I'm new to DIY and have only mixed up some Flavour Art single flavour mixes so far. I ordered some empty bottles from TW and a bottle of Gold Standard cherry concentrate. Looking at their website they seem to recommend 30% flavouring in the mix, this seems unusually high considering FA is around 5% (although I realise FA generally has a lower %age compared with most). Can anyone give an insight into what level mix they use as I don't want to waste flavouring on a wrong mix. I know personal preferences on mixes is variable but a ball park figure would be handy if anyone has used TW stuff.
