What are effective alternatives to brown glass for UV protection of light-sensitive spirits like saké?

UV protective coatings and sleeves exist as alternatives to colored glass, though they are less effective and more expensive. **UV protective spray coating** can be applied directly to clear glass and remains largely transparent after application, though it may have a slight haze depending on application quality. **UV protective sleeves** are also available but similarly add some haze to the glass and are not as reliable as brown glass for UV protection. Members noted these solutions work best for combined color and flavor stability needs (such as with saké) but come with trade-offs in terms of cost, transparency, and protective efficacy compared to traditional brown or dark glass.
