Bottle Conditioning - Old Bog Road

When a beer is really good, should I chill the beer, shut down the yeast?

I Brewed Revvy's "Old Bog Road".

4 weeks in the primary, 1 months conditioning in the bottle.
At one month it was incredible. Absolutely delicious. One of the best brews I have done. (Thanks Revvy)

Now I usually try to rotate my bottles into the refrigerator so that they chill for at least 5 days before drinking. The rest of the time they stay in the fermentation chamber at 68 degrees.

The last 12 bottles (24oz) have been in the fermentation chamber now for 2 months.

And now the beer is now not quite as good, it has lost it's smoothness, it is a little more bitter on the back end of tasting.

Any comments?

 

Interresting. I Had the same question

Specialy for a stout.

The first 2 months it tasted great.

But now, it's turning into a more waterish taste.

Will cold stop the degradation of the taste ?
