To kegcarb or not to carb if taste is possibly Diacytl?

OK newbie and Son are learning this brewing thing. Caveat, I never drank beer much but now I've tried a few of the small batch brewery beers I recently realized I really like Beer! Just not that stuff they sell for $8 a case. I'm helping with the research and supervising mostly.

After about 20 days bottle conditioning the first batch I think it's still not great beer, the carbonation is weird. If ice cold it still seems almost flat to me but when he opened one warm it fizzed out like a GEYSER - & maybe because it's a Pale or Wheat Beer it seemed KINDA weak.

SO, he brewed a new batch with a Rouge Dead Guy box and after fermenting for 20 days or so he went to keg it and he intended to share it for the Georgia Florida Game with his friends. But on the day before the game he was moving it from the carboy to the keg and it was still hazy. So he placed the carboy in ice to see if he could crash clarify then racked it to the keg. Gonna carbonate it, but I said did you taste it? NO… EEK … so I tasted it and it seemed a bit sour, I thought it may have been an infection, So I said OK it may be bad but don't pitch it - The HBT Guru's always say "patience lets the yeast fix the flub ups" right? I say don't serve it, Let's wait and see what it may be, he used some CO2 to remove the oxygen off the beer in the closed keg. OK, now I'm doing research… I read about diacytl and because it was certainly an apple cidery taste that made me think infection I'm wondering if it's actually that "green apple" flavor instead? The beer was likely fermenting at 80- 85* because the house was 76 and he placed the carboy back in it's box to keep it dark. Of course we are now aware that's probably not a good temp. But back to the issue. Should we "condition" it by leaving in the keg uncarbonated for longer and taste test it weekly or just go ahead and carbonate it in the keg then let it sit for a week or two and try it then?
 
Sounds like high fermentation temps to me, time will not fix. Chalk it up onwards to the next batch.

I used the (swamp cooler) cheap igloo square cooler with a styrofoam lid and frozen water bottles method for cooling for years. Recently bit the bullet and got a mini fridge with temp controller, I'd never go back. If your going to stick with the hobby invest in some form of temperature control.

Cheers
 
Ahhh,Thanks for your reply!

I have a Terrapin Rye cubed clone I decided to jump in the deep end with. It's in my closet right now keeping it cool (70*) with frozen water bottles tucked inside a Costco soft side grocery bag cooler that almost comes to the top third of the fermenting bucket. I really hope I didn't waste a lot of good grains and Malts..not to mention four different varieties of Hops. Sigh…
 
Keep at it, I dumped around 40 gallons of finished beer last year.

I don't homebrew for cost, but rather fun/fresh awesome beer. The hobby is so rewarding when you have fresh beer better then the beat up bottles at the corner store.
