Any updates from you guys? I'm going to bottle my batches this weekend since it's a long weekend for us.
Planning on letting it sit in the bottles for another few weeks before trying to drink it.
Right now it's coming along well. The blackberry one has become nice and clear! Looks very much like a Red wine. But the Mango one is looking more like a wheat beer, so I'm planning on throwing some bentonite in that one and seeing how it will clear up.
They both smell delicious, I really am looking forward to having these summer-time melomels 
So I didn't get to bottle my Mead a month ago like I said I would, ended up letting it sit for a bit longer, then bottled it this weekend.
Last Thursday I added Bentonite to the wine, to help with clearing it up.
Bentonite needs to be prepped before adding it to the wine, similar to how yeast is activated/re-hydrated (except using Hot water, instead of luke-warm). I vigourously mixed the Bentonite with water, trying to avoid any clumps, and put the resulting "Slurry" into a cool-dark place for 12 hours to sit. You can let the Slurry sit between 12-24 hours before adding it in, so that it fully absorbs the water and gets a nice positive charge action going to attract all the negatively charged particles in your wine.
After 12 hrs of sitting I slowly added the Slurry to my mead, mixing it carefully so that I didn't aerate the wine too much. It looked gross, but only after 2 hours of settling in the Mead, the Slurry started to separate and I got a nice division between the two.
Left it alone for 2 days, and the Slurry settled right down to the bottom of the carboys. Here's a couple pics of the bentonite separation right before bottling:


I ended up re-racking the wonderfully clear wine, and bottling it. In the process I ended up drinking a bit of both flavours. Both wines are dry, and has a very strong alcoholic taste. The Blackberry came out really nice, has a nice subtle flavour, while the other one didn't have much of a mango flavour at all. I perhaps should have added much more mango to the mix to get it to stand out, since mango has more of a lighter flavour to try to bring out.

I'm going to let these bottles sit for a little while to see how the flavours will develop, but all-in-all, my first batch of Mead/Melomel turned out pretty good. 2 gallons yielded 8 bottles. My next batch is going to be double that.
