Born under the Mexican sun in 1899, Sol is a brand with a strong heritage and a close association with sunshine. It is only natural that the beer incorporates solar energy into its production process.
The sun has always been the heart and soul of Sol and now it is able to harness its power. Following the installation of 9,212 solar panels on the roof of Zoeterwoude brewery in the Netherlands, solar power plays an important role in the production process of Sol. This is a milestone in the brand’s journey to reducing carbon emissions and becoming more sustainable.
Brand owner Heineken partnered with MCC Cwmbran, UK, in search for a solution to communicate this important initiative to its consumers. With its strong link to the sun, the team at MCC had the solution in its photochromic label.
Photochromic ink changes color when exposed to sunlight. The color shifting ink is activated by UV light (typically sunlight), allowing the consumer to view the packaging change first-hand. The UV light charges or gives energy to the ink, this creates the color change, once the energy is used the ink returns to its clear state.
When exposed to sunlight, the Sol label reveals a hidden message to the consumer.
