Trader Joes and Aldi are owned by the same German company. Many of their items are the same: same ingredients, same size and same shape packaging, just different labels.
“Theo Albrecht owned and was the CEO of the Aldi Nord discount supermarket chain. In the US he owned the Trader Joe’s specialty grocery store chain. His brother Karl Albrecht owned the Aldi Süd discount supermarket chain. The two chains originally were a single family enterprise until a friendly division of assets in 1960. Aldi Süd operates the Aldi groceries in the United States. Aldi and Trader Joe’s, while owned by the brothers, have separate and distinct ownership and operations.
