Try a dedicated cider yeast next time. Is it possible that smell came from the Nottingham selection? No need to sweeten with a dedicated cider yeast, in my experience.
The first two times I did cider I regretfully used Nottingham as well. Neither came out that well.
Most commercial cider is gross. I liked my dry cider a 100 times better than Angry Orchard. I wasn’t at all displeased with the result and the sulfur smell was completely gone when I bottled. Of the flight pictured, my wife liked the cider best and it isn’t because she doesn’t like beer. She will drink anything from a golden ale to an imperial IPA. She doesn’t prefer stouts as much as I do, but can appreciate certain examples like Uncle Bear’s Peanut Butter Cup Stout. So I think the cider was pretty good. As far as Nottingham, I think it leaves a flavor that I can’t taste. Marshall from Brülosophy was throwing all kinds of shade at Nottingham for an off flavor he gets, so I think it creates some compound that is light or unnoticeable for some and off putting for others. Another example of this phenomenon is citra hops. Some people can’t stand them, but for me they’re quite pleasant. On the other end of the same scale, cascade hops taste insipid to me and a lot of people say they like them very much.
Anyhoo, the reason I am not so into cider is I really enjoy all the drama on brew day with the mash temps and hop additions. Also, I just really like beer a lot. I like martinis or old fashioneds or wine, but 9 out of ten times if I have the choice, I’ll choose beer.
