Recommendation for bottling:
up to 2 years: Agglomerated
up to 4 years: 1+1 or Colmated
up to 5 years: Synthetic
up to 20 years: Natural

Agglomerated
Agglomerated Wine Corks are ground cork that is bonded into a solid shape. Agglomerated Wine Corks are available in two lengths and are suitable for wines to be opened young (within 2 years after bottling).

Colmated
Colmated Wine Corks are a medium grade natural cork that has the crevises filled with a resin made from cork powder creating a smoother surface. Colmated Wine Corks provide very good sealing properties and are an economical alternative to Natural Wine Corks.

Synthetic
Synthetic Wine Corks are FDA grade plastic wine corks that cork wine bottles up to 5 years. The Synthetic Wine Corks are among the best quality in the world. Synthetic Wine Corks are available in two sizes, regular length and short.

1+1
1+1 Wine Corks consist of an Agglomerated Cork center (ground cork) with Natural Cork slices on both ends. 1+1 Wine Corks are the best selling wine cork in the USA because they are an economical alternative to Natural Wine Corks.

Natural
Natural Wine Corks are derived from the highest quality Cork Oak periderm (or bark). Three quality grades of Natural Wine Corks are offered and suitable for long term wine storage. The quality grades include First, Super, and Extra. All corks are always thoroughly washed and treated to defend against cork taint.

Screwcap
Many Vintners are using screwcaps over the traditional cork due to the low cost of bottling and the lowered risk of the consumer receiving a tainted "corked" wine. Most use the aluminium screwcaps, but there are some that use a plastic screwcap. The screwcap also allows the consumer to store an opened bottle without leaking until they can finish it. Both Screwcap types are secured with a perforated seal which easily snaps when first opened.

The Zork
This is a plastic strip off used quite often by Australian vintners. This too is a low cost low risk bottle top. The Zork also allows the consumer to store an opened bottle without leaking until they can finish it. You need fingernails to open the initial stripoff seal.

Wired Bulb
This cork is used solely on Sparkling Wines. The cork is bulb shaped and can be made of the cork types above or plastic. The plastic bulbs are convenient for resealing an unfinished sparkling wine. The wire surrounding the bulb ensures that the cork does not blow off during shipment and handling.
