• The needle tip incorporates precision micro-porous flow channel design. When injecting inert gas (e.g., Argon/Nitrogen), the airflow distributes evenly and gently across the wine surface through tiny pores, forming a delicate cushion layer. This design avoids the bubbles and foam caused by traditional tubes directly hitting the liquid, achieving safe and efficient "dry" oxygen displacement.

FAQs:

Q: What is the material of this wine preservation needle? Will it affect the flavor of the wine?

A: This product features a SUS316L stainless steel​ tube body and a high-purity brass with gold-plating​ threaded connector. 316L offers excellent corrosion resistance and ultra-low gas permeability, being completely free of plasticizers. The brass fitting ensures long-term sealing stability. Both are food-contact safe materials with strong inertness, guaranteeing no release of any odors or substances into the wine, perfectly preserving its original flavor and aroma.

Q: Is there anything special about the needle tip design? Will injecting gas splash the wine out?

A: The needle tip incorporates precision micro-porous flow channel design. When injecting inert gas, the airflow distributes evenly and gently across the wine surface through tiny pores, forming a delicate cushion layer. This design avoids the bubbles and foam generated by traditional tubes directly impacting the wine, enabling safe and efficient "dry" oxygen evacuation. Even with a high fill level, there's no risk of spillage during gas injection.
