Out of curiousity, what is the minimum amount you guys mix up per juice?
For me all testers are 30ml and the juices I like, are mixed at a minimum of 50ml and the ones I love, are mixed at 100 or 200ml at a time.
10ml testers were never a good gauge for me. I found alot of the time something would taste oryt in 10ml but much better if mixed it up to 30ml. I dunno if it's because the margin for error at 10ml is too huge so basically 0.2ml extra can affect the entire juice profile a lot or what. Since mixing new recipes at 30ml I found much more consistency in my testers than before.
Single flavour testers I will mix roughly 1% in 5 or 10ml depending on what I have.
A recipe that I am doubtful of 20ml
A recipe that I think should be OK 50ml
Stuff I like 100+ mil
I agree with you on your point of mixing smaller samples. I battle mixing small samples, even 20ml samples can pose a problem with the scales that I presume most of us are using, especially where the % is quite low.
When I was mixing with a syringe this was not a problem, suck up what you need and squirt it in. With the scale it doesn't register each and every drop, hence my "samples" have got bigger since mixing with a scale.
