Hi @jikrul80
When I was a child, I used to eat this fruit frequently, because there were many trees of it near my school. I rarely drank the juice made with it, but I know that its flavor is wonderful when it is very ripe, which is when it is very black. I'm sure the juice you made was delicious, I've never drunk it accompanied by leaf mint or lemon soda, but it must be a very interesting flavor.
In my country, this fruit is known as "beach grape" because it grows near beaches. Its scientific name is Syzygium cumini, it would be great if you edited and put that name in your post.
One observation I will make regarding your post is that you try to post sharper photos, not blurry ones, as there are some that are blurry. I also recommend that you take photos during the day, since indirect natural light (for example, that which comes through a window or door) favors taking photos of drinks and food.
Cheers!
Thank you @sirenahippie to point out my mistake to take clear photo. Next time i will take clear photo. And i,m edit the name of fruit. In our country this fruit called jam.
