If you’re short on time, then some grocery stores sell pre-made products like Demi-glace Gold. People who have time up their sleeve but don’t want to make demi-glace themselves can also search online for a range of products. There are demi-glace products made by well-known brands such as Heinz, Knorr, and Maggi but these are mostly focused on chefs in the foodservice industry. You could also try bouillon or consomme as a substitute in a recipe, but they have a much milder, shallower depth of flavor.
