Design of the calendar started in July 2003. The final design of the calendar pays tribute to the native Filipino drinks like tuba, lambanog, basi, etc. which served as the foundation for the development of local Filipino liquors like Tanduay. It should be noted that Tanduay traces its roots to a small distillery that was established in 1854 by Elias Menchatorre. The first products of this distillery were spirits derived from the juice of the nipa palm. The calendar featured the origin and regional base of twelve native Filipino drinks - one drink for each month of the year. Each page also featured each of the twelve regular Tanduay products.

The dimensions of the calendar also were made in such a way that these symbolize the 150 years of Tanduay's existence. The calendar measures 15" by 24" - the 15 referring to Tanduay's 15 decades of corporate life and 24 referring to the numerals left when the two zeros in 2004 are dropped off. The calendar consisted of 15 pages again representing the number of decades of existence. The cover features a tri-colored horizontal band - silver (25 years), gold (50 years) and diamond (75 years) which when added together totals 150 years. Finally, the text describing each native drink in the inside pages contains 150 words.
