Just our two cents worth but we insist on using Chinola (we have tried Passoa...once). Reading the fine print on labels and doing a bit of online research (for example about real fruit content) usually makes the choice clear. Cheers.
Totally agree with you there. I have both in my cabinet, chinola you can't beat but there has been the odd cocktail that really suited passoa. Have had a lot of fun making the same ones side by side :)
