Nice thread!
I have a couple of Pitanga's here in Europe that have fruited last year and are all flowering right now. I'll have varieties of five different seed sources to taste test in a month or so. I am in Northern Europe, so I grow these in an unheated greenhouse, where a selection of plants has no trouble handling the -5 Celsius in winter nights.
My best variety is from seeds I bought it from Vitor, a seed collector from Brazil that posted on this forum in 2015 and 2016
The first and second Pitanga I fruited were from these seeds and it was a new fruit to me. After having read everywhere about that strange Diesel or Turpentine flavor I was curious to try, but I couldn't figure out what everyone meant. The first year only one fruited and the cherries were small but delicious. They tasted a bit like Bell peppers to me, but then wiht a more fruity and sweet flavor. The second year the other fruited and it also had that same delicious flavor. Everyone I gave them too loved them, so I was a bit mystified about that aftertaste story.
The last year the first plant from a batch of seed of a supposed orange Pitanga started fruiting, so I tasted one and bingo! -a ll of a sudden I realized what everone meant by Diesel taste.
The plants that are flowering now and I still have to try this year:
a seedling from Miguel's Regina variety, that he selected in Portugal
a seedling from a 'mini' Pitanga, also from Vitor from Brazil
a seedling from Cassio's Black Pitanga, also from Brazil
a seedling from Casio's Big Red Pitanga, also from Brazil
(I have many pictures but it seems i'm unable to post them here.)
I'll take Brix measurements and measure the fruits as well. My best variety has very small fruits, but they have absolutely not even a hint of turpentine taste - they are rather the size of blueberries then cherries, and any bowl you put on the table finishes quickly. It is super productive, though.
That big leaf variety looks impressive!
