Things that go boom in the heat

I got an email today from a reader who wanted to pass along this info:
This winter I bought a couple bottles of Roots Epic to cellar. I had one about a month ago and it foamed out of the bottle like it had been in a paint can shaker. I should have known then to get the other in the fridge because last night I found my second bottle had exploded. I keep my beers in my basement, but with this hot weather even that is in the mid-low 70's. I was hoping you might be able to get the word out to anyone else who bought a bottle of this to get it in the fridge. Nothing like seeing sticky shards of glass that used to be a $20 bottle of beer.
Yup, warmth + overcarbonation = Boom! (Roots bashers, now is your moment. Personally, I'm going to protect my bottle with my life.)

Speaking of overcarbonation, I've been meaning to relate something I learned recently about yeast. I have been trying to breathe life into a particular beer involving disparate ingredients that will, until the beer is perfected, remain unidentified. They are not germaine to this particular story.

I wanted to dry this beer out as much as I could without resorting to wild yeasts. Using a standard ale yeast (Whitbread, if memory serves), I had gotten it down to about 1.018. It might have gone as low as 1.012, but I wanted to juice it with something drying, so I used Wyeast's Duvel strain just to finish it off. I didn't want much of the character of this strain, but I figured: there's so little sugar, what could happen? (Whenever you append to a brewing experiment the phrase "what could happen?", you should know things are about to get interesting.)

Well, I ended up with a beer that by all appearances was made exclusively by this yeast. It's got a massive head, lots and lots of effervescence, and that amazing Alka-Seltzer roil. To you long-time brewers, I pose the following question: what's the moral of this story?
  1. Duvel's strain, the Leroy Brown of yeasts, will bludgeon anything that gets in its way.
  2. The second yeast always dominates the profile.
  3. Whoa, 1.018, what were you thinking? If you'd finished it out more, the Duvel wouldn't have gone crazy.
  4. Some of the above.
  5. None of the above.
I await your experience and insight with interest.
