I had the opportunity to be learn wine tasting from Robert Mondovi SR in 1983.
Unfortunately I was put on an antidepressant in 2000. It is the only one that works for me and the warning is alcohol will kill you. It reacts with the med and stops the electrical conductivity of the heart muscles.
I enjoy reds from central California. I have been to Paso Robles many times and there are hidden gems all over the place there. I am also a fan of Spanish wines also.
More of a bourbon guy myself, but I did try a merlot once and really enjoyed it. I was admittedly a few drinks in so I don't know how accurate my palate was by that point lol
