One of the key factors in determining a tequila's quality and
character is its level and type of aging. Tequilas commonly consumed
can range in age anywhere from one day to several years out of
the still. The following is a definition of aging terms.
Blanco
Tequila in its pure form is blanco or white tequila. It is also
referred to as "silver" or "plata". This tequila has not been
aged.
Reposado
Reposado translated literally means "rested." By law, a reposado
tequila must be aged in wood for at least sixty days. They are
almost always aged for less than one year. The aging in wooden
barrels changes the tequila from a clear liquid into a light straw
or even medium golden color. Reposados taste less harsh and slightly
more mellow than blancos.
A–ejo
A–ejo translated literally means "aged." By law, an a–ejo tequila
must be aged for a minimum of one year and it must be aged in
government-sealed barrels that are no larger than 600 liters.
Most a–ejos are aged anywhere between 1-3 years. The longer aging
period gives the a–ejo a darker appearance and a smooth, mellow
flavor reminiscent of bourbons and whiskies.
