I don’t do inverted. I just add coffee and fill up the aeropress with boiling water. Then I put in the plunger to keep the water from dripping. After a minute or so I’ll do one swirl to get the grounds to sink to the bottom. The I way for like five to ten minutes and press slowly.
I use one filter and usually go for a light roast. I also tried stirring with a spoon but I seem to prefer the swirl
