I used D-47 for all of them and Orange Blossom honey. It's tolerance is 14% and thats around where I wanted it to stop but it had other plans. If you only used 2 Habaneros I can't imagine what Carolina Reapers will do.

Its easy to get stuck on a rare card's theme or ability when building for limited formats (Prerelease/Draft/Sealed). Base your deck build on uncommons that share a theme and use the rares to supliment that instead of trying to build around one rare card. Once I started doing that my decks played better and didnt stall out if I couldn't draw the one rare card during a game.
Recently bottled a Peach Ginger mead that managed to get to 19% without permission. Tbf though I didn't try to stop it. I Have English breakfast, Chai, Black Currant, and Chocolate Vanilla meads that need to be bottled. Next plan is Pineapple Cayenne. I have Carolina Reapers growing that my friends want to try a mead of...might try a very small batch just to see if its feasible.
I think they're hoping it will be too spicy. They're the kinda guys who go out to find the hottest thing just to say they tried it. One of them found a 9mil Scoville pepper extract. They just want to say they tried a spicy mead. So I'm just going to keep to a very small batch so I don't waste any liquid gold.
