Ok, I have an update for this.
It is toward the end of Week 6, and Tepoztecatl and Colhuatzincatl (a.k.a. "Tepoz" and "Col") just returned home from their trip to Champs Les Sims, France.
They each have mastered the Nectar-Making skill and have achieved the Flavorful Feet challenge with over 180 bottles of nectar made, each!
I ran out of life fruit on my second to last day, so the final batches of nectar were definitely below their capabilities, but every little bit helps!
I just hope I have enough time left to grow, harvest, squish, ferment and age my way to a respectable finish...
P.S.- With all the life fruit I'm growing in this challenge, I figured "what the heck" and have had both my sims eating it on a daily basis! Eternal youth is miiiiiiine!!!
