So after 8 years ,just recently got into diy . I did try a couple recipes a few years ago after I bought some flavorings and nic , but just couldn't get into it. This time I bought a scale, more flavorings and more nic. Some of the 10ml flavorings came in plastic dripper (not dropper) bottles, but most are in glass with no way to get it out except a syringe or pipette. My question is, will they keep better in the glass? because I really like the plastic because I can just drip it instead of using a syringe....I was thinking of transferring the ones in glass all to 10ml plastic drippers like the others that came like that.. if I was doing by volume, glass wouldn't be bad, but diying by weight, it's a pain...or do they sell little droppers that can screw into the glass? That wouldnt be to bad
