Kuleana Rum Works: Rum Is Entering Its Transparency Era

Kuleana Rum Works, the Hawai‘i-based distillery known for its additive-free, award-winning rums, today announced the release of “An Open Letter on Additive-Free Rum,” written by Founder & CEO Steve Jefferson, addressing why rum is now facing the same scrutiny and market shift that reshaped tequila a decade ago.

Consumers across spirits are demanding more honesty about how products are made. Additive-free labeling has already transformed tequila and is reshaping whiskey and RTDs. Drinkers now expect producers to protect natural flavor instead of masking it, and bartenders increasingly use transparency as a measure of quality. The letter positions rum as the next category entering this accountability cycle, as more consumers begin to question undisclosed sweeteners, flavorings and added color.

Tequila provides the clearest precedent. Producers who embraced additive-free methods helped premiumize the category, while brands relying on undisclosed additives now face growing skepticism. According to the letter, rum is approaching the same turning point. Jefferson explains that Kuleana Rum Works was founded on additive-free principles: growing heirloom Hawaiian kō (sugarcane), fermenting and distilling fresh juice at lower proof to preserve natural character, adding nothing after distillation and holding all blending partners to the same standards. Every rum — whether distilled in Hawai‘i or sourced — is verified additive-free through independent lab testing and supplier documentation.

“Consumer expectations are changing fast across spirits,” said Steve Jefferson, Founder and CEO of Kuleana Rum Works. “People want honesty in what they drink, and they’re rewarding producers who protect natural flavor rather than covering it up. Additive-free isn’t a trend — it’s becoming the standard, and rum is now facing that shift head-on.”

Additional detail in the letter underscores how production choices such as fresh juice fermentation, low-proof distillation and a strict no-additives policy create transparency and flavor integrity that align with what the market is valuing.
