Müllermilch has various flavours - my most favourite flavour is chocolate, followed by strawberry and vanilla. There are also other flavours like banana, coffee, passionfruit and so on. But as I have mentioned before, I am just not that adventurous - For my milk and ice-cream, I normally never go beyond these three 'safe' flavours (well, except green tea or sesame for ice-cream - but they don't have these flavours in Germany ;)).
What I like about Müllermilch is, the taste is not too overpowering and sweet yet flavourful, especially when served cold. My favourite Australian milk brand is Moove. But I think Müllermilch tastes even better!
