- How much do these cups hold?
- Each cup holds 4 oz, about a single espresso or a small cortado. Two cups come in the pack.
- Can I put them in the microwave?
- No. Stainless steel must not go in a microwave. Heat or cool the drink first, then pour it in.
- Do they stack well for travel?
- Yes. The two cups nest inside each other, so they take about the space of one cup in a bag or cupboard.
- Are they good for hot coffee?
- They work, but the steel rim and body get hot with very hot drinks and there are no handles. Let the drink cool slightly or hold the cup with a cloth.
- Will they fit under an espresso machine?
- At 4 oz they are short, so most machines with a removable drip tray can fit them. Check the clearance under your portafilter first.
- Do they change the taste of the drink?
- Plain stainless steel is fine for coffee and water. Highly acidic drinks like citrus or tomato juice can pick up a slight metallic taste if left sitting.
