Blue tasting glasses are the tool of tasting panels: a small glass in opaque cobalt that follows the IOC/T.20/Doc. No 5 standard of the International Olive Council. This case brings six, which is what you need to set up a tasting table that makes sense.
The colour has a purpose. With blue tasting glasses nobody can be swayed by the green or the gold of the oil before smelling it: the glass hides it, and the verdict is left to aroma, bitterness and pepperiness. When the oil goes round, only what is smelt and tasted counts.
