Where can we source wine bottle screw caps rated for 5-6 bar pressure in the UK?

Members recommend contacting these closure suppliers for high-pressure wine bottle screw caps:

- **Guala** — mentioned as a screw cap option for pressure-rated closures - **Bostocap** — recommended by community members for screw cap sourcing - **Labrenta** — suggested as an alternative supplier to explore - **Herti** — noted as a current supplier (one member sources GPIs from them, so they may handle screw caps too)

When contacting suppliers, be specific about your pressure requirement (5-6 bar) and confirm they stock wine bottle screw caps rated to that specification. Lead times and MOQs will vary by supplier.
