Sand-nice video!
Looks like you have found yourself some nice bottles there and judging by the size of that dump, you may be finding a bunch more. You did keep most of the better ones. Stoneware bottles are always good, also keep the bottles that are embossed with names so they can be researched. As others said, the cork tops are the older ones you want to find, though some screwtops can be good depending what they are. That broken shard at 6:15 was a real heartbreaker. I would have grabbed that short brown stubby bottle that you threw back down at the end part of the video, it is interesting.
You should get yourself a probe ("spear") to use to help you find where the bottles are. I never dig without one and even if I have no digger with me I use the probe to dig the shallow finds out with till I can return later with one.
This hobby is addicting and beware as you may now be hooked! Check out some of my albums in my public profile.
