Meth or merlot?

A Chicago man on home monitoring for possessing what police said were meth-making materials, who wore a meth-related t-shirt in his booking photo, and who was found again with alleged meth-related paraphernalia was only making wine, his mom said.

“He had winemaking equipment,” Jan Kowalski told The Chicago Tribune.

Still, Daniel Kowalski, 23, pleaded guilty Friday to two drug possession charges and was sentenced to two years of probation and 30 hours of community service.

Daniel, who lives in Chicago suburb La Grange, was already on home monitoring stemming from a July 2013 arrest when cops found meth-related materials in his possession when police again allegedly discovered meth-making components during a February 2014 encounter. Police went to the house after getting a tip that Daniel was manufacturing meth.

Investigators reportedly found glass beakers, burners, chemicals and instructions for making controlled substances, according to The Tribune.

But his mother said they were carboys and pipettes used in winemaking. She said Daniel made two batches of wine.

In his 2014 mug shot, Daniel is pictured wearing a “Los Pollos Hermanos” t-shirt. That fictitious fast food restaurant was a front for a meth kingpin on the popular TV drama “Breaking Bad.”
