Oh, I had a spectacular one recently.
I think it was around mid May, I decided to make a load of sparkling melomel, I'd already brewed a few gallons and instead of pasteurising and bottling as I normally would, I just went ahead and back sweetened in beer bottles before capping and putting it all in my shed.
I'd forgotten all about it, there was around fifty (500ml, glass) bottles in total, note I said
was.
Cut to a couple of weeks ago, sitting in the living room watching TV with swmbo, we heard an almighty boom and the unmistakable sound of tinkling glass. I didn't think much of it, our neighbours are often up to shenanigans so I just chalked it up to that.
Went into the shed the next day to sort some other brewing stuff out and found it wall to wall covered in shattered glass and the unmistakable smell of spilled booze.
In my haste to both back sweeten and prime, I'd added 25g of honey to each 500ml bottle...I've been brewing for 30 years, I really should have known better!
Two weeks on and I'm still finding chunks of glass here and there
