Did you use 15# of honey for 1 1/2 gallons? 12-15# should make a 5 gallon batch.
Yep, I would grate the orange peel and add it to the current vessel. I'm not a fan of things floating in my beverage. You can control the flavor in the secondary and then stabilize it in the bottle. If you put the peel in the bottle it's going to just keep oxidizing and at some point, assuming you don't drink that little jug in one sitting (
) it will start to get pretty harsh.
As for clarifying, man, honey is so hard. I find it never really clarifies, or at least is past that "fresh mead" taste by the time it ever will. And the temps... yeah, honey is just so hard to ferment. It's not supposed to, so you've got that against you straight from the get-go. Did you use a mead yeast? The best luck I've had with mead (and I've made less than 10 batches in my brewing experience) has been with Wy'east's mead yeast and once you start getting close to the 15# for 5 gallon ratio it's really a challenge for even mead yeast. I've tried Champaign yeast and ale yeast with less than pleasant results. Even with mead yeast, the temps like to be in the mid- to upper-70s, and it was pretty finicky about fluctuations. Even with everything optimized (my best one I injected O2 pre-fermentation), the primary fermentation lasted a month and I started drinking it after another month in the secondary, but it never really attenuated the way I'm used to seeing beer or wine must.
