These corks are recommended for use with a floor corker for best results, although they may also be used with appropriate hand corkers that can handle synthetic closures. The firmer structure of synthetic corks benefits from the additional leverage and even compression that a floor corker provides.
Key performance characteristics:
Intended to keep wine sealed for about 12 months under proper storage conditions
Provides consistent insertion and extraction, batch after batch
Used by professional wineries for dependable results and uniform appearance
Because they are synthetic rather than natural cork, these closures do not require continuous contact with the wine to maintain a good seal. Natural corks can sometimes dry out and lose their seal if bottles are stored upright for extended periods. Synthetic corks are more tolerant of different storage orientations, which can be helpful for:
Short term storage or early drinking wines
Bottles that may be stored upright in cases, racks or on shelves
Tasting room or retail setups where bottles are frequently moved and displayed
Typical uses include:
Table wines intended for consumption within about one year
House wines and everyday pours bottled in standard 750 ml bottles
Test batches and small production runs where consistent sealing is important
