I brewed a VERY weak partigyle a few months back and when it was done it was a light crisp tasty beer with a TERRIBLE after taste. I mean it was so bad this stuff has ben setting in the beer fridge for months and I just pick around it and hope someone else will drink it. I wanted a beer just now and wanted something light so I decided to try one of these. The taste is still good and the after taste is pretty much gone. So once again NEVER dump your beer. You never know what a decade or two can do for it lol.
