So I just recently completed the main Nuka World questline and I got a heck of a lot of Nuka Colas stored up. Then I returned to the commonwealth and started doing quests I never finished. I got the Trouble Brewing quest and decided to keep Buddy for myself, because ice cold beer is nice. When I found out I could get ice cold Nukas... well... I was ecstatic. I gave the robot all my Nuka. Every last bottle. And they all came back ice cold.... At the time I was happy, but I just built a Nuka Mixing Station. You can't mix ice cold Nuka. I just wasted hundreds of Colas. Don't do what I did. KEEP YOUR NUKA WARM! Or at least don't be an idiot like me and put all your Nuka in.
