Among Casta's original products, Casta Oro is 100% Blue Agave Tequila. Aged in white oak casks, it contains a percentage of Casta Weber Azul (tequila aņejo) adding strength and vitality to its nature. Full bodied. Big brawny flavor that covers your palate. Enjoy it! Each bottle is made from hand blown glass and thus is a unique, collectable piece of art that is also hand numbered and signed. One bottle requires twelve of our most experienced craftsman and twenty minutes of skilled artistic work to produce. Afterwards each piece is tested to validate the correct liquid volume.
