I'm getting a creamy choc hit with a nice hint of mint, not overpowering mint, although I can't say what sort of choc but its moorish, had to up the ratio of the concentrate to 25 percent cause to be honest it's pretty cheap concentrate I got, you gotta start somewhere and it worked out for me.
I used this as a learning curve to get the percentage right.
And to see if I could do it, no point spending money on premium concentrates if you don't have the confidence to have a go.
Yeah, I'm well chuffed
