Port / Sherry Fortified Wine Bottles

Fortified-wine bottles share the dark, heavy character of red-wine glass but add features for their category. The classic port bottle has a pronounced bulb in the neck: as vintage port ages and throws a heavy crystalline deposit, the bulb helps trap that sediment when the wine is decanted, keeping the pour clear.

Because fortified wine is higher in alcohol and keeps for weeks after opening, many of these bottles use a bar-top (T-top) cork that can be pulled and re-inserted repeatedly, rather than a single-use driven cork.

Ruby, tawny and vintage port, sherry, madeira, marsala, vermouth and other fortified and dessert wines. Vintage ports meant for long ageing use a driven cork and the bulb neck; wood-aged tawnies and styles for earlier drinking often use a bar-top stopper.

Dark, near-black green glass shields the wine from light over long ageing. The neck is made either as a standard cork bore or with the signature bulb for sediment control; bar-top versions are sized for a T-cork. Glass is on the heavier side for both strength and a premium feel.

Filled cold; control fill height for the closure used. Vintage ports are laid down for years, so cork quality and a sound bore matter; bar-top styles must seal repeatedly, so the neck finish is checked for consistency. Dark glass and cellar storage protect the wine through long maturation.

Blow-and-blow forming creates the body and the specialized neck, including the bulb where required. Annealing relieves stress in the heavier glass, and the finish — whether plain bore or bulb — is gauged for cork fit.
