Use the verb tipple when you want to show that someone drinks moderately but regularly. During Prohibition in the 1920s it was illegal to tipple but today you can tipple almost anywhere — as long as you are 21.
As a noun, a tipple is an alcoholic drink. Your usual tipple may be a glass of wine with dinner, but at a summer barbecue your tipple may be beer. From tipple we also get the noun tippler — a person who drinks regularly but moderately. Experts aren't sure where the word tipple comes from, but it may be from a Norwegian word, tipla, which means to drink slowly.
