SCGC Koa Proprietary Seasoning

“SCGC is privy to a proprietary seasoning procedure that captures the colorful golden chocolate richness of this Hawaiian national treasure.”

I have seen this claim in several listings across the web over the years and was always curious what this ‘procedure’ might entail. The latest one I found is in an Eddie’s Guitars listing. (https://eddiesguitars.com/product/acoustic/acoustic-guitar-categories/acoustic-electric-guitars/santa-cruz-baritone-professional-d-model/)

I am not necessarily asking for someone to divulge this proprietary seasoning process but I am certainly curious what might be. I imagine it might have to do with some oxidation process that brings out the color before the finish goes on? I searched for this question here but didn’t see it. My apologies if it’s already been asked before.
