Don Julio González founded his distillery in 1942 in Jalisco, and in 2006 he and his family planted what turned out to be their final agave field. That harvest was distilled, barrelled and set aside rather than released, and Última Reserva was built around it for the distillery's eightieth anniversary. The tequila is aged thirty-six months, placing it in the extra añejo category, and is held in a solera system — a fractional blending arrangement in which casks are never fully emptied, so tequilas of different characters are continually combined and the original harvest stays at the centre of the blend rather than being drawn down to nothing. The wood is used in two stages: a rest in oak that previously held bourbon, followed by a finish in casks seasoned with Madeira wine. It is made from 100% Blue Weber agave and bottled at 40% alc./vol.

Every bottle sold through Midnight Whiskey is sourced as an authentic, sealed product and inspected before it ships. Orders are packed with padded, glass-rated handling and require an adult signature (21+) on delivery; we do not ship to anyone unable to verify legal drinking age.

What is a solera aging system in tequila?

A solera is a fractional blending system borrowed from sherry: casks are never fully emptied, and what is drawn off is topped up with younger spirit, so every bottling contains a diminishing proportion of the oldest liquid. Don Julio uses one here to preserve a specific agave harvest rather than to hit an age. It means the tequila is a blend of different ages by design, and that the original parcel is stretched rather than spent.

Why is it called Don Julio Última Reserva?

Última Reserva means "final reserve", and it refers to the last agave field Don Julio González planted with his family, in 2006. That harvest was distilled, barrelled and set aside, and the solera system was built around it so it would not simply be bottled and gone. The name describes the source of the liquid rather than the age of it.

What casks is Don Julio Última Reserva aged in?

Two stages. It rests in oak that previously held bourbon, which is the standard route for aged tequila, and is then finished in casks seasoned with Madeira wine, which is not. Madeira is a fortified wine aged under heat, and the casks bring the dried-apricot and orange character the producer's notes describe, over the toasted oak and caramel from the bourbon wood.
