I’ve recently discovered the joy that is soy milk. Milky goodness without the ookey real milk aftertaste. Yum! It goes so well on Costco Crack, aka granola, I could consume the two all day long. But I’m trying to still lose a few pounds so I’m trying to control my cravings. On the carton, it says you can store it for up to a year unopened and 7 days opened. Well, I can’t remember for sure when I opened this last carton but it’s got to be right up there at the 7 day mark. How do I know if I’m going to be flirting with disaster with my next bowl of Crack (er…granola)? With real milk, it becomes pretty obvious. With soy milk… 😕 Anybody know? ---

The advantage of soy milk is when it goes off it tastes exactly the same as when it’s fresh. 😉 ---

That comforting…or disturbing…to know. I wish the weather wasn’t so cruddy or I’d go get some more. Next time, I’m stocking up. ---

If you want ideas for how you can remember in the future when you opened your soy milk, I’ll be happy to provide some. But I don’t have any experience with soy milk. There’s this part of me which suspects that really, a day or two more than seven is still not a big deal, especially if you’ve been using some each day, but I really don’t know that that’s true. ---

Yeah, I’m sure I’m not going to die of some weird food poisoning if I drink it on day 8 or 9. Still, I was curious on what to look for. I’m going to keep a marking pen in the kitchen so I can put the date on future soy milk cartons. ---

[Here is what Silk Soy Milk’s website says about freshness and spoiling.](http://www.silksoymilk.com/FAQ.aspx#AL-6) Note that they say they don’t _guarantee_ its freshness beyond 10 days after opening, but that it has been known to stay good for longer periods. I know I’ve kept some in the fridge for several weeks and it was fine. No weird odor or texture, tasted just like it did on the day I opened it, and no ill effects after I injested it. In fact, until I read this thread and checked that site, I wasn’t sure it _could_ spoil. Ignorance fought, I guess. ---

I have had spoiled soy milk. There were _chunks_ involved. I think you’ll be fine if it pours freely and smells and tastes normal. ---
