This isn’t a safe assumption to make about crystal in general — it depends on the specific range.
Machine-made crystal is often dishwasher-safe
Riedel’s Performance and Cabernet decanters, both machine-made rather than hand-blown, are explicitly marketed as dishwasher-safe — a real feature of that manufacturing process.
Traditional hand-blown crystal generally isn’t
More traditional, hand-blown lead crystal decanters are typically more fragile and often recommended for hand-washing only — check the specific piece’s own care instructions rather than assuming based on material alone.
Narrow necks are hard to clean either way
Even a dishwasher-safe decanter’s narrow neck can trap residue a dishwasher’s spray doesn’t fully reach — cleaning beads, swirled with water, remain useful even for dishwasher-safe pieces.
Check the specific listing, not just the brand
Even within one brand’s range, dishwasher-safety can vary between collections — Riedel’s own Performance and Cabernet ranges are stated as dishwasher-safe, but this doesn’t automatically extend to every Riedel product.
What we would not do
Assume any crystal decanter is dishwasher-safe because a similar-looking one is. Check the specific range’s own stated care instructions before risking a piece that isn’t rated for it.
