All of the whiskies in Seagram's 7 Crown are aged for a minimum of 4 years, some in new charred white oak barrels and some in used charred white oak barrels. The maturing inventory is monitored by expert blenders for flavor development.
As the inventory gets near its usage age, blenders lab-produce products using different percentages of inventory components until the exact flavor profile of Seagram's 7 Crown is achieved. This inventory survey and lab blending is a constant process and is one of the reasons the flavor of Seagram's 7 Crown has remained consistent.
In 1857, a distillery was founded in Waterloo, Ontario. Joseph E. Seagram became a partner in 1869 and sole owner in 1883, and the company became known as Joseph E. Seagram & Sons. Many decades later, Samuel Bronfman founded Distillers Corporation Limited, in Montreal, which enjoyed substantial growth in the 1920s, in part due to Prohibition in the United States. In 1928, a few years after the death of Joseph E. Seagram (1919), the Distillers Corporation acquired Joseph E. Seagram & Sons, and took over the Seagram name. The company was well prepared for the end of Prohibition in 1933 with an ample stock of aged whiskeys ready to sell to the newly opened American market, and it prospered accordingly. Thus despite its earlier Waterloo history, the Seagram name is most closely associated with the Bronfman family. However, it is not correct to say, as is often done, that Samuel Bronfman founded Seagram, since the Seagram name itself pre-dated the company he founded.
