first question : is your tequila 100% blue agave ... or not ?
Unless the bottle specifies 100% Blue Agave, it is most likely a Tequila mixto (because it requires only 51% Blue Agave to be classified as a Tequila).
which challenges ageing tequila do face?
Experiments are being made in Tequila ageing but climate is dry and hot in Mexico, so evaporation is a serious challenge.
No one want to loose so much of the precious liquid over the years, especially when the taste is not dramatically improved during the ageing process.
and if your tequila is 100% blue agave DO YOU KNOW WHICH ARE the EXACT categorIES ? !
