Cold kefir or room temperature?

Hi! I have a question: can you leave kefir out of the fridge at room temperature to drink? Does it spoil or go bad like regular milk?

Whenever I make it, I always keep it in the fridge and drink it cold—150ml every morning on an empty stomach.

However, I feel like it tastes better at room temperature (which only happens when I first make it and have that first glass). It’s just so cold otherwise!

What do you guys think? Can it be left out like regular milk? Have you tried it?
