We study grapes and wine, but wine is alcohol :) This is presentation for discussion with our students about this - Is the use of wine useful? They have done calculations how many hours are needed per person to absorb a drink. This method is not very accurate because everything depends on the human body / the Chinese can not drink, for example, because they do not have an enzym for its degradation /

1. Is the use of
wine useful?

2. The wine consumption is healthy, is it?

 Wine is healthy but without abusing.
 Everyone should have drinking culture.
 This means to drink for amusement and not in order to get
drunk.
 Enjoying wine means to drink it with food, slowly, taking small
sips so that one can feel the taste and aroma qualities as much
as possible.
 Wine culture includes the ability to combine wine with the
suitable food. Wine improves digestion.
 Drinking fast and on shots is harmful and it practically means
wasting wine!
 Responsible wine drinking (up to 1-2 glasses per day,
depending on your body) is healthy.

3. How much is useful?

4. What is Standard drink
 A ‘standard drink’ is a notional drink that contains a
specified amount of pure alcohol (ethanol) which one
handles for 1 hour;
 A ‘standard drink’ contains 8-16 grams of pure
alcohol in countries of Europe. It is important to
note that drink serving sizes are often more than one
standard drink. There are no common glass sizes
used in Bulgaria.

5. Reduce your risk about drinks
?
Mathematics drinking:
How to calculate how many standard drinks have a
glass of wine if we know its volume and concentration
of alcohol.
The density of alcohol is 789.24 grams / liter.

6. Reduce your risk about drinks
?
Example : .
If you drinks 0, 150 liter wine, 12%
concentration of alcohol :
Number of hours =
0,15∗0,12∗789,24
10
=
14,20
10
≈ 1,4
Your body will be able to process this alcohol for 1 hour and
24 minutes.

7. Reduce your risk about drinks
Example :
If you drink 1 bottle wine /1 liter/ , 11% concentration of
alcohol:
Number of hours =
1 ∗0,11 ∗789,24
10
=
86.81
10
≈ 8,7
Your body will be able to process this alcohol for
8 hours 42 min.

8. Reduce your risk about drinks
Example :
If you drinks 0,500 liter wine 13% concentration of
alcohol:
Number of hours =
0,5 ∗0,13 ∗789,24
10
=
51,30
10
≈ 5
Your body will be able to process this alcohol for 5 hours.

9. Reduce your risk about drinks
Example :
If you drink hard alcohol (concentrate)
100 гр. rakiya (Bulgarian traditional drink) 42%
:
Number of hours =
0,1 ∗0,42 ∗789,24
10
=
33,14
10
≈ 3,3
Your body will be able to process this alcohol for 3
hours and 20 min.

11. Tips to reduce the risk to your
health when drinking
• Set limits for yourself and stick to them;
