hahaha amazing! 
is that milk?
Looks like Milk to me; sounds and tastes great like it too and in a good old traditional glass pint bottle.
If the camera hadn’t have been focus trained on the Sheep - that’s why the cup is slightly out of focus - you’d have been able to read the small print on the glass bottle. 
Nice pic
Enjoy the cup.
Thank you Guido for you kind words and congratulating the Sheep with her prize.
