For the first six months of my now one-year vaping journey, BWB was absolutely my #1 go-to vendor. I still have 23 BWB juices in my stash, most purchased in that initial six months. Over the past six months, however, BWB juices have lost some luster for me. I don't taste perfume in them, but my palate does register a characteristic flavor signature to many of Don's tobaccos, and that flavor has sort of paled for me. I still consider Backwoods Brew to be a great vendor, and Don's clearly a juice alchemist, but other juice vendors have come along that hold my attention more now---VermillionRiver, NiteLiteVapor, PrimeVaping, CopperCreek, just to name a few. Don's coffees (Café Mocha, Espresso, and Cappuccino) are still yummy to me, but the tobacco flavors have been eclipsed by those from other vendors using natural extracts or absolute. I don't not like them, I just like them less than before.
When I first bought some Perfumer's Apprentice flavorings last winter, they all tasted perfumey to me, which I hated. Now they don't (new purchases of PA flavorings, I mean). I don't know if the flavorings have changed or if I've changed, but that unpleasant floral taste is no longer present, and the flavorings are now much better for DIY.
