I think the concern initially was that cold brew may be more prone to bacterial contamination than normal coffee, because it has lower acidity and the water used to make it is not boiled. But like the study you linked found, it seems to be safe at least when refrigerated.

Maybe there’s something I don’t understand (I don’t drink coffee at all), but coffee is antimicrobial and doesn’t need to be kept out of the food safety danger zone. I should think it would take an extremely long time to grow pathogens.
