First I want to endorse Randy's Saturday live-discussion program, which I visited recently. The format resembled a phone-in radio talk show on wine. I hope to lobby more people I know, who I think would enjoy participating, and are seldom short of words.
Mark L? Dale? Rahsaan?
In the recent session, Robin and I both touched briefly on
varietal labeling history in US wines. To reiterate my point there, Schoonmaker and Lichine are known in US wine literature for promoting varietal naming in the 1930s as a practical standard, absent other, established naming conventions (like the place-named wines of the old world). This was part of their larger post-Prohibition and pre-war crusade to rally US interest in domestic wines and their potential. Among other things, the crusade spawned a landmark 1941 book,
American Wines (Schoonmaker and Marvel; New York: Duell, Sloan and Pearce) which many people refer to who are seriously interested in the history -- I recommend it (of course it is out of print, like most books at any given time, and, also of course, it is available used). If I recall, Haeger's
North American Pinot Noir (first edition, 2004, ISBN 0520241142 and an essential book for fans of that grape) describes the varietal-naming efforts, though in a quick look I couldn't find the mention there. Other authoritative sources on US wine history do too. Seff and Cooney's chapter on "Legal and political history" of California wines in the monumental University of California Press
Book of California Wine (Muscatine, Amerine, and Thompson, editors, 1984, ISBN 0520050851) cite Schoonmaker's varietal-naming promotion of the late 1930s. They say it lent growing importance to the 1935 US government standard for wine labeling and advertising (still effective, with modifications) which required any varietally-labeled wine to contain a majority of content from the named grape variety. (75%, from 1983.)
Below (by way of further recommendation) is a sample of the remarks on wine legalisms in the 1941 book. (Some of that books's comments, on likely wine-growing regions and varietals for example, are strikingly prescient; its affable parodies of "wine hokum" among snobs and armchair experts have scarcely aged, and resonate still today.)
Finally (in case the practice is unfamiliar to anyone) I post ISBNs whenever possible because you can copy and paste them immediately into an online book search, or just Google "ISBN xxxxxxxxxx" which sometimes catches online mentions of the book too.
A label is submitted and approved for a California wine made from Riesling grapes: the Federal Government does not know and is apparently in no position to find out, whether this wine was made from Riesling grapes or from Thompson’s Seedless. If not made from Rieslings, the wine may have been made and the labels ordered by a grower who is convinced that his grapes are Rieslings (“Father always said that the grapes in the north forty acres were Rieslings”) or by a grower who is committing a deliberate and conscious fraud. The Treasury Department apparently believes, and far too many lay citizens also believe, that it is possible to make people honest and intelligent and well-informed by publishing a book of regulations or passing a law. -- Schoonmaker and Marvel, 1941
