Hey, sorry for the delay here. All I know is what's below. He arranged a fresh bag to be sent which was nicely milled and got DPD to collect it from me. Should never have gone out like it but at least he resolved it with no cost to me. "This is from an older batch as the more gritty Red Sumatra was milled by the Sumatran farmers, I can only presume we have come across a barrel with that strain in it. I can arrange for a collection if you want to swap it out?"
