HaHa that is real funny.
I hate that granny flower taste too, lol. I've had new FVF and SJF but did not detect it at all, perhaps they finally figured it out that they were tainting the SG blends. These were bulk boxes and tins, new from September 2017.
What I've noticed is that the new FVF is totally different from the 2012 batch I have and the batch from 2008 I have been puffing on. 2008 and 2012 are so sweet, almost candy sweet. The new batch is more bready with ginger notes. Both good but not the same at all. Its not an age change they are clearly different leaf.
