Both were one gallon batches, adding water to the honey until it hit the one gallon mark. Given there was less honey in my glass jar, there was probably slightly more water in the jug. I did make a "one gallon" mark on the plastic bucket, which is probably not as precise as I think it is, but it's close enough for me.
The mead is very cloudy at this point, and I did see some signs of fermentation when I racked to secondary, so I probably should have waited a few more days, as
Beerontwowheels commented. I was reading about off flavors when the mead sits on the yeast cake for too long, so I got worried. Obviously, wanting to avoid that if possible but having it sit an extra two weeks probably wouldn't hurt anything.
I'm planning on taking another gravity reading in about a week, and then re-rack if necessary to get a secondary yeast cake gone. Then I'll bulk age until clear, which I'm assuming will take roughly six months.
Thanks for the comments - looking forward to trying these in a few months. Probably going to put together a cyser this weekend with some honey I found at a farmer's market in Kenosha - apple blossom based, so I'm pretty excited about this one.
