One wine near the $50 mark but can be found for a bit less is Evesham Wood Cuvee J Pinot Noir. This estate vineyard near Salem, Oregon produces outstanding and complex wines every year. Check out the story about the yeast they make it with on the website. https://eveshamwood.com
I’ll take your requirements literally, especially the “open hours in advance” (which eliminates a lot of wine). Barolo is my pick. There are many under $50.
I love Fontalloro, but absent 15-ish years of age I don’t necessarily think of its strength as being “complexity” so much as consistent “deliciousness”. It’s tempting to me to conflate the two characteristics and ask myself, well why do I find a wine “delicious” if it’s not “complex”. But I think I do enjoy many wines purely based on a flavour profile and texture that I find appealing even while not considering them to be particularly “complex.” In younger wines, I tend to find complexity only (with a few exceptions), in lighter-bodied wines…Jura reds, Beaujolais, some lighter-styled Nebbiolos (Gattinara, Spanna, and the occasional Barolo/Barbaresco that drinks well young), Nerello Mascalese, and Burgundy.
Yes, I agree with this, John. For example, I have a weakness, some might say, for Rochioli, both the SB and the PN’s. On the right occasions, I enjoy them a lot, but I would not call them complex.
