Is this label telling the consumer that it is best to consume the drink 7 to 10 days after opening it?

Picture of juice carton label

I know what they are getting at, but I feel like it should say "Best if consumed within 7 to 10 days of opening". Is my suspicion correct?

This is what I perceive like the label is really saying

       1    2    3    4    5    6    7    8    9   10
   (Opened)                        (Best consumed here)
  • No, it means you -don't- want to consume it -after- ten days, and may even be bad as early as 7 days.

    Instead of saying "within 7 to 10 days of opening", why not just "within 10 days of opening"? Strange construction of sentence.

    What it says is that if you consume it before Day 7, it will not be at its best.

    It doesn't mean that it will be bad after 7 days (although it might be bad after 10 days). It just means it won't be its best. May 7, 2013 at 16:49

    This is about taste, not safety.

No. You are wilfully parsing it as though "7 - 10 day" is an interval to which within applies. But within does not take an implicit interval like that. You could say "within the period 7 - 10 days", but that's the only way I can see to get the meaning you want.

Which leaves the alternative (and clearly intended) parsing within x days after opening, where x is specified loosely.


The "Within" portion of the phrase is intended to eliminate the interpretation that you are trying to impose on it.

(within 7 days .............)    
(within 10 days .........................)
(within 7-10 days ..........?????????????)

The extended portion of the range covered by . is definitely good; the portion covered by ? is probably good, but not guaranteed.

The "after opening" is probably there to frustrate the pedants who would insist that "within 7-10 days of opening" includes a total of 14-20 days:

          (within 7 days of ........................)
                               (within 7 days after )
