I have a small fridge in the kitchenette of my home office and it's thermostat seems to be poorly designed.
As the weather turned cooler, I was turning it down a fraction every day to stop the fridge from getting too cold.
Then one morning, I checked the temperature and it had effectively switched itself off. I had gone too far and it was reading about 20c!
It took over a day for it to get down to the right temperature. I've been worried about the effect on my beer stash ever since.
But lo and behold, today I had a bottle and it tasted better than ever. It seems the temperature fluctuation has aged it perfectly.
I think I need a second bottle before it passes it's peak!
