Absolutely fantastic video. Wow those ropes look incredible. I would love to see the actual making of them. I've seen the making of small twists which are only a quarter kilo or at most a half kilo. Those ropes are much more like the factory ones turned out by Gawith but much much fatter.
It makes sense that cachaça would be aged I'm sure that each wood must impart some great character. I'm sure its a fascinating rabbit hole to explore. I've heard of a rum in Germany that is aged in black walnut grown in Afghanistan. I would love to get my hands on a bottle of that some day.
Cobs are great smokers and are surprisingly durable. I have a number of cobs that I smoke regularly that are 80 years old or more. Cobs are also great fun to modify to try things like reverse calabash with etc. If you have any trouble getting a cob I'm sure we can find a way to get some down there to you.
