Complicated one! The first one I shot in the rut when I started out stalking tasted awful, I could smell it while it cooked. However others who maybe don't eat it often enough thought it was lovely, I however thought it taste like urine! Anything that is shot this time of year has to go to the game dealer or friends, as I cannot have it in my freezer, especially when you compare it to the nice tastey prickets I have been stocking my freezer with early season.
THAT SAID.......I was on Scotland last week and shot a stag that was rutting, early on in his rut, and we had to break him on the hill. I was dubious about eating it, but it was delicious.
I shoot a good number of fallow every year but won't eat a rutting one any more!
