What is this brown deposit at the bottom of my Oil can?
This is just fine material from the grinding process that got through the filters and settled over time. It's pretty normal, it just means this company's filtering process isn't as effective as your previous brand. There shouldn't be any food safety considerations with that, my only consideration would be that suspended fine particles will lower the burn temperature of the oil some. There doesn't seem to be that much in there, if you are having no problems using the oil then you look good to go.
