**Blackberry (Duomei) 0.2%/0.4% (1-4-23)** -- STRONG, STRONG, STRONG is the word of the day with this one. My initial tests at 0.4% had a very clear soapy, almost perfumey aftertaste. Fine, BACK to the drawing board, fully reduced to 0.2%, and re-tested. The flavor strength overall did reduce, and SOME of the soap and perfume reduced as well, but it was still somewhat present. This was fairly odd, as I have rolled with some of the strongest MF flavors with little to no issues, so this MAY be a flavor issue, and not a strength" issue per se. There did seem to be a oddly different blackberry hiding behind the soapy overtones, and it's possible, if you were to go even LOWER, you might be able to resolve it, but at that point, it would be so far reduced, it may just be unusable. I did not reduce any further below 0.2%, which in a 10ml tester, is 1d. I've come across AND overflavored plenty, so I'm very well versed in reducing my way back to sanity. This one, may not be ready for prime time. Fully reduced it smelled ok, but tasting it re-yielded the soapy-ness. Going to plant this one @ **2.0/10**."
