Wine (agglomerated) corks are used for bottling wine. Tapered corks are not used for this purpose.
What does "agglomerated cork" mean? It's the process by which these corks are made. It is simply
cork dust/pieces mixed with silicone and fired through a mold for conformity of shape and size.
Why not pure cork? Because pure cork is rarely uniform in shape, vintners can experience
TCA (cork taint) problems, thus spoiling their wine yield. Agglomerating corks helps to mitigate that problem to a large degree.
Cork Agglomerated: 8x1.5, 8x1.75, 9x1.5 and 9x1.75 These corks come pre-sanitized and do not require sulfating prior to use. A quick dip in a sulfite solution may aid in inserting these corks into bottles. Soaking these corks may cause leakage as the cork becomes saturated with sulfite solution and wine through the bits and pieces that are molded together.
Cork Synthetic and Duo-disk: These corks require sulfating prior to insertation into the wine bottle.
