Bottle-Neck Fit The stepped bottle insert is the key fit component of this wine pourer. Because bottle-neck profiles vary, buyers should evaluate the insert directly against the intended bottle instead of judging compatibility only by the overall pourer length.
Separate Air-Return Tube The slim return tube gives incoming air its own path while liquid exits through the main stainless steel spout. This structure supports smoother pouring and more consistent flow performance during use.
Assembly Consistency The stainless steel spout, bottle insert and air-return tube work as one assembly. For repeat orders, the relative position and fit of these three parts should remain consistent, since they directly affect bottle fit and pouring performance.
