Jerry has sent me samples from 3 different batches of unflavored VS WTA. For those unfamiliar with the VS designation, it stands for "Very Special" and represents the generation of WTA being produced by Aroma since around the beginning of January 2014. While I have declined to praise past generations of WTA as being as good as the small batch custom WTA that I produce, the VS WTA is different. The difference in quality between Aroma's VS WTA and my custom WTA is so small as to be effectively negligible. The three samples sent are all in VG and identified as: CAF11414 - 23 mg AF1514A - 21 mg AF11214 - 23 mg For reference, I will be using a 24 mg WTA in VG that I produced myself in a small custom batch around 3 months ago. The WTA isolate has been stored in the dark and sealed. I mixed it down to 24 mg today. It will be referred to as "reference". Reference - 24 mg The deviations from the standard 24 mg concentration in the Aroma samples are due to the fact that while the WTA itself comes from production batches of WTA, these samples were mixed down separately from the regular production bottles. I would have rather Jerry kept them all standard at 24 mg, but to expect him to do everything I'd like... well, not gonna hold my breath. Still, the levels are all approximate enough to the standard 24 mg concentration as to be "close enough" for all but the most fussy observer. My review of these samples will be done in multiple posts presented as my impressions are made. Lets begin with color: AF11214, CAF11414, and the reference are basically identical. AF1514A is lighter, remarkably so. Granted it is only at 21 mg, but that's hardly enough to make a significant difference. I am rather pissed at Aroma for daring to make a WTA lighter than mine but there it is in living color. More to come.
