I love to drink red wine straight from the box.
I like it too, i think somalier is my dream job :D red wine color can range from intense violet, typical of young wines, through to brick red
We always just put ours in mason jars with ice cubes. We call it "grown up koolaid".
Hehe, thats a good thing to tell children :D the juice from most purple grapes is greenish-white; the red color comes from anthocyan pigments
I never knew that, I always thought it was because the grapes were purple. 
The pigment is form the stem or grape skin, the presence of stems during fermentation can lead to a bitter taste in the wine
I can see how that would happen. Bitter wine doesn't bother me though haha.
Thats how they make the taste different, particularly with hand-picked grapes, stems, and leaves are left in the mixture to change the taste
