An expert claims it is due to the way alcoholic strengths are measured, and in particular, how this translates to the number of units in your favourite tipple. In fact, over the course of a three-hour drinking session, the amount of alcohol in your system when drinking the five per cent beer is double the amount left over during the same period drinking the lower strength version. Equally, some spirit drinkers can have numerous measures before feeling the effects, while the same person can feel tipsy after just one pint of beer.
This is despite the fact the spirit is typically around 40 per cent strength, compared to a beer's relatively meagre 5 per cent. According to beer expert Joe Stange from Draft magazine , the reason can be explained using simple maths. In the UK, a unit is the measure of the amount of alcohol in a drink.
One UK unit is 10ml 8g of pure alcohol and a typical pint of ale contains one or two units, while a glass of wine can contain anything from around one and a half to three units, depending on the size of the glass and its strength. In the UK, a unit is the measure of the amount of alcohol in a drink, and one unit is 10ml 8g of pure alcohol. In the US, units are measured as 'standard drinks'. After two hours, this increases to 0. Many drinks now show the strength, measured as 'alcohol by volume' or ABV, on the label alongside the number of units.
Alternatively, people can calculate the number of units in their drink by multiplying the amount in millilitres ml by the strength ABV and dividing the result by 1,, or by using a unit calculator. But as a rough guide, one unit of alcohol is equal to half a pint of 4 per cent lager or beer, 25ml of a 40 per cent spirit, a standard 50ml pub measure of 20 per cent of sherry or port. A small glass ml of 12 per cent wine contains typically one and a half units. Examples are shown.
One UK unit is 10ml 8g of pure alcohol and a typical pint of ale contains one or two units, while a glass of wine can contain anything from around one and a half to three units, depending on the size of the glass and the strength of the wine.
At its very simplest, if one bottle was drunk each hour for three hours, the excess alcohol would be 0. It has a higher number of units given the size difference of the bottle. After one hour there would be 0. A measure of This is a simplified version, however. In reality, the body would start to process the excess units during the hour in which the drinker was finishing their next beverage - unless of course they downed the drink at the start of each hour.
In the US, however, units are measured as 'standard drinks'. One 'standard drink' contains around 14 grams of pure alcohol and examples include 12 ounces of regular beer, typically five per cent, 5 ounces of 12 per cent wine, or 1. However, the calculations are simplified. In reality, the body would start to process the excess units during the hour unless the drink was downed.
According to UK charity Drink Aware, it takes an average adult around an hour to process a unit of alcohol, so that there's none left in their bloodstream. Using Mr Stange's calculations, this means that a 4 per cent beer in a ounce ml bottle contains 1.
If one bottle is consumed every hour, after the first 60 minutes the average adult would have processed the unit and have 0. After two hours, this in theory increases to 0. Meanwhile, the same sized bottle of five per cent beer contains 1. This leaves 0. When it comes to spirits, a single measure is typically one unit meaning that if drinks are drunk one hour apart, the alcohol is typically processed with no excess.
In reality, the body would start to process the excess 0. And as Mr Stange points out, people are rarely that regimented to consume one drink an hour and his calculations are used purely as a guide to highlight the issue.

You can easily lose control of what you do or say and may make risky decisions, thinking you're invulnerable.
Bear in mind that some people, including women, young people and those with smaller builds, may experience the effects after drinking smaller amounts of alcohol. If you find you have become tolerant to the effects of alcohol, you may be at risk of health problems. In that case, consider whether it's time to cut back on your drinking or you need to seek help.
