I remember a high school French teacher claiming to try espresso we could just make drip coffee and double the coffee. Er, no...
Non non non! Tabarnac!
I don't think I've ever had a latte, but I suspect that I wouldn't particularly like them with all the milk.
The milk, if lactose-intolerant, can be a lot (unless, say, it’s one of the microfiltered varieties, which for me tends to be less harsh on the GI system).
I tend to drink French press coffee at home by itself (the caffeine, please). If, however, I’m out and about and choose to order something more fancypants (I’m more fond of cortados than I am lattes, as I can do without the foam), these tend to be the beverages for which I’ll treat as a light dessert: I’ll add a packet of brown or raw sugar (yes, very different creatures) to them, or else honey, if available. Otherwise, it’s just a cup of hot milk with some espresso in it. (Meh.)
