“Bottle too soon with secondary going on or overestimate the amount of bottling malt and you get a bottle full of foam or little popping sounds coming from yer basement...which is bad news because it tastes bad after you wring it out of a mop. Don’t ask me how I know that... ;-)”
Time for some family lore. My grandfather decided to take up bathtub brewing during Prohibition (probably more as a protest, than for the beer). He was a traveling salesman and had to leave town before the fermentation had completed, so he instructed my grandmother about bottling and left. She had a sweet tooth and decided the beer needed a bit more sugar before bottling up. The bottles were stashed in the closet at the end of the hall. A few nights later, they sat up in bed, startled by the muffled explosions coming from the closet. They were afraid to open the door and beer ran down the hall all night as the explosions continued. Grandma said they picked glass out of the closet walls for years. So ended the bathtub beer experiment.
...Time for some family lore....
My Dad’s father was in the Army serving stateside during WWII. Officers were then authorized to carry their service pistol (1911 Colt 45ACP) 24x7, even at home.
So one night, he wakes up to some noises in the bathroom. Grabbing his pistol at the high ready (barrel pointing up), he goes to the bathroom. He is startled by stepping in something wet and lets loose a shot into the ceiling.
When he turned on the lights, he found that some of his homebrew bottles had exploded...
