I mixed a bunch of really small test batches a few days ago (3ml each) and finally got around to doing a quick taste test. First I used my RDA with a single coil... quick wick, saturate, three draws, then remove wick, dry burn coil, and re-wick for next test. Quick and dirty. The I moved on to my little MTL mod/tank (Innokin EZ Watt/Prism T-20S) This helps me get a feel for how the juice will actually vape in my everyday setup. What I do is just put 1 ml in tank, vape it for awhile, then dump the juice and put some unflavored base in (70VG/30PG 12 mg nic) Sort of vape this awhile to "flush out" the flavor, then dump that and try the next flavor. Works great and at the end I take all the dump juice and do a "mutt" mix (just for kicks) vaping the "mutt" mix right now and it's great. The only exception was some Purilum "sweet tobacco" that I vaped on it's own. By now, I guess I've got a reputation as a sot of "nut job" but there is a method to my madness (and a madness to my method) Hey, it works for me
