It was especially egregious. Is he that bad at food, too?
This is going to get me in trouble, but what the hell...I'm going on vacation, and won't have to deal with the fallout until next year.
When I started writing in Boston, we had four critics. The one no one could stand (and I mean no one, but he was the best writer of the group, and certainly the most famous) only reviewed once per month, so he wasn't that useful except for the high-end restaurants he mostly reviewed. He did OK with wine when he deigned to mention it. We had another critic who was fairly good with wine and a pretty incisive food writer, but he was not only not anonymous (something I think is overrated, but that's another issue), he was pals with rafts of people in the industry. He probably shouldn't have invited multi-restaurant GMs to the premiere of his play, for instance.
The guy who wrote where I did fancied himself a wine expert. He was not (it was amazing how many times he ended up with either merlot or Chianti in his glass, even at Sardinian, Catalan, and Cantonese restaurants), and he suffered the same problem that Sietsema is exhibiting in the linked thread: a genetic inability to admit a lack of expertise. He was a good critic aside from a reflexive disdain for high-end dining, which made him very useful in one narrow group of restaurants, and only marginally reliable outside that box.
And then there was the other one, who was a horrid restaurant critic and even worse when it came to wine. ("Was" because the reign of terror is now over, though I don't know if the successor is an improvement.) I had more than a score (at least) of restaurateurs, wine directors, etc. insist to me that said critic did not drink alcohol. Maybe it was true, maybe it wasn't (Levi might know, though he probably shouldn't say if he does); I had lunch with the critic once during an interview, and there was no alcohol. But I can write said critic's wine coverage in my sleep: "Chez Joe has a good selection of wines at varied prices, with some bottles priced well into the higher ranges, and a short list of well-chosen options by the glass." (That's the long form; often, wine was entirely ignored.) The beauty of this, I guess, is that it doesn't mean a damn thing. I mean, hell, for someone who knows as much about wine as the critic in question (or Sietsema) does, Smith & Wollensky has such a list. It's an all-purpose trope, and mostly reflective of the bulk of non-wine-specialist wine writing.
The "incentives," however...on those, I can give a bit of insight. Journalists, as a rule, don't have the disposable income to explore many wines of note. Certainly none of the "important" wines, and decreasingly few of their replacements. (There's a whole rant here that I just erased because I'm not going to be around for the next few weeks to have the argument.) This affects how they view wine lists in an obvious and dramatic way. They also, as a rule, receive enormous pressure from their editors, who are also paid like journalists and have similar views of expensive wines, but are less personally invested in the wine and thus have even stronger feelings about what's "too expensive." So even if a critic took a more sensible approach to a wine list, an editor would likely protest. (Certainly they express the same protest to the actual wine writer, when such a beast exists, all the time. For me, in the late nineties, it was "try to keep the bottle prices between $10 and $15 dollars, and see if you can find some below $10; none of our readers are going to spend more than that." Yes, an exact quote. The advertising and marketing departments had a different opinion on their demo, but that didn't seem to hold any weight with my editor, his editor, or the editor-in-chief.) And furthermore, the number of non-wine publications that are eager for expense reports that include $20/glass wines number, at least in the States, between zero and zero. With the occasional exception of no one, and the notable standout performance of fuck-all.
So, you're now wondering: yes, but why can't they at least learn about this sort of thing and write about it properly even if they can't expense the wines? Well, they don't care, so that point's moot. But assuming they did, how do you propose they do that, given the above-mentioned income issue? (And now we're back to the rant.) (And we're also missing another rant about reflexively idiotic New York wine retailers who promote asinine asceticism in their wine critics. Man, this channel sucks...all the best stuff's on cable.)
Yes, the research ability for what you ask exists at the Times. (Maybe. I'm no longer quite sure.) But the will or the interest? Likely not.
You'll get the very occasional critic who "gets it," usually as the result of prior training. Craig LaBan, for example, seems to understand wine, but then again he's in a city where it's a lot more complicated to write about it. The disclaimer here is that I know the guy (not well), and I happen to know that he is indeed the beneficiary of prior training before restaurant criticism was his career. But on-the-job training? No way the Inquirer's paying for that, especially now.
