The questions independent drinks founders ask most — answered. Distilled from years of community knowledge so the good stuff never disappears in the feed again.
What preservatives, pasteurisation methods and shelf-life standards do non-alcoholic RTD beverages require?
Non-alcoholic RTD beverages typically require specific preservation techniques to achieve extended shelf life. Members report achieving 3-year unopened shelf life with 12-month open ambient life on their products. **Preservation methods:** - **Hot pack pasteurisation** — the standard approach, performed during packing - **Post-pack pasteurisation** — an alternative thermal processing method - **Acids and sorbate** — chemical preservatives commonly used - **Avoid corks** — cork closures are not recommended for non-alc RTDs **Typical shelf-life benchmarks:** - Unopened ambient: 3 years (achieved by members) - Once opened: 12 months ambient (member experience) - Bag-in-box (5L): 9–12 months unopened; 4–6 months once opened **Key caveat:** Sodas like Sprite and Coke achieve their extended ambient shelf life through a combination of high acid content, sorbates, and pasteurisation. Unlike spirits and some low-ABV RTDs which require refrigeration, properly preserved non-alc beverages can remain shelf-stable. Members note that taste quality may degrade over very long storage periods even if the product remains safe.
What colour additives and preservation methods should we use for display and event samples?
For display samples at events, members use food colouring to match product appearance and preserve stability. **Food colouring** — cheap and effective for matching rum and pink gin colours in display minis; coordinate the shade with your bottler to replicate your actual product. **E150a caramel** — recommended as a standard colour solution, particularly for steeps or macerates; discuss feasibility with your bottler as each line differs. **Potassium sorbate and citric acid** — add both to prevent mould growth and extend sample shelf-life at events. Members suggest having a direct conversation with your bottler about what's practical for your specific production setup, as preservation needs vary by format (mini bottles vs cans).
