I’ve been experiementing with pigment extraction using anil (Indigofera suffruticosa) that I’ve been foraging from disturbed areas here on the central gulf coast of Florida. I’ve used your blog post extensively throughout my experimentations as it has been the most detailed and thourough in explanation. I just wanted to share for any other people that might read this who are curiously beginning their own indigo adventures, that the acidic hot water extraction works extremely well. And that despite all of the forums, sites, videos, articles, etc. online that say fermentation of the leaves takes anywhere from a day to 5 days, be aware this relied heavily on the temperature of where you are. I’ve had a completed extraction happen in as little as 1-2hours with the steeped leaves starting in cool water and with no acidifying agent and set in the midday Florida sun. So if it were me, I would check my fermenting solutions quite often the first few times but also the hot water method is wayyyyyyy faster and easier to control in my opinion and experience! Cheers
