Just “blind” would be any kind of blind tasting. The term “double blind” for wine tastings in which you know nothing about the wines has been around for a long time, just google the term. Lots of results. While it might be the same term as double blind studies in clinical drug trials etc., it has a different meaning in this context.
I myself prefer the terms “half blind” where you know the wines, but not their order, and “full blind” where you don’t know anything about the wine. However, I can see “double blind” used to differentiate it from a normal “full blind” where one might get some kinds of subtle hints or other means of deduction, ie. bottle shape, who brought the wine, etc., even if nothing explicit is told about the wine - and in “double blind” all these kinds of elements are eliminated as well.
