Mezcal, as well as tequila come from the the agave plant. The difference is that tequila can only come from blue agave, whereas mezcal can come from any agave plant. Agave are neither cacti or aloes. They are members of the family Asparagaceae. Cacti are members of the family Cactaceae, while aloes are of the family Asphodelaceae.
I found these examples of agave at the Royal Botanical Gardens in Burlington, Ontario. I was drawn to the shades of green the smoothness and jagged thorns on the leaves. It was interesting to move very close to them to capture the texture and lack of texture on the various leaves.
I used the Nikkor Z 24-120mm f/4 S mounted on the Nikon Z6. The Nikkor is an amazingly versatile lens. It has a wide focal length range covering wide angle to telephoto. And it also focuses remarkably close to 16″ resulting in a ratio of 1:2.4. It was an overcast day which acted as a giant softbox in the green house.
