Tanduay is a Filipino rum brand that typically contains 40% alcohol by volume (ABV) in its standard dark rum offering. This 40% ABV level is common for many rum products globally and makes Tanduay comparable in strength to other standard rums. Tanduay also produces variants with different alcohol contents—some specialty or flavored expressions may vary. The 40% ABV figure applies to their most widely available dark rum product, which is the traditional core offering that built the brand's reputation in the Philippines and Southeast Asia. Always check the specific bottle's label, as different Tanduay product lines or regional releases might have different alcohol percentages. The brand has been produced since 1854 and is one of the Philippines' largest rum producers, known for affordability and accessibility across the region.
