Overview
Riedel shapes this stemless tumbler specifically for Cabernet and Merlot, selling it in a set of four at a generous 21.16 ounces each.
Riedel built the O line to survive outside a formal table setting, the description calls out the dishwasher, picnic basket and minibar as intended homes for it. The bowl still follows Riedel's varietal-specific stemware shaping, just without a stem underneath.
- Set of 4 tumblers
- 21.16 oz capacity
- 3.74 x 3.74 x 4.76 in
- Shaped for Cabernet and Merlot
Who it's for
Suited to Cabernet and Merlot drinkers who want a stemless glass without giving up the bowl shape Riedel designs for that wine style. Less suited to anyone drinking mostly whites or sparkling, since this bowl is cut for bigger reds.
Pros and cons
- Varietal-specific bowl shape for Cabernet and Merlot
- Generous 21.16-ounce capacity per glass
- Dishwasher safe across the whole set
- Portable stemless design for casual use
- Not shaped for white or sparkling wine
- No stem for those who prefer one
Performance notes
The bowl geometry is what Riedel is actually selling here, a wider bowl lets a full-bodied red open up more than a straight-sided tumbler would. Riedel states its whole range is dishwasher safe, so there is no special hand-washing routine to maintain.
