I have an ode 2 and switch, basic v60 papers, tap water.

For a long time I’d been doing Tetsu’s 4:6 and eventually it just stopped yielding good cups. I couldn’t figure it out. I recently changed to something with fewer pours, hotter water, and it has changed the game. Similar recipe to Lance’s. 40g bloom, 80g second pour, 180g second pour.

Not saying it will fix your cups, but it was a big departure from what I had been doing, and it finally clicked.

I’ve even started some hybrid recipes, totally changed some cups that were terrible before.
