AO 4 has been conceived by the winner of the I Biennial Prize of Monumental Art of the Otazu Foundation, the Chilean Alfredo Jaar (Santiago de Chile, 1956). His winning work, The Color of Our Lives ( 2015), consists of four cubes of water, glass, sound and light magically surprised in full dialogue between a 14th century dovecote and a 12th century Romanesque church. For this label, the artist has created a minimalist image, but with great depth: a drop of wine that seems momentarily suspended in the air, like a sun radiating light. This drop of light here symbolizes climate, temperature, movement, time and air, all essential factors that determine the quality of the wine. This drop of light is a microcosm of the world.
