<human>: Can you give me the gist of the text in a nutshell?

Franzia boxed wine.  

I cook with wine often, but don't use a whole lot, so a box will likely last me a year.  I bought a red and white boxes last september, and opened them within a week of one another.  How long can I expect them to still be good?

I thought the point of them was so they don't go bad, but someone once told me to try to use it within like 4-5 months of opening.  I'm well past that now, and don't want to ruin any cooking this weekend by using bad wine.

Next, Mae Ploy Sweet chili sauce.  I usually just buy these little bottles of it, as I use it in a marinade with soy, srirachi, garlic, and sesame oil, to marinate flank steak.  But I got my hands on a few industrial size bottles the other day for really cheap.  The back says no preservatives added, so just wondering if this is something like ketchup that won't go bad anytime soon, or if I need to use it rather quickly?
<bot>: = How long does boxed wine last after opening?  And does Mae Ploy sauce go bad, it says it doesn't have preservatives, but it definitely has some ingredients I can't pronounce.
