The nondescript, austere black bottle that is San Matias Gran Reserva Extra Añejo Tequila has been one of the bar industry’s best kept secrets for well over a decade.

Made at NOM 1106, the Tequila de San Matias distillery’s aged bargain has long been a Tequila touchstone to those in-the-know, no different than how many of us feel about In-N-Out burgers or Arizona iced tea: a dependable, no nonsense product of quality that hasn’t really gone up in price for as long as we can remember.

$50 for a dependable, butterscotch-laden Extra Añejo Tequila is already a great price as is. Today, however, we’re gonna knock an extra $10 off that deal and give you all that extra maturity for the same price as most blanco Tequilas these days.

You can read the reviews on the always dependable Tequila Matchmaker for both a fair overview of the product and a look at the standard MSRP. You’re likely to come to the same conclusion that we did years ago: while it may not blow you away, it’s a damn good product for a very fair price.

And that price just got even better today—for a limited time! Who’s ready for Tuesday night shots on a warm summer evening?
