THE RILEY/LAND COLLECTION
Apparently it's a thing. My coffee maker is a French Press. It's what I have used for years. I wasn't stirring the coffee when I poured the boiling water over into it, but one day someone asked if I could make them a French Press stirrer. I acted like I knew what it was - I mean, it is self-explanatory - and then I googled to see if that was a real thing or just something random this lady has asked for. It's a thing! Anyway, back to the reason you're reading this. I now give the coffee a quick stir and it dispenses the grounds more evenly, making the coffee taste better.
Why not just use a regular spoon? Try it. Once you crack the glass walls, you'll understand. I learned by experience on that one too.
