What is lemon-lime soda?

Lemon-lime soda is a clear, carbonated soft drink with a citrus flavor that blends lemon and lime. It is sold in regular and zero-sugar versions and is also used as a mixer. Well-known brands include 7UP and Sprite; many stores sell their own.

A US 7UP listing shows these ingredients: filtered carbonated water, high fructose corn syrup, citric acid, potassium citrate, natural flavors and calcium disodium EDTA (to protect flavor). Some products use sugar instead of corn syrup. A Sprite listing shows carbonated water, high fructose corn syrup, citric acid, natural flavors, sodium citrate and sodium benzoate.

How is it made?

In general, soft drinks are made by dissolving sweetener, acid and flavors into a syrup, mixing it with chilled, treated water and adding carbon dioxide under pressure, then filling and sealing cans or bottles. This is the general process, and exact methods are proprietary. It is not a home recipe of lemon juice and sugar, although a homemade version of lemon juice, lime juice, sugar and sparkling water is easy.

How much sugar does it contain?

A product page for 7UP gives about 10.6 g sugar per 100 ml, which scales to about 53 g in a 500 ml bottle. Zero-sugar versions use other sweeteners. Check the label, as amounts vary by brand and country.

Is it caffeine free?

Many lemon-lime sodas are sold as caffeine free. The ingredient lists above do not include caffeine, but check the pack. This is general information.
