[Resolved]  Nestle Milo — Bad after taste

I bought a tin of 500mg Milo for a baby shower with some friends. I was so embarrassed when one of my guest had came up to me and asked me if I bought an expired tin of milo as it as a very bad after taste, when I did taste it I also got a very bad after taste and had to apologise to my guest was the most embarrassing moment. I always thought that Nestle sold quality products and had no idea that the standards as dropped. I am very disappointed as I use to love having Milo until this bad experience.
