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).
