"When yellow fever struck Philadelphia in August of 1793 the blame for the epidemic was initially (and incorrectly) placed by Dr. Benjamin Bush on coffee beans that had been rotting on the wharfs. It is now known to be caused by a mosquito borne-virus."- taken from The Coffee Calender by Ricardo Levins Morales.
So don't worry, you won't be getting any yellow fever from rotting coffee. In fact you won't even come in contact with rotting coffee at VCC. We batch roast our coffees in small batches and keep our stock constantly fresh to give you the best quality coffee available.
