My first Mexican whiskey, (yes, with an "e") is this 53040, which was a lovely present from their distillers, who sent this incredibly looking bottle to me, in order to write an honest critic for it. The first you need to know is that the decanter is plain wonderful. It is a small oil can, which happens to be fully ecological. After talking to the distillery owner, he told me that the name "53040" was the zipcode of his hometown when he was a kid. 53040 is made out of four types of corn. Black, yellow, white and red, all from the Oaxaca zone in Mexico. Bottled at 43%abv, a copper color.  It was matured in french oak, american oak and sherry casks. Pretty complex stuff. On the nose, starts with "old" notes and then it changes into a very sweet aroma. Old books, mountainside aroma, sawdust, dehydrated oranges and coffee. Vanilla and chocolate. Humidity. Marshmallows, chocolate topping of the ice cream. Coffee with milk. Very appealing. On the palate, some crazy new notes that i haven't experienced in any other whiskey before. Tree tomato juice. Grapefruit juice. Gooseberries and vanilla. On the second sip i got a white chocolate note and again this tree tomato juice flavor. It has a nice power to it. Aftertaste follows the same path, giving me the same grapefruit juice, the tree tomato juice and some salty and sulphuric notes. Overall, this was an exciting dram, to say the least. First of all, it doesn't have the creaminess of other grain whiskies; and it has the complexity and level of a good single malt. It is actually oily and not creamy, something that would have made me guess this was indeed a single malt and not a single grain if i had this at a blind tasting. Some of the flavor notes are so crazy for me, like the tree tomato one, and that is enough to earn a good score, specially if the whiskey is very good as this one is. My score for it is 89 over 100.
