Why is Iced Coffee Level 2 on average?
Plain iced coffee or cold brew is one of the simplest beverages: coffee beans steeped in cold water for 12-24 hours, then filtered. The entire process is extraction, with no additives needed. Commercial bottled iced coffee is often a different product. Sweetened bottled coffee drinks can list milk, sugar, coffee extract instead of brewed coffee, natural and artificial flavors, and stabilizers such as carrageenan or mono/diglycerides. Even simpler bottled cold brews may add sugar or natural flavors. The sweetened, flavored varieties are made for shelf stability and consistent taste across a supply chain that homemade iced coffee never encounters. In our analysis, iced coffee products average a Processing Score of 3.6, which is Level 2.

Is Starbucks bottled iced coffee ultra-processed?
Bottled Frappuccino drinks combine coffee with milk, sugar, and added flavor or stabilizers, which makes them more processed than plain brewed coffee over ice. Check the bottle's ingredient list; each product page shows its own score.
What is the least processed iced coffee I can buy?
