Very interesting, Nacho.
There were some very interesting articles a couple of years ago about the agave fields in Mexico and Central America and how the men who have tended to them for decades are getting old and will not be able to work the fields much longer. And, there are not enough young people coming along who are interested in working that hard their whole lives, so replacements for these farmers are hard to find. I think it would be terrible if tequila production were affected because of this; hopefully they have found enough people to take over.
I'll haven't read anything about this lately, I'll try to see if I can find some of those articles I read.
