Not well, red was smashed to pieces, white was broken in two.How did the wine fare?
I only just cleaned out the back pack today (I was just going to bin it however it's practically brand new). I removed the shards of glass by continually rinsing out the backpack with warm water until no glass showed and it stopped running red/pink. I'll let it dry for a week and hopefully it will be as good as new.
I will be extremely careful if I ever end up carrying glass bottles in backpack again, I plan on getting panniers.Incredibly lucky I'd say. Broken bottles would easily slice right through any backpack and straight into your flesh. There have been many cases of people falling with wine bottles and not surviving the horrific injuries they can cause.
Here's the pack before cleaning after removing the white bottle...
