1, 1 ML 2 standard bottle (375pm). 
It is a common small-size wine bottle, which has exactly half the capacity of the standard bottle. 
In addition to ordinary red and white wine, it is also common for expensive rotten wine (botrytised wine) to use this size. 
I think 1Accord 2 standard bottle is very suitable for one person or going out for dinner for two. 
2. Standard bottle (750ML). 
International standard size wine bottle, about 4 pounds 5 quarts. 
Whether it is red wine, white wine or sparkling wine, the standard bottle capacity is used. 
Although the sparkling bottle is larger than the average bottle, the glass of the bottle is thicker to support the pressure of the bubble, and the capacity remains at the standard size of 750ml. 
3. Large wine bottle (Magnum). 
The most common large-size wine has a capacity of about two 750ml standard bottles or 1.5L. 
In Australia, more famous wines produce large bottle sizes to facilitate long-term storage by collectors. 
In addition, sparkling wine sometimes uses large bottle size bottles for secondary fermentation, which is generally believed to prolong the best taste life of sparkling wine. 
4. Extra large wine bottle (Double Magnum). 
One bottle is about four 750ml standard bottles or 3 liters of wine.
