You can tell right away that Ernie put time into Rouxgaroux, sourcing quality leaf, applying his casings, playing with aromas, arranging and rearranging the chords. The man is an artist. These tobaccos are all very nice, expertly blended to form a smooth, flavorful harmony. You cannot dispute the quality. I was troubled, however, by the blend's overwhelming acidity. The tin note is almost pure vinegar/acetic acid. Acetic does something very interesting here, besides acting as a preservative/antimicrobial. It adds a feeling of significant strength and body without coating your whole mouth in tar and nicotine the way stronger blends do. It's rather brilliant. (Cheers to Ernie, I have not seen this done before. He's the Heisenberg, a.k.a., Walter White, of boutique micro-blending.) The acid makes the smoke feel "fuller", adding weight and texture, giving it such a substantial mouthfeel without blowing out your palate. Dousing your tobacco in vinegar is something of an acquired taste — every single puff tastes like it has salad dressing on it, and it does ghost the pipe — but it is not a gimmicky innovation. Vinegar has been used in pipe tobacco for a long time, having featured prominently in many of the "codger blends" cherished by generations of Americans in bygone eras. Look to Cringle Flake, for example. Sutliff uses vinegar as a flavoring agent in that one, paying homage to blends from the 1800s which used it as a preservative. I was not a huge fan of Cringle Flake the first two or three times I tried it, because I couldn't wrap my head around the notion of vinegar in my pipe, and I'm still not wild about it today. But Sutliff uses a lot less vinegar than I find in Rouxgaroux, so Ernie is up to his old bold tricks again. Maybe my pound came from the bottom of the stock, but it is *f u l l* of vinegar. Just one bowl left acid burns on my tongue. This is not the classic tongue-bite, but genuine epithelial damage from concentrations of acid too high for my body's preferred pH levels. The burns were not deep and they didn't last more than a day, but it was still rather startling to wake up in the morning and see my tongue in such a state. The Virginia blend has some great nuance, definitely something to ponder and contemplate. The Perique was a bit on the lighter side for my taste, and I kept finding myself wishing for more. We don't get a components list with Rouxgaroux but I detect some light Cavendish in the mix, which is a good choice, a nice support to the main characters. Overall, it's a sophisticated, eccentric, wild-man type blend, which, I am learning, is what we should expect from Ernie Q. Despite the burns, I like it. I'm going to play around with a few approaches to solving the acid problem, then I'll really be able to enjoy it. I'll start with filters, balsa, charcoal, meerschaum, etc., and I'll experiment with drying time. When I break it down into smaller jars for aging, I'll leave a couple unsealed for a day or two to see if I can get some of the acetic to dissipate or evaporate. When I have some news I'll revisit and update my review.
