The red blend 2015 Rioja Reserva is 80% Tempranillo with 12% Graciano, 6% Mazuelo and 2% Garnacha, a little more Graciano and Mazuelo, something logical in ripe and warm years like 2015. It's produced with grapes from a diversity of the 30 different plots within the estate, to represent the character of if. It fermented in stainless steel and matured in American oak barrels for 18 months. It's spicy and somewhat balsamic, with some dusty tannins. It's a ripe and powerful vintage that only suffers next to the 2016 I tasted next to it when there's a jump in precision and finesse. This is by far the largest volume produced at Murrieta, with almost one million bottles.
