Olive oil tasting glasses

Olive oil tasting glasses designed to assess aroma, flavor, and texture of extra virgin olive oil.

About this subject

Olive oil tasting glasses are standardized by the International Olive Council (IOC) for professional sensory evaluation. They feature a narrow tulip shape, typically in opaque blue glass, which masks the oil's color to prevent bias. The design includes a wide bowl warmed by hand, a rim that concentrates aromas, and a stem to avoid heat transfer. The tasting protocol involves warming the glass, swirling to release volatiles, covering the opening, tilting, and slurping the oil.

The blue or amber color is critical because extra virgin olive oils have green and yellow hues that can affect perception. In international competitions like Italy's Oliocoppa Prize, each taster uses up to 12 glasses per session. Artisanal production occurs in regions such as Murano, Italy, and the most common model is the IOC glass with 15 ml capacity.

These glasses are also used in gastronomic fairs and workshops where consumers learn to differentiate monovarietal oils. A curiosity: the ideal tasting temperature is 20-25°C, and glasses should never be washed with detergent to avoid residue.

Frequently Asked Questions

What is the difference between an olive oil tasting glass and a regular glass?

The tasting glass has a tulip shape, opaque color (blue or amber) to hide the oil's color, and a narrow rim that concentrates aromas. A regular glass lacks these features and can bias sensory evaluation.

How to properly use an olive oil tasting glass?

Hold the glass by the stem to avoid warming the bowl. Warm the bowl with your palm, swirl the oil for about 30 seconds, cover the opening with your hand, tilt the glass and slurp the oil to spread it across your tongue.

Where can I buy olive oil tasting glasses?

Specialty gourmet stores, online marketplaces like Amazon, and olive oil producer associations sell IOC-standard blue glasses. They are also available in tasting kits for home use.
