I’ve fallen even further 😅
My machine’s manual recommends using “oxygen whitened filters” and I used to stress this. Well the last time I went to buy filters the one place in town that used to sell them stopped. I decided I probably couldn’t tell the difference and bought the “natural” ones from the same company and I definitely don’t notice a difference.
I’ve got my ratio locked in; 60:1 and I weigh the water and beans every time. But other than that and a thorough cleaning and descaling on the manufacturer’s recommended schedule, that’s about the extent of my fussiness anymore.
