Non alcoholic drinks are interesting.
People vary on their choices depending on the situation they are in,
For example, sometimes in an important party people still like to look as though they are drinking and enjoying themselves but don't want to look a fool the next day and will ask for a cocktail that looks like a cocktail but with no alcohol, i.e a plain tonic with a slice of lime or a virgin mojito etc.
Women who are pregnant, I find, still like to think that they are drinking and so will ask for a drink which allows them to feel they are socialising. The glassware is important for this and many women ask for virgin mimosas or bellinis or even just lemonade in a champagne flute. I findd women on dates ask for this kind of drink as well.
People on holiday relaxing in the sun tend to be a bit more adventurous and like the physical appearance in addition to the thirst quenching properties of the cocktail. Any kind of fruit juice or combination of flavours presented in a stylish glass will usually keep the customer happy.
Drivers again want to feel they are joining in with the festivities and celebrations and are sometimes left short handed in terms of drinks offered to them at parties or bars. The only non alcoholic beer I would ever reccomend is Erdinger non-alcoholic. It tastes exactly the same as a premium European lager and is even used by some athletes for it's nutritional values.
Other specific low – alcohol at around 2.5% to 4% are great drinks like Stiegl Radler a grapefruit beer from Austria which is great in the sun and also Moscato an elegant and refreshingly crisp sparkling wine from Italy.
Lager shandies and white wine spritzers are still the drinks of choice for people who still want to drink but want to make sure they last the evening.
I hope this helps
