Wild Turkey Kentucky Straight Bourbon Whiskey

It has changed and is no longer that great taste – This was my number 1 bourbon until this last bottle I bought 3 weeks ago. I also bought a bottle of Nelson County Bourbon and this cheaper bottle tasted way better than the wild Turkey which also went milky when I left it in my glass and lost it's flavour. Never had that happen ever. Has anyone else had this happen recently? This leads me to believe that they ( wild turkey 40.5%) have changed it and are cutting costs. I will not be buying another wild turkey and will now switch to Nelson county. Less alcohol content (37%) but way better flavour. Both bought at Dan Murphy's Noosa.
