Alto Astral by Byredo opens with aldehydes and coconut water, a fizzy, faintly milky freshness. From there it moves straight into a warm, woody base of amber, cashmeran and sandalwood, smooth rather than sweet. New for 2025, it is worn by men and women alike, anyone who wants a fresh opening that settles into something calmer. Voters wear it across summer and spring, from day into evening and night, which makes it flexible rather than tied to one moment. The longevity vote leans long-lasting. Most wearers call its sillage moderate, keeping it fairly close rather than loud. A 10ml decant is enough to live with it through a season and decide if it earns a place on your shelf.

The community verdict
Aldehydes and coconut water give Alto Astral a sparkling start before amber, cashmeran and sandalwood take over. The largest group finds it long-lasting, and most report moderate projection. It suits summer days, with spring and evenings also working; it draws compliments.

The house
More from Byredo
Byredo was founded in Stockholm in 2006 by Ben Gorham, and its perfumes have a spare, Scandinavian clarity. Musk and sandalwood sit under most of them, with violet, blackcurrant and pink pepper for colour and aldehydes for a clean, airy lift. Bal d'Afrique Absolu and the original Bal d'Afrique lead the way, the second a bright mix of citrus, flowers and woods. Gypsy Water is fresh and aromatic over soft woods. Blanche is crisp and pale, all aldehydes, flowers and musk. Mojave Ghost sits between them, woody and floral with a musky finish.
