Introduction to Sandeman Wine Cellar: Sandeman Wine Cellar (Sandeman) was founded in 1796. In 1790, George Sandeman, a businessman from a wealthy Scottish merchant family, came to Porto during a business trip. , found that this was a good place to make wine, so he gave up running a coffee bar in London and opened a winery in Porto. He made use of the local high-quality water and grapes and the wine-making techniques taught by his father, careful ingredients, fine processing, and unique storage methods to brew the now world-famous "Black Cape" brand wine.
