I won't use garden hose water. The taste is there. I've drank a garden hose beer too. The taste was there; big time.
Maybe with some super high quality garden hose there won't be a taste, but there are safer options for such little money.
And safer, yeah, they're still finding lead in garden hoses, and BPA too. That little endocrine disruptor has been found at levels 20 times higher than what's safe for drinking.
