I didn't see it mentioned in this thread so I thought I should point out that elevation, air quality, climate conditions, and a host of other factors will all play minor roles in shaping the flavor of the tomatoes. All the factors can be reproduced either through matching chemical composition (for air and soil), climate control, or the use of a hypo- or hyper- baric chamber. One would have to be ultra dedicated to the authenticity to really have a complete go at it.
