(Capcom's primary storyline)
Reichwein is the name of a company operating in 21st Century America. A number of Reichwein-branded boxes could be found across Tall Oaks. A Reichwein sign can also be found in a bar, suggesting it is a producer of alcoholic beverages.
Reichwein appears to be a reference to Mark Reichwein, the localization editor for Resident Evil 6 and a number of other modern Resident Evil titles. This would thus be an easter egg.
