Puck prep! Three different ways!

These are just three different methods I tried for puck prep in this video. It's not a thorough scientific review; I just wanted to see what the outcome would be. I definitely drew inspiration from the amazing Lance Hedrick recently video. I don't have a blind shaker or autocomb or anything like that, so I did this with the tools I had.
The metal mesh (part 1) using,can be time-consuming and may seem silly, but whenever I have the patience and use this metal strainer, the result is excellent. It reduces total time, increases extraction yield, and despite the higher extraction, the coffee is much less bitter and much sweeter(grind size is really fine for this coffee i used ,in part 3 as you can see the the shot is nearly becoming choked!).
In all three methods, the grind size, coffee, water, temperature, etc., were all the same.
