base threshold of quality, whether to choose an oil
that is buttery and rich or bright and grassy is
largelyuptoyou.
Oliveoilcomesinseveraldifferentgrades:
• “Virgin” and “Extra-Virgin” are standards set
bytheInternationalOliveOilCouncil,andthey
reflect a mark of quality. Virgin olive oils can
contain up to 2 percent oleic acid.Extra-virgin
oliveoilcontainsnomorethan0.8percentoleic
acid and it is subjectively deemed superior in
flavor to standard virgin olive oil. Neither of
these oils can be made from olives that have
been heated to extract oil. The extra-virgin
production of most countries accounts for
between 5 and 10 percent of their total output,
hencetherelativelyhighprice.
• “First Cold Press” indicates that the olive oil



was pressed from unheated olives and that the
oil came from their first pressing. To a large
degree,thislabeloverlapstheextra-virginlabel.
• “Pure”or“Light” has nothing to do with olive
oil’s calorie content—it is only an indication of
flavor. These olive oils are made from

have been heated to extract more oil.The oil is
then refined, so that none of the flavorful
compounds found in virginor extra-virgin oil
