This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)

Ordered on a whim.  My first "Grove Square" purchase.  Great for the family's occasional cocoa desire.  Being a K-Cup it's fast and easy.  Was a little worried the cocoa might leave some after taste in my coffee, so far so good.  Great cup of dark, rich cocoa.  Maybe could taste a LITTLE better if it was from a gourmet brand you mix yourself with steamed milk.  The ease and simplicity, and lack of clean up, make this a better option for me.  Will order again.  Nice to see it on subscribe and save.

This product previously ordered and excellent but this time tasted old and was very hard---finally threw it away.  Still have not figured out how I ever got it in first place as ordered another product from Amazon and somehow got this  as well?????
