Micro-Agglomerated Corks
Known for its stability, these micro-agglomerated corks are made of small cork granules that are compressed to form a uniformed single mold. They compress less easily than natural corks. These corks are great for home winemaking kits. Cork insertion is easiest when using small hand-operated corkers.

Neutrocork® is a new generation natural cork closure that offers homogeneous stability. They are typically used for early consumption of wine (up to 2 years).

Cork Dimensions
Wider corks have a tighter seal which are sometimes difficult to insert with handheld corkers. Longer corks limit the amount of headspace available in a bottle. In general, most bottles can handle various cork dimensions to create an acceptable seal.
