I don’t look at brands with stainless steel water bottles, but I do look at steel quality. I only use 18/8 or 18/10 stainless steel, and I never get a taste from them. They also never rust and are super durable. I recently replaced my cracked naglene with a 32 oz 18/8 single ply bottle. I’ve been using it every day for two years and it looks brand new, but I only put water in it.
