Has anybody tried using this with a Venturi style pool vacuum? If so, how well did it work?

I found that these bags work every bit as well as the more expensive ones that our plumbing sub sold us. I will definitely reorder them.

if you pour water into this how long does it take to drain with just gravity?

Don't know, we pump the water thru it with a pump. I think it would flow right it, with just gravity. A great filter.

Is this bag "food grade"

Yes it is by definition of “Food Grade”

Can this be used to filter cold brew coffee?

Not sure. Its ised to filter sediments from water so I'm mot sire why not. But I would think it is for cold water only.
