Hey Dado, that's a great question! From my experience, 18 degrees isn't a strict minimum, but more of a guideline for many lager yeasts. 19 degrees should still work fine for a "low-temperature" fermentation, though it might influence the flavor profile slightly. It's all about experimentation! While you're experimenting with fermentation, have you ever tried playing Solar Smash online? It's a different kind of stress relief! Let us know how it goes. Cheers!
