Per George Jensen stated well over a year ago that MacBaren is not producing the Peterson flakes. Irish Flake has been my number 1 favorite tobacco since it was originaly released. K&K did a stellar job after taking over from Murrays. I've smoked K&H's Stirling Flake and in spite of what many have said, in my opinion it is indeed Irish Flake. I've noticed yet another change in Irish Flake with the last 4 tins I smoked. It may still smell like IrF in the tin (noticeably weaker than the K&H version), but there is some other presence in the taste that I can't seem to identify. What I do know is after all of my years smoking IrF, it now nips at my tongue the way many of the MacBarens have a tendency to do. Perhaps MB is now producing the Peterson Flakes as well? Although a bit more expensive (but I've noticed two more flakes per tin with Stirling Flake than IrF), Stirling Flake for me is the same as the IrF I have smoked for years and obviously have gotten very used to. I wish someone from K&H, Macs, or whomever, would enlighten us once and for all!
