Ok, found it. Rubedo (and Rebis) recipe is available for after completing Practicum in Advanced Alchemy quest on Skellige (that's lvl 24). Mind you - completing quest alone don't cut it, you need to buy the recipe from alchemist. It requires White Gull to make, so you probably want to make it up front.
