Altaïr is the name of a star which comes from Arabic meaning bird. It comes from Arabic Al Nasr al Tair “the Flying Eagle”. Altaïr (α Aquilae, α Aql) is the brightest star in the constellation Aquila and the twelfth brightest star in the night sky. It is currently in the G-cloud. Altaïr is an A-type main sequence star with an apparent visual magnitude of 0.77 and is one of the vertices of the Summer Triangle (the other two vertices are marked by Deneb and Vega). It is 16.7 light-years (5.13 parsecs) from Earth and is one of the closest stars visible to the naked eye. Altaïr rotates rapidly, with a velocity at the equator of approximately 286 km/s. A study with the Palomar Testbed Interferometer revealed that Altaïr is not spherical, but is flattened at the poles due to its high rate of rotation. Other interferometric studies with multiple telescopes, operating in the infrared, have imaged and confirmed this phenomenon.

Sideral is a Spanish word which means sidereal in English which means related to the stars or the name of the year for which there is a leap year every four years. The philosophy of Sideral is based on constant movement and creativity. It is unbridled passion, infinite yearning. Sideral has a capricious style with a playful nature: succulent, balanced, fruity, aromatic, and fresh. Here the winemaker Ana María Cumsille exercises more creative freedom.
