A good glass in the cupboard is enough. So do we need a separate glass for each type of wine? "Not at all. A good all-round glass will do, too: it should be thin-walled and lie lightly on the lip so that it causes little discomfort, and it should also be bulbous and tapered at the top."
"The ONE for ALL glass for all wines, sparkling wine and champagne also makes life easier. Contrary to the belief that different glasses should be used for different types of wine, Peter Steger developed a professional glass in which all types of wine can be presented perfectly. This objective follows a practical logic: If it is not possible to achieve the optimum with so many special glasses, one should try to come as close as possible with one glass for all types of wine.The professional sommelier's One for ALL glass brings the positives characteristics, as well as the wine faults."
