America's Test Kitchen, which I consider the gold standard for taste-tests (and kitchen equipment tests, for that matter) tested vanilla extract. When their regular panel found little difference between real and imitation vanilla (made from wood pulp, by the way), they called in an expert panel of pastry chefs and ran the test again. You guessed it: The pastry chefs also found no real difference between real and imitation. One pastry chef, according to ATK head honcho Chris Kimball, asked that his name not be used because he didn't want to face the wrath of real vanilla purists.
They taste-tested vanilla in milk; 1 part vanilla to 8 parts milk. That is far stronger than the concentration in most recipes that use vanilla---which is closer to 1 part vanilla to 80-95 parts batter (or whatever).
