I would prefer you don't. A good recipe will tell the vaper it's profile without using visual stimulation or guidance or worse having me open a box of my favourite childhood biscuits in the middle of the aisle to see if I either forgot the taste or perhaps they changed the profile.
I hear you, but I thought about this also, there is a couple of problems here. So if I read the competitions rules they ask us to provide a cool name. So in my mind the only reason to do this would be to provide that on the table next to the juice. Contestants will be placing information about their profile into their names. So you already have a concern here.
The other things - to give out zero information does not really simulate real world DIY or DIY competitions for that matter. Where a person finds a few recipes that they want to test, read the profile description - and test the juice. If you go look at DIYorDIE competitions as an example, they test a juice based on how true it is to the profile. They also look at creativity on how ingredients were used. Some avid DIY'ers would love to geek out by reading the profile info and ingredients used.
Also to give zero information might have people confused - if you create a 3 fruit recipe that transcends into something new and exotic, a voter will have no clue what they are vaping.
Also if someone creates a potent menthol juice - a voter might want to taste that last to save their taste buds. Imagine a menthol juice is stacked right next to your juice in the competition, that could wipe out their taste buds when they have to test your juice next. (also some people hate menthol, coolant and tobacco) so we might want to be upfront it - so we don't let them try something they knowingly hate.
Just my thoughts, what do you guys think? We also need to know what the voters thinks who will be testing. So let us know...
