Wine Pour Guide

Standard pours from a 750ml bottle:

Standard Pour (5oz)5 Glasses
Tasting Pour (2oz)12 Glasses
Bordeaux Pour (4oz)6 Glasses

The Large Formats

Most large bottle formats are named after biblical kings. Aging wine in larger bottles is often preferred by collectors because there is less oxygen relative to the volume of liquid, leading to a slower, more graceful aging process.

The Architecture of Wine Bottles

A wine bottle is more than just a glass vessel; it is a standardized unit of measure that has evolved over centuries. While the 750ml bottle is the global standard today, the world of fine wine and Champagne utilizes various formats, each with its own traditional name and use case.

Standard vs. Large Formats

Large format bottles, such as the **Magnum (1.5L)** or the **Jeroboam (3L)**, are prized by collectors and event planners. Not only do they make a visual statement at a dinner party, but they also reduce the surface area of wine exposed to oxygen under the cork. This "ullage" ratio means a Magnum of vintage wine will often taste fresher many years later than a standard bottle of the same vintage.

Naming the Kings

The names of large format bottles are rooted in history and tradition. Names like **Nebuchadnezzar** (15 liters or 20 standard bottles) and **Balthazar** (12 liters) reference historical kings and figures. While rare, these bottles are still produced today by high-end estates for significant auctions and celebrity celebrations.
