Men—No more than 2 standard drinks in the first hour and 1 standard drink each hour after that. Women—No more than 1 standard drink each hour.
The Standard 1-Hour per Drink Rule
Usually, you are safe to use the one-hour per drink rule. So, if you have two glasses of wine, you should wait two hours before driving. When you do an hour per drink, your body has time to overcome the other factors listed above, and hopefully, you have a safe enough BAC to drive.
As a general guide, to stay below the open licence limit of 0.05% BAC: Males can have a maximum of two standard drinks in the first hour, and one standard drink each hour after that; Females can have a maximum of one standard drink in the first hour, and one standard drink each hour after that.
On average it takes at least one hour for your body to clear one small alcoholic drink. For some people it can take longer. That is, at least one hour to clear a middy of beer, or a small (100ml) glass of wine, or a standard nip of spirits. There is no way to speed up the rate your body breaks down alcohol.
Experts say a a good maximum amount of wine for women would be a 5 oz glass of wine, and for men two 5 oz glasses of wine, no more than several times a week. Experts strongly advise women against having more than 3 drinks of wine per day, and for men, 4 drinks of wine per day.
A large glass of wine takes about 3 hours to completely metabolize, whereas some drinks can take as long as 6. Another thing to consider is how long alcohol use (wine or otherwise) can be detected. Consumption can be noticeable for up to 12-24 in breath/saliva or urine, and up to 90 days in hair particles.
Generally speaking, it takes approximately one hour for every unit of alcohol to leave your bloodstream. This is dependent upon your age, weight, gender, genetic factors. This means that a 14% bottle of red, white or rose wine, which is 10.5 units will take around 10.5 hours to wear off.
A small shot of liquor: 1 hour. A pint of beer: 2 hours. A large glass of wine: 3 hours.
How Long Will It Take for Alcohol to Leave Your Body? The body generally processes approximately one standard drink per hour. If you have 5 standard drinks, it will take 5 hours for your body to process the alcohol.
allow at least one hour for your body to process each standard drink. So, for example, if you've had five full strength pots of beers or four glasses of wine, you'd need to wait at least six hours before thinking about getting behind the wheel.
Even small amounts of alcohol can affect your ability to drive, and there is no fool-proof way to drink and stay within the limit. The advice from the police is clear: avoid alcohol altogether if you plan to drive.
Drink driving is a factor in about one in every seven crashes in NSW where someone is killed so if you are wondering about how much alcohol you can drink and still be safe to drive the simple and safe answer is, zero.
It's worrying that 1 in 20 (5%) think it's safe to drink 4 alcoholic drinks and drive. But as a general rule, 2 pints of regular-strength lager or 2 small glasses of wine could put you over the limit. This equates to roughly 4.5 units of alcohol.

Not drinking alcohol is the safest option for breastfeeding mothers. Generally, moderate alcohol consumption by a breastfeeding mother (up to 1 standard drink per day) is not known to be harmful to the infant, especially if the mother waits at least 2 hours after a single drink before nursing.
5–7 days in fridge with a cork Most light white and rosé wines will be drinkable for up to a week when stored in your refrigerator. You'll notice the taste will change subtly after the first day, as the wine oxidizes. The overall fruit character of the wine will often diminish, becoming less vibrant.
Average amount of hours to process
The alcohol from one bottle of wine would take 11 hours from when someone has stopped drinking to leave the bloodstream before it is safe to drive.
Excessive drinking includes: Binge drinking: For women, binge drinking is 4 or more drinks consumed on one occasion (one occasion = 2-3 hours). For men, binge drinking is 5 or more drinks consumed on one occasion.
Wine: The average glass of wine can take 3 hours to leave your system, half of your favourite bottle can stay in your system for 4.5 hours, and the average bottle can take 9 whole hours to leave your body.
The liver metabolizes alcohol at a very constant rate, approximately one drink per hour. If there is excessive alcohol in the blood, the liver cannot speed up the detoxification process. The unmetabolized alcohol just continues to circulate in the bloodstream.
As a rough guide, it's around three hours if you drink one large glass of wine (250ml/three units), about two hours to break down a weak pint of beer, cider or lager (3.6% - few drinks are this weak any more), or three hours to break down higher-strength lager, beer or cider (5.2%).
Essentially, the one drink per hour rule means that as long as someone only consumes 1¼ ounces of hard liquor, one beer, or one glass of wine and no more over the course of an hour, then they are safe to drive.
Drinks per hour rule
The general rule of thumb is that 2 standard drinks in the first hour will raise your BAC to 0.05%, and 1 standard per hour thereafter will maintain that level. To do a quick calculation of whether you are over 0.05% BAC, simply take the number of hours since your first drink and add 1 to it.
