Some cafes pull longer shots, some shorter, and you can call them more lungo or more ristretto compared to the averages at other local cafes. But you need to to have a reference, based on a set of rules, perhaps like INEA's, before it makes sense to call a drink ristretto.
Alternatively, a barista can make either more ristretto or lungo drinks on the fly. This is rare; even more rare is doing it competently. A person like that can, with complete authority, call his or her varied drinks lungos and ristrettos.
+1 on Jim's pocket change.
Somehow I missed this thread in the holiday maelstrom. I agree with Jim that it's more accurate to talk about brew ratios and relative strength.
Also, while the article is right that some coffees can stand up to being pulled at a higher concentration and others cannot, it misses an essential point about current trends in cafe espresso: shots are being heavily updosed and pulled short so the coffee can be tasted through the massive amounts of milk in oversized cappas and lattes. A secondary reason is that straight shots can be shaded to the sour, under extracted side to avoid the bitterness that often results from poor technique.
The second paragraph of Jim's post really interests me. The article says you make a ristretto by grinding finer and/or dosing more. Sure, you can do it that way. But you can also pull shorter. My understanding is that this is how a ristretto or lungo is produced throughout most of Italy: pull shorter for ristretto, longer for lungo. I've confirmed this works, though the time window in which it works well is somewhat narrow.
Jim says it takes skill to make ristrettos or lungos on the fly, and I'm assuming he means by baristas who do so by adjusting the dose. I'm sure that method takes quite a bit more skill that simply running the shot shorter or longer, though some judgement comes into play with that, too. Presumably, the so-called ristrettos produced via the American and Italian methods will taste different.
Anyway, in addition to the terms not being well defined, even the technique isn't well defined.
