Juice in a bottle

I have been reading about a company in Northern Ireland that is developing a packaged shot of wheatgrass juice mixed with apple and lemon juice. Since most of what I have read about wheatgrass seems to say that it is best to drink it right after you juice it, I'm not sure how it will compare. It will most likely take weeks to reach the customer. I checked out the company's website, but they don't even mention it yet. I'm sure it won't hurt anybody, but so far the concensus seems to be that it doesn't stand a chance against a fresh-cut-and-juiced shot. Here is the link to the news article if you want to read it yourself. Please add a comment if you have any more info on this one!
