There is no objectivity in taste. Coffee drinking is a spectrum of preferences from flavor profiles delivered by growing, bean blending and roasting practices to acidity, particulate matter, strength, caffeine content, additives (milk/sugar/etc), and other subjectivity.

I personally don’t enjoy most cold brews, or cold coffee in general, as cold coffee tends to allow more fruity flavors come through, which I do not enjoy at all in my coffee experience.

I however, would not turn down a cold brew if that’s all that’s available. I mean, hell, I’ll drink a cup of black from a rundown diner that’s brewed from folgers and been sitting on a hot plate for 30+ minutes. And if that’s somebody’s favorite cup of coffee, I’m not gonna judge them and tell them their coffee is inferior.
