You’re gonna love it Phil! I don’t listen much to Aphex Twin or Ian Svenonius but sippin’ romorantin makes me feel like I’m proper edgy. 
The thing that makes no sense in my wine life…
I feel like the differences in Champagne between cuvees and producers are so miniscule I don’t really get it— yet it’s the biggest increasing region in my cellar this year and I can’t wait for my RdJ allocation. 
It took me 50 years to get to where you’ve started out!
I love half bottles, I need half bottles, there are no half bottles (well, very few).
I understand that this is because a large majority of wine drinkers don’t want them. But I don’t understand why they don’t. Two good glasses for two people. How convenient if people want to start with a couple of good glasses and then split a bottle! How convenient if you only want two good glasses for yourself? Cutting back on your drinking? How about a half bottle!
Cost may enter into it: A half bottle should cost 55% the price of a full bottle (cork, label, glass, foil all probably cost almost exactly the same as for a full bottle… the wine costs exactly half the price). I get turned off when a half bottle is 2/3 the price of a full bottle.
And I get another point, which is that plenty of people want to taste the same bottle the next day.
Still.
The only benefit for me is that I really like wines with bottle age. And when I do find half bottles, they tend to have bottle age, because nobody wants them. I’m retired from the wine business, but still have contacts and can buy wholesale. I’m about to order a case of 375ml bottles of a 2021 Sonoma Zinfandel… and from the same producer a case of 375ml bottles of their 2019 Sonoma Chardonnay!
For a while it made no sense that I bought 2/3 White Burg and 1/3 Red Burg and 97% of the time I opened Red. But I have since resolved that discrepancy and stopped buying all the Whites that I probably will never drink.
Do you buy mostly singles or doubles? Fear of opening the bottle at the wrong time and then not having any when at peak could be why.
No, just general wine worry. A few times it’s my ‘last one’ but I have the same freeze when I have 3 or more.
I have gone completely full circle over the last 45 years. When I got into the wine business in the late 70s, I loved all the lavish, rich, oaky Chardonnays from California, transforming into white burgundies by the mid 1980s. Then it was a steady diet of Italian whites/ French whites that never saw wood (or minimal). Loved the grassy Sonoma Sauvignon Blancs, also fell in love with Santa Ynez Sauvignons.
Now I find myself going back to oaky Chardonnay for some damn reason. I just crave them. My partner hates them, so I don’t get to enjoy them as much, but every chance I get, I open an oak laden Chardonnay.
Don’t sell yourself short - you might grow up someday!
