Glass Lined Thermos?

hi all, i make my 3 cups worth of bulletproof coffee in a thermos with the butter and oil in it and sip on it throughout the day, shaking it before pouring etc... but it occurred to me - is it bad for the coffee to be inside a METAL thermos?  if so i might try to find one that is glass lined or something ...

  • if you use it long enough, it'll  be lined with coffee stains so no need to worry


     


    personally, i wouldn't worry about it too much

    I do  something similiar with a stainless steel thermos. I would avoid aluminum.
