GREECE-OLIVE OIL

SIMIZA, Greece — In the olive groves around Ancient Olympia, the trees were once considered sacred, and in many ways they still are. Carefully looked after, they are described by farmers with a reverence that could match the language used by makers of champagne. So a proposal to blend some olive oils with cheaper vegetable oils has been met with anger and disbelief. The reform would be part of an effort to modernize Greece's battered economy. One pro-government lawmaker called the proposal a "cause of war," while olive producers in the fabled hills of the southern Peloponnese region worry Greece could spoil its signature export.
