cold brew french press

Common materials include double-wall food-grade 304 stainless steel, borosilicate glass carafes, and lightweight plastic/Tritan used in smaller press models.

Larger French presses typically use metal fine-mesh or multi-plate stainless steel filtration systems. Some compact press devices use paper filters or note that no separate filter is required.

Many 34 oz (1 L) presses list a 4-cup capacity with cup sizes around 8–8.5 oz. Some smaller press models list capacities up to 8 cups, reflecting smaller per-cup volumes.

Many listings describe glass and steel 1 L presses as compact enough for home, office, or camping. Smaller press designs emphasize travel-ready, compact, lightweight construction.

Several full-size models use double-wall vacuum insulation made from food-grade 304 stainless steel. Listings state the vacuum insulation helps keep coffee hot while the exterior remains cool to the touch.
