Your list has some of the best berry flavors: Bordeaux, Dark, Adriatic as well as some unique flavors but you’re missing the figs in the intense Sugar and Honey categories. These are Celeste (Improved), Hollier, Barada and Qalaat Al Maadiq. Children have a higher metabolism and like sweeter fruit, where as older people have a slower metabolism and like fruit that is not quite as sweet but has more uniqueness and complexity. Other factors to consider besides fruit flavor and sweetness are richness, juiciness, and figgyness flavors. You’ve probable read this already: Fig Flavor Categories, and taste scale...
Of course, it’s been posted a million times that tastes are completely subjective and fig flavor will vary a lot depending on too many things to mention. Until you grow them and taste them yourself, picking each fig at their peak degree of ripeness, speculation is almost meaningless. HOWEVER…it’s fun to speculate anyway.
The more people you can appeal to, the better are your chances of success, since different people like different things. Getting them to accept new fruit tastes and textures will involve teaching/marketing over time and a resulting slow learning curve. You will have to do a lot of advertising and give taste testing sessions to sell your figs to a negative biased public, but it has a lot of potential if you’re patient and resilient. Here I’ve seen local people promote heirloom tomatoes over the last twenty years until finally it’s beginning to be a viable market. Heirloom tomatoes simply taste better and sell themselves once people’s taste buds are educated and they have the disposable income to buy them. This has worked with the wine market as well.
Most people “eat” with their eyes at first and don’t notice the taste. Colorful figs like Panache, or bright colored red (Lebanese Red) or large yellow fruit (LSU Gold) would be more popular with them. Most of the commercial studies of fig marketability like Condit and the Hawaii studies focus on this element and limit the studies to easily available varieties with thick skins for shipping. They’re of limited value if you want exquisite flavor with your figs that will give them a meaningful edge over the other fruit in the market. http://www.hawaiifruit.net/index-figs.html
Some people find the seedy texture of figs distasteful. Seedless “jelly” figs like Mary Lane Seedless might appeal to them, at least at first until they begin to accept the flavor seed crunch can add to a fig’s taste.
Some of the trees you’ve chosen are “prima donna” varieties that are hard to grow and are not very productive, like Black Madiera. Grafting them on vigorous rootstock perhaps has the potential for improved growth and production. How good are you at grafting figs?
Best of luck with your project. With the changing global environment and scarcity of water, figs would be a great “green” alternative to the more conventional fruits in the grocery store or farmer’s market. It’s wonderful to see more figs available -even if they cost $10 a basket. But the flavor had better pack a competitive punch, or people will stop buying them.
