I would have to disagree with the temp control part (at the very least) on that list. .
There's less need for it where I live (UK) - never very hot and not much seasonal variation. However, I do keep my ferments cool as I've had nasty hangovers from rare summer heatwaves.
I do think temp control helps a little. But it doesn't take beer to "the next level" - plenty of brulosophy experiments to back that up.
"The next level" is 99% placebo effect. That's not to say placebos don't work - they can be very effective, especially where subjective judgement is concerned.
Like I said, I made pretty good beer in a cool basement and get that the climate is different as a whole in the UK. But calling fridge/controller temp control placebo effect just isn't accurate IMO. I do see it as 'next level'. It offers an array of benefits (reducing heat generated from fermentation, better control of esters, phenols and fusels, precise temp schedule for beers that need it, better foam at cooler fermentation temps, etc.) Regardless, I don't doubt that your beer is good. We can agree to disagree and that's perfectly fine.
I used to agree 100%, as it was what I read everywhere on the internet. The problem is, the brulosophy experiments just haven't found much of an effect. I still do temp control, I'm just not convinced by all the claims made in its favour any more.
Historically it was a great way to maintain sanitary conditions as cool ferments excluded most bacteria and wild yeasts. Keeping those out meant a cleaner ferment and less funky flavours.
The idea that fermenting warm allows yeast to express it's character better through esters is dubious, I think. I need to see empirical evidence of perceptible effects - anecdotal doesn't sway me any more.
Happy to be proved wrong as it's very easy for me to control fermentation temp with my setup.
That point was that esters are more easily controlled by being able to control fermentation temps precisely, not an argument about warm vs cold effect on esters. As for Marshall, I appreciate his contributions but don't take them as gospel. Or any other one person's for that matter.
