How can I hide the alcohol smell?

Long story short my parents don’t allow me to drink (even though I’m 25) because they are in a religion that doesn’t allow drinking. Whenever I come home late at night to tell my mom that I’m home she like sniffs me to smell if I drank. How can I mask the smell really well so I don’t get the stank look in the morning? By the way, I don’t live with my parents but there is an event in my hometown in which I’m staying with them.
