Just ordered the full 18 ones that available in Australia as they were discounted as a collection, anyone else tried these? If so do you mix at the suggested 15-20% or have you found your own sweet spot?
This is a must IMO.
Perhaps from here? https://www.flavourworld.com.au/one-shot-gremlin-concentrates/ I noticed a few have buyer reviews with suggestions at lower %s and even one where the vendor added that to the general description. There are a few listed in the elr database but if ya search other vendors reviews you might find more suggestions at least for a good place to start testing. Gl to u!
