Quattro Stagioni (Four Seasons) are preserving jars made in Italy. They take screw-on lids.
The jars themselves are fine for canning with; it’s the lids that are the issue.
One-piece metal screw-on lids (aka “Twist-top lids”) such as those that ship with the Quattro Stagioni (QS) jars are not endorsed for safe home canning; in fact, they are recommended specifically against:
Can I use one piece canning lids for home canning? No. One piece screw type canning lids are not designed or approved for home canning use. This type of lid is used in food processing as a hot-fill-hold process under very strict time and temperature controls. In home-canning a two-piece lid is needed to let the air escape during the boiling water or pressure canning process. A one-piece lid doesn’t allow the air to escape resulting in blowing out the bottom of the jar or the lid to buckle.” 1
As well, with such a one-piece lid there is no way to test whether you have a seal that will keep the food inside safe without actually opening the jar, and breaking any seal that might have happened. Some have “buttons” pressed into the metal designed to help indicate if there is a seal or not, but this is not deemed sufficient. Nor does such a lid provide any way to tell if a hermetic seal has been consistently maintained throughout shelf storage. One-piece lids are fine for dry storage, or refrigerator or freezer storage: just not for shelf-stable canning use.
Note as well that these one-piece Quattro Stagioni metal lids are not supported for use in pressure canning, only hot water bath canning: “The Quattro Stagioni capsules are designed for use with hot water (max temperature 100 °) and not for use in the oven or pressure tank.” 2
There’s great news though: many of the Quattro Stagioni jar sizes will take standard mason jar lids and screw bands.
HealthyCanning.com passes the following information without re-verification at this point (summer 2015), as we haven’t had occasion to test it yet. A user on Linda Ziedrich’s site, A Gardner’s Table, has said that Tattler lids can be used on some, though not all, Quattro Stagioni jars [Ed: the commenter is speaking of Tattler lids, but Tattler lids are of course the same regular and wide mouth sizes as metal mason jar lids]:
The 1 liter jars and the 0.5 Anfora take wide-mouth ones, all the others require regular. The bottles and 0.15 jars use 56 mm dedicated caps obviously unavailable …. “
The commenter recommends to order some regular and wide-mouth canning jar screw-band rings from somewhere, to hold the Mason jar lids on during processing. He then gives some more detailed information about Quattro Stagioni jar mouth sizes.
- Regular size Ball or Tattler lids fit the 250 ml, 300 ml Anfora, and 500 ml jars [Ed: 70mm mouths]
- Wide Mouth lids fit the Anfora 500 ml, the 1 litre, and the 1.5 litre jars [ED: 86 / 88 mm mouths]
- Bottles (1 litre) and 150 ml jars require dedicated 56 mm lids made only for Quattro Stagioni jars.
The commenter concludes:
I use Tattlers with the 500ml, 300 ml, and 1 litre jars. The few one-use metal lids I’ve tried worked fine too. You’ll need the Mason screw bands, though.” 3
Quattro Stagioni FAQ: Accessed March 2015. Note that the restriction mentioned is on the lids aka caps; they say in Italian ‘capsule’, which means ‘caps.’ ‘Le capsule Quattro Stagioni sono progettate per essere usate in acqua bollente (a una temperatura massima di 100°) e non per utilizzi in forno o autoclave.” See the FAQ in Italian. ↩
