Congratulations! You have just won a lifetime supply of milk, for the personal use of you and your household, to be delivered at intervals to your home. How would you like your milk to be packaged? You may choose among bags, cartons, glass bottles, plastic bottles/jugs, tins of evaporated milk or bags/boxes/tins of powdered milk.
Leave it in the cow.
Plastic jug over carton by a small margin. If it’s a free lifetime supply, who in their right mind would choose powdered?
Personally, I have always preferred milk bags because of the ultra-light, recyclable packaging. I used to buy it this way when I lived in North America, but where I currently live in Europe fresh milk is sold only in cartons and glass bottles. I usually buy cartons because only the expensive upscale brands are sold in glass bottles. (I suspect the reusable glass bottles are a bit better for the environment than the recyclable cartons.)
I don’t see my first choice on that list. Unless you count “jugs.”
A tie between cartons and plastic jugs/bottles
I’m not Canadian, what the hell would I do with bags of milk? I don’t think they even sell the pitchers people put them in here.
But anyway, plastic jugs. The handles are convenient, and you never suffer a ill-glued spout that doesn’t open properly.
I prefer plastic jugs. IRL, I always end up with cartons because of the shelf-life of ultra-pasteurized organic milk is good for me (I only cook with it, not drink it, though, so can’t speak to flavor), and that’s how it comes. I really appreciate the handles, especially when pouring from a full jug. Prefer to a half-gallon to a gallon, because I can handle a full jug with one hand.
For the purposes of this question, you can assume that you’re provided with the pitcher.
Jugs, it is so natural sounding.
Since I buy the cheapest store-brand by the gallon, the current plastic jugs work for me.
As cheese. (the cheesy answer)
I always buy the plastic jugs but if money and availability were no object I would probably go for glass bottles.
I’ve been thinking I’d give plastic bags another shot if I could pour it immediately into a tightly sealed glass bottle to see if it prevents the taste from going off. However, all the places I buy milk use plastic jugs so I haven’t bothered trying.
That whole bag arrangement looks to me like a mopping nightmare waiting to happen. I prefer the recyclable plastic bottles, like Fairlife comes in.
As for you Timmy, I’ve got 50 bucks says if you ever get the chance to try it that way you won’t be able to make yourself do it.
I kind of miss glass bottles, but plastic is undoubtedly better (for containing if not the environment).
I don’t drink milk as often as I used to though.
I’d feel less guilty getting cartons, as I’d want them to be single serve. Ideally, they’d be those flat box kind that can be stacked, as space is also a consideration. Bottles are usually not stackable and often not recyclable.
Glass just seems too bulky, and more annoying to actually have to recycle.
Don’t drink it but use it for cooking. Bottles, cartons, jars, I don’t care. No powdered, no condensed/canned. If I need condensed/canned I will reduce it myself, cooking it down with appropriate aromatics depending on what I’m using it for. Cinnamon for peach cobbler for instance.
In 20 years of serving milk from a bag in a pitcher, I don’t recall any spills. The bags fit pretty snugly in the pitcher, even when running low. Anyway, you can always use a pitcher with a lid.
:eek: 
As for the poll, I put cartons. For some reason the milk tastes better to me, maybe the wax lining in it adds something extra lol.
I voted for plastic jugs(screw-on cap please!). The empties are real handy for storing drinking water during hurricane season.
The idea of glass bottles is attractive, but only for nostalgic reasons. I haven’t seen those since the '60s when the milkman would deliver them to our house.
The bags seem very unwieldy - do the extras lie flat enough that you can stack them? And keeping only one quart/liter at a time ready in a pitcher seems doesn’t seem practical. Maybe if I poured four at a time into a large jug. 
Evaporated milk does’t count as “drinking” milk in my world. You use that to make pies or mashed 'taters.
Powdered milk could be an option if I was preparing for post-apocalyptic survival, but that’s about it.
A lot of people put it in their coffee, so if that’s the only way you ever drink milk, then I can see the appeal of that poll option. I suppose you can also add water to evaporated milk to reconstitute whole milk, though the flavour won’t be quite the same.
