A Retailer's 'Plume' Claim Lights Up the Community's Mold Debate

A screenshot circulating on r/cigars this week captured a major online retailer's social media account suggesting that white dust on cigars may be harmless plume. The community's reaction was swift and nearly unanimous: plume is a myth, white dust is mold, and the claim reads like an attempt to move questionable stock. Retail employees in the thread corroborated the skepticism. The exchange matters beyond one thread. The plume-versus-mold question has been settled science in enthusiast circles for years, and when a large seller appears to resurrect the myth, it erodes trust in exactly the retailers newer smokers rely on. It is also a useful consumer reminder: white crystalline or dusty growth on a cigar should be treated as mold, full stop, and any humidor holding affected stock needs a wipe-down.
