Riedel has really expanded its products line (and production capacity through acquisitions) in the past few years and also their distribution - you'll see them in many retail channels now (used to include Macy's). There are now various lines that don't have any lead and are now dishwasher safe ((lead) crystal will get etched) and it'd appear Ouverture is one of those lines.
Research what you like and whether it fits your needs. I think only the expensive Sommelier line is hand-made/blown in Austria - the lower lines are machine-made in Germany. That said as a fan of the original Vinum line.
