Weighing foods packed in water

Factual Questions
1

While pondering a jar of pickles this evening, I began thinking about foods packed in water or other fluids. Since everything is packed by weight (not volume), is the fluid included in the net weight of the product? If so, isn’t this a bit unethical? I’m certainly not going to drink the pickle brine!* If the jar comes up short on weight, they could add a few ounces of brine instead of another pickle, couldn’t they? Unfortunately, my triple-beam balance is packed in the closet, so I can’t perform the simple experiment that would clear this up in minutes. Besides, I already ate a pickle or two … urp

[sub]I think this is slightly different than the case of fruits and vegetables where you know you’re paying for parts of the produce that are inedible - rinds, cores, stalks, and such[/sub]

I think you have a labelling problem there.

I am eying a jar of Haywards (The Original) Sweet Onions In Vinegar (Mild And Crisp).

On the upper left side of the label it states as follows:

Net Weight 454g
Drained Weight 245g

I now propose to reduce the Available Drained Weight by a pickle or two.

Mmmmmmm. Very Tasty.

On the jar of Vlasic pickles in front of me, yes. The size of the jar is 16 fl oz, and it contains 9 1 oz servings. That leaves 7 oz of brine left over, if you assume that pickles have roughly the same density as water.
