Conventional explanations of the distribution of winemaking regions em
phasize the influence of edaphic and atmospheric environments of the v
ine. This paper argues that legislation that reflects the political po
wer of the prestigious winemaking areas has had a major impact, especi
ally in France. The appellation legislation of France, and the assumpt
ions underlying it, are established. It is conceptualized as a form of
territorialization devised to regulate and capture advantages to some
of the participants in the industry. I analyze the influence of the F
rench principles and assumptions in devising the European Community an
d California legislation. In particular, I consider the manner in whic
h the underlying environmental determinism is used both to explain the
distribution of prestigious wines and as criteria to establish wine r
egions. The distribution of vine varieties in France and California il
lustrates the tight control evident in France compared with the laisse
z-faire policies in California. Some evidence of converging patterns i
n the two territories is apparent.
