Steve? Steve, is that you?
Case A -- If you bring a bottle in a bag, but tell people beforehand that you're going to bring it, that's single-blind.
Case B -- If you bring a bottle in a bag, but don't tell them beforehand that you're going to bring it, that's double-blind.
Case C -- If you don't bring a bottle in a bag, and don't tell them beforehand that you're not going to bring it, that's double-double-blind.
Case D -- If you don't bring a bottle in a bag, but do tell them beforehand that you're going to bring it, that's double-cross-blind.
Case E -- If you bring a bottle in a bag, don't tell them beforehand that you're going to bring it, but they see it subsequent to your arrival, that's three-halves blind.
Case F -- If you bring a bottle in a bag, don't tell them beforehand that you're going to bring it, and no one notices that you've brought it, that's five-halves blind. (Case Fb -- If you bring a bottle in a bag, don't tell them beforehand that you're going to bring it, and no one including you notices that you've brought it, that's infinite-blind.)
I'm unclear about what happens if you bring the wine in foil. Or, what if it falls out of the wrapping and shatters on the sidewalk before you can taste it? What if some people know you've brought it and some don't? What if the bag is constructed of material that's visible to people who can see non-standard parts of the electromagnetic spectrum, but invisible to the normally-sighted?
Boy, this blind stuff sure is hard!
But...but wait, now I see tasting order is crucial to the definition:
So if someone notices that the only bagged wine is at position 5 in the tasting, it's no longer double-blind to them, it's half-blind...unless they also didn't know it was going to be in the tasting at all, in which case it's double-blind minus 3/16ths for a pre-identified position. If they did know it was going to be in the tasting but can't see the bag due to the aforementioned electromagnetic variance, it's two-thirds blind. If they did know it was going to be in the tasting and can see that it's in position 5, but can't figure out exactly where it is in the tasting despite that second bit of knowledge, that's loboto-blind. And if they didn't know the wine was going to be in the tasting, can't figure out what position it's in if it is in fact there, and have the strangest feeling that a mole is squirming up their pant leg, that's 6.02214151023-blind.
But no, you've cleared it all up for me. I've got it now:Single blind is when people know in advance that a wine will be part of a tasting, but the wines are bagged

OK, so it's double-blind because, 1) they don't know you've brought it and, seeing it amongst the other wines, they have no reason to suppose any wine at all has been brought by you, and 2) they don't know where it is in the tasting and it's in a bag, thus preventing them from figuring out where it is in the tasting. Got it!so you don't know exactly where it is in the tasting

Yes, as this exciting and very helpful thread has clearly demonstrated! I worried for a moment or two that there was disagreement, but now I see that this isn't the case. Thanks, Brad! It's all clear to me now!It is widely used and accepted amongst wine lovers
