Roman ways with wine...

[Virilis]

Howdy rangers!

Can someone please provide basic info about the use of wine by the romans. I mean how they diluted it, sweetened it, made perhaps warm drinks out of it etc. Did they drink it (diluted) after hard labour etc.? Is this book perhaps a good introduction to the subject?:

Thanks in advance!
