For the longest time I've wondered why my coffee tends to run either bitter or too watery. I even bought a fancy 64mm flat burr grinder, and noticed the problem became even more pronounced.

Everyone always says how important water is, and I figured my reverse osmosis water with an alkaline stage was probably fine, coming out of the tap at around 50 PPM. It turns out the ideal TDS is actually around 150. My water's TDS was too low. More info here: https://www.raleighcoffeecompany.com/tds-and-coffee/

Using a cheap TDS meter and water alkaline drops, I got my water's TDS up to around 150 PPM by adding a couple drops into my kettle, and brewed a cup of coffee with it. It actually made a difference! Lesson learned, pay attention to your water.

I don't mean this to be an advertisement, but I have tried a few metal coffee filters, and have not been able to find one that works as well as one from a company called Ovalware. Its the only one I could find that lists a micron size for the inner mesh (40 μm). I've found that this draw down time is faster than a paper filter, it is still slower than other mesh filters. And while it doesn't quite eliminate fines, it does a great job keeping most of them out of my coffee compared to other mesh filters. I've also not had any trouble with the filter coming apart at the seams, or getting coffee grounds stuck between the inner and outer layers.

Has anyone tried this filter? Or have you found other metal filters that you've liked?

I recently got a Hario Switch clone and a metal filter. So far I'm liking a recipe inspired by these YouTube shorts:

• https://www.youtube.com/shorts/rCj4hBDpY6Q
• https://www.youtube.com/shorts/dAWQPUVDKck

Recipe:

1. Start with 20g of grinds, stir to loosen the grinds and make a divot in the center
2. With the switch closed, add 150g of 90C (195F) water
3. Give it a quick stir and wait 1 minute
4. Add another 150g of hot water
5. Open switch

What is your daily driver recipe for your Hario Switch?

Everyone here talks about the Hario Switch. And I like the oils you get from a French press, so I want a stainless steel filter too. I had some good experiences buying a cheap manual grinder on Ali Express (Jaffee J1 w/ 7 core burr), so I wanted to set out to see if I could do the same with this set up.

Do you think this will work?
