I find the skim milk different in taste in the States where I've travelled, compared to skim milk in B.C., Ontario or Alberta. I do find 2%-3% fat milk..richer in taste because it's been decades since I've drank it.I just despise skim milk. My grandfather used to call it Blue Death because it just tastes so bad and has a blue tint to it. I prefer 2% or whole milk, and half-and-half in my coffee or tea. No ice cream, though.
And I attribute to what the cows are fed, the soil in which the grass is grown. Taste of milk varies across Europe, etc.
I used to be lactose intolerant..simply because there was a time in my life I literally forgot to drink milk regularily.
I prefer gelato vs. ice cream of which neither I've had much in last 2 yrs.: I live in a city that doesn't offer enough quality handmade gelato or ice cream. Vancouver has more choice. Not Calgary: we're still stuck in beef mentality...ranch country of Canada.
