Flavour packets' expiring date - how far can we push it?

Hi Huelers!
I have some flavour packets expiring this month, one of them is already open.

My question is regarding the expiring date.

Is there any problem (taste, quality of ingredients, etc. ) if I continue to use them in the next 3/4 months, or should I strictly respect the date? :slight_smile:
And what about the closed ones?

Cheers!

Assuming it’s best before then you’re good. I don’t have any but id wager a small amount it’s bb and not use by
