did you mean to post in the DIY section and your post magically ended up here?
but if you meant does MBV offer DIY, why absolutely, positively, and as a matter of fact they do!
i had a few sub-par juices from MBV lately, so after i called my congressman and left a million tweets somewhere, i realized that all i had to do was order some MBV flavorings or some of my favorite MBV juices that were somewhat lacking in the great MBV kind of way. so i've been adding some MBV flavorings to my MBV juices and as of today, my MBV Dulce De Leche is back up to par.

i'm still working on my MBV Rootbeer, whilst i await the steeping of my MBV Peanut Butter, Coffee Liqueur and Cheesecake.
that's just me. i think you can find some recipes and suppliers in the DIY section. btw, did i mention that MBV has DIY supplies?
i, myself, am considering some DIY. but as the flavors that i want to replicate are, in fact, MBV flavors, i think i'll just some my flavorings from them...from the MBV DIY section on their website.
i checked with Mr Spock, and he affirmated that would, indeed, be logical...
