I was looking at your guide for nectar making and noticed that you had missed something that my Sims enjoyed. Fire Of Life has 5 perfect life and 5 perfect fire fruit. You get the Sugar Rush moodlet plus the warm fire moodlet plus great taste moodlet. That's usually why I make it for my Sims. I have two Sims that are topped out in the challenges and have Enhanced pressing and make extended nectoration. They typically get over 1000 per bottle when its well aged. I know the point is to make a profit so I don't always make that because its a loss on the raw fruit plus time. Simply put at 1000 I could do nothing more than sell the fruit and make money for the Sim but kept around it ages well and seems to help improve the other nectar. Both of my Sims are silly about how they stack the ageing rack. They want purple green and amber in each diamond or they have to put it in another rack. I have never found rhyme nor reason for the silly stacking but it seems to help. Gunther Goth is now starting to do it as well.
To wrap it up it is far more profitable if I have Pomelo/Lime plus Apple/Cherry plus Life/Fire plus any grape and any fruit mixed from 70/30 to 50/50 on my weird magic racks. I can never tell if the Watermelon Plum is going to make more or the Watermelon Pomegranate, but I wont sell any nectar for less than 600 and I once made more than 800 on a bottle of just lime nectar. I do stack the racks until I run out of room, and have 60 plus racks. They are the stacked ones and I fill 15 while the other 15 are ageing.
