A mini bottle of wine, also known as a demi or half bottle, typically contains 375ml of wine. This is exactly half the volume of a standard bottle of wine, which is typically 750ml. To put it into perspective, a mini bottle of wine is a little more than 12.5 fluid ounces.
Now, when it comes to determining how many glasses of wine you can get from a mini bottle, it depends on the size of the wine glass and the pour size. The standard pour size for a glass of wine is around 5 ounces (150ml). So, if we divide the volume of a mini bottle (375ml) by the standard pour size (5 ounces), we can estimate that you'll get about 2.5 glasses of wine from a mini bottle.
Of course, this estimation assumes that you are pouring the wine into standard-sized wine glasses. If you are using smaller glasses, you may be able to get more than 2.5 glasses from a mini bottle. On the other hand, if you are using larger wine glasses, you may get slightly less than 2.5 glasses.
It's important to note that the number of glasses you can get from a mini bottle also depends on personal preference and how much wine you like to pour in each glass. Some people prefer a generous pour, while others prefer a more moderate pour. So, while 2.5 glasses is a rough estimate, individual pouring habits may vary.
In my experience as a sommelier, I've found that mini bottles can be quite convenient in certain situations. They are great for solo drinkers who don't want to open a full bottle and risk wasting the remaining wine. Mini bottles are also handy for picnics, outdoor events, or when you want to enjoy a variety of wines without committing to a full bottle.
A mini bottle of wine, which contains 375ml or a little more than 12.5 fluid ounces, will typically yield about 2.5 glasses of wine at the standard 5-ounce pour. However, the number of glasses may vary depending on the size of the wine glasses and personal pouring preferences.
