I received a free sample of blood orange and the mixing percentage was in the product description on the website. If there isn't one I'd try 5 or 10% and make adjustments from there.
Thank you guys for the information. I did notice the suggested usage on the Chefs Flavours product description. The issue I have is I used 15% for Absinthe and the flavour was very mild. However.. just 10% of the Skittles concentrate created lots of flavour which I was happy with. Should I go over the 15%?
Well suggested usage is precisely that...a suggestion. Use whatever percentage gets you the flavour you like, unless it's one of those juice types that can mess up your tank at high %'s then I guess anything goes.
