I tried to slightly release some of the gas from a bottle this morning but released 2 pints of nettle ale in less than a second instead.
The interior of my shed, my fishing tackle, tool box, knives, the terrier standing at my feet and myself got soaked. Then as I stood there soaked it started to drip from the ceiling on to me so I took a bottle and got out. I put the bottle in the fridge and left for the day.
This evening a hunting friend and I drank the bottle and it was worth the effort. There's a slight smell off the ale (if you'd call it ale) but it's very tasty.
Try it.
