Carbonated beverages like soda or sparkling water tend to speed up the absorption of alcohol because the carbonation helps to open up the stomach lining and allows the alcohol to enter the bloodstream more quickly.
Alcohol is more readily absorbed on an empty stomach, than the slow absorption on a full stomach.
The primary absorption site for digestible carbohydrates is the small intestine. Carbohydrates are broken down into simpler sugars during digestion and then absorbed through the lining of the small intestine into the bloodstream to be used for energy by the body.
Stomach and Small Intestine
It is the main site of water re-absorption.
Alcohol is primarily absorbed into the bloodstream through the stomach and small intestine. Once consumed, it passes quickly through the stomach lining into the bloodstream, with the small intestine being the main site for absorption due to its larger surface area. This rapid absorption is why alcohol can have immediate effects on the body.

A high fat meal will slow the absorption of alcohol.
A full stomach reduces the rate of alcohol absorption.
Eating a meal high in fats and proteins before drinking alcohol can slow down its absorption. Additionally, consuming alcohol at a slower pace, staying hydrated, and avoiding carbonated drinks can also help slow down the absorption of alcohol in the body.

These do not speed up the absorption of alcohol. The typical body processes alcohol at the rate of 1 unit per hour. There is no quick fix for absorption. Although I'm not sure about the effect of fruit punch on alcohol absorption, carbonated beverages DO increase alcohol absorption, I think the previous answer is confusing alcohol absorption with alcohol metabolism. In particular the increased temperature of your body causes the CO2 gas to come out of solution and speeds up alcohol assimilation into the blood stream. Assuming the same amount of alcohol as a non-carbonated beverage, the increased speed of assimilation will increase the rate at which alcohol can go to your body's tissues (with the exception of fat), ALTHOUGH this will not change the rate of your liver's alcohol metabolism.
The reason why intoxicated people drink coffee is not to slow the absorption of alcohol into the body, but to use caffeine as a stimulant, to counteract the depressant effect of alcohol. One drug fights against the other. But no, coffee does not slow the rate of alcohol absorption into the bloodstream.
