There are 3rd party steel filters for them. I started using one since nowhere nearby sells the things and ordering filters off Amazon got annoying. If it makes a difference in the flavor I can't tell, but it's much more convenient.
I do it simple - upside down method, add coffee (adjust amount to your taste), and I add a small amount of cold water first, just enough to wet the grounds a little - just to bring the temperature down to a little below boiling (because I add boiling water). Stir, let it steep for a minute or so, then invert and press - slowly (put one hand on the plunger then rest your other hand on top of the first, that's all the pressure you need).
Tried it this morning with the 2015 recipe. brewed 2 cups and worked great. Got a lot of flavor and balanced acidity. Consistently between the two cups was excellent. Usually I brew more volume so I made the 2 cups but 2 was a bit much.
Yeah I was just playing around. The recipe makes around 8oz of coffee. Which is actually just fine it just takes a bit of adjustment since before I would fill up a 12 oz cup.
I'm not a huge French press fan because of the difficulty cleaning it and grittiness of the coffee. Perhaps I'm not doing it right but it seems like a pain to use. Also I don't really need that much coffee in the morning.
