I tried a recent bottle of Dickel No. 12 a few months ago. I was disappointed. I got a little cough medicine taste. I've never heard anyone else describe this taste. Maybe No. 12 is just not for me. I've never tried the scarce No. 8.
My first ever bottle of Dickel was a #8. I thought it had a distinct flavor that did tend towards the cough medicine flavor....still have some left.
This weekend i picked up a #12 so I will give it a go and also do a side by side and post my results.
