it won't fade, scratch off, or become illegible with regular use and washing.

Is this dishwasher safe?

Yes. 304 stainless steel is fully dishwasher safe. Hand washing is recommended to maintain the exterior finish long-term.
