Q: What is the recommended maximum storage life after bottling with these caps?
A: screw top hand applied caps will never be 100% air tight. That being said, depending on the product, the shelf life will vary-These are not recommended for carbonated products like beer or cider. Wines would be best consumed within a few weeks, and spirits can last a bit longer
Q: Would this fit the S.Pellegrino 750ml bottles ?
A: the diameter appears to be similar but the thread pitch or depth is different
Q: Does the 28mm have a 400 thread (28-400) ?
A: these should be a 28mm 400 thread
Q: Do these seal and how if yes, for the purposes of selling items (such as vinegars or wine) in a winery?
A: the metal caps do have an inner wax liner that seals off the jugs from outside air and fluid leakage if turned. That being said, it is not a factory or safety seal and would not be 100% airtight for long term storage
Q: I ordered these to cap off a cylinder (I know - not their intended purpose), but they're just a smidge too small. Do you have anything that's maybe 30mm to 32mm?
A: The threaded cap sizes we have available currently are 38mm and 28mm for that we currently provide. There are some wine style and spirit bottles that use proprietary cap sizes that may not be available to order replacements.
Q: Do these caps fit a regular wine bottle from the liquor store or do they fit the special wine bottles? The Stelvin caps fit the wine bottles from a liquor store.
A: These caps can fit most bottles but there are some with a proprietary thread style or cap that they may or may not work on. We cannot confirm they will work on all commercial bottles from the store
Q: Is this for a standard size wine bottle
A: these should work on most 750ml and 375ml wine bottles with a 28mm thread. There are a few wineries that use a proprietary thread for the taller aluminum caps that would not be a guaranteed fit with these caps
Q: So these fit the 50 ml glass bottles?

A: The OD on these would be the 38mm. The best comparison for if these would fit your bottles or not is typically the size of a Bleach bottle cap to check the sizing since these will be a similar size but slight different thread type
Q: How do these get installed onto the bottles?
A: These are a hand twisted on/off cap. These will provide a liquid tight but not an air tight seal, Think similar to a fruit juice cap from the grocery store.

A: The caps will fit some bottles bot not all. Some store bought wine bottles have proprietary thread types that will not be able to be used with these style of caps.
Q: Do you have a similar cap that will hold carbonation? I'm trying to find caps for 750ml Perrier glass bottles
A: Unfortunately no. Most of the metal cap sealed bottles have proprietary lids that are unavailable for outside purchase to carbonate with. Any screw cap bottle to hold carbonation would need the snap sealing ring intact and are typically put on the bottles mechanically

A: These are not meant to hold pressure for carbonation, or be installed on a beer bottle.
Q: Will the 28MM screw cap fit on the 750 ml wine bottle?
