The drinking age in Wisconsin is 21 and consumption of alcohol by anyone under 21 is illegal with the following exceptions:
Although drivers under 21 account for less than 10% of licensed drivers, they account for 12% of DUI related fatalities in Wisconsin, according to one survey. Because underage drinkers cause a disproportionate number of alcohol-related auto fatalities, the standards are stricter and the penalties may be harsher for those under 21.

Wisconsin is a zero-tolerance state. If a chemical test determines that an under-21 driver has a blood alcohol content (BAC) above 00.00%, the driver can be cited for driving under the influence.
If First Drunk Driving Conviction: imprisonment (no minimum), fine ($150 $300), license suspension (six to nine months)(more information: First Offense DUI in Wisconsin).
If Second Drunk Driving Conviction within 10 Years: imprisonment (Up to 1 year jail) fine ($300 up to $1,000) license suspension (12 to 18 months). (More Information: Second Offense DUI in Wisconsin.).

In addition to driving under the influence, an underage drinker may be charged with any of the following:
Some insurance companies may terminate a policy after an underage DUI (while others refuse to renew). Most companies simply raise the cost of the monthly premium by $100 to $200 (sometimes higher) for a higher risk policy. The raise usually stays in place for three to five years. You’ll also probably need to furnish the DMV with an SR-22 certificate to reinstate a license after suspension (as proof of insurability). Most insurance companies furnish this form to the DMV. Check with your insurer to see if it performs this service.
