I don't really consider it a sulfery taste, no. It's also hard to describe it because I don't really want to remember it, haha. I have some more in a Grolsch bottle I could try, but I don't want to. I'm scared to put it in my mouth again.
Here's some potential problems I had, as I spotted them:
1) Too long in both fermenters.
2) My siphon hose I bought for the auto-siphon was a bit too big, and wouldn't siphon correctly, so I basically ended up pumping it out when I moved from primary to secondary. I soon tired of this however, and just poured it over gently, trying to stop before getting the sludge off the bottom in there.
3) I tried to move the bottling bucket after I filled it up and bumped the spigot and it started to leak all over the floor. I had a full bucket of sanitizer, so I swished my arm around in there for a few seconds, then put it down in the beer to screw the spigot back on *facepalm*
4) I didn't use a real recipe. I just threw stuff in my brew pot.
5) I screwed up all of the above things, and so by the time I got to bottle it, I really didn't care how it turned out.
So I guess I consider it a small success that it actually came out the other side as beer, albeit a mostly undrinkable one (for me at least).
