I have 8 meters of 1cm thick aluminum tube and I thought why invest in a copper chiller when I can build my own chiller, aluminum has high thermal conductivity, my only concern is that it might change the flavor? Give it a metallic taste? The reason I think there might be something wrong about this is that I've never seen a brewer use an aluminum chiller, despite the fact that aluminum is way cheaper than copper
