Glassware Part 2 - The Non-essentials:

• Margarita Glasses: Unless you really love margaritas, and serve them at every party, you usually can get away with serving them in another kind of glass; especially if you’re serving them frozen. (various sizes)
• Punch Bowl & Cups set: The cool things about punchbowl sets are that they’re often sold pretty cheap, and there really isn’t too large an aesthetic difference between one made of plastic, glass or crystal, so going cheap on these isn’t really a big deal.
• Parfait glasses: Used specifically for frozen and juice drinks. But, as I said, you can get away with using pint glasses for those, so this one isn’t a truly essential item. (12 – 16 oz.)
• Red/White Wine Glasses: Yes, there is a difference between the two: White wine glasses are longer, more slender, and taller (like fatter champagne flutes with shorter stems), whereas Red Wine glasses are shorter and wider, so that the red wine is given a chance to “breathe” before you drink it. (4 – 8 oz.)
• Cordial glasses: Small, fancy glasses used to sip cordials (also known as liqueurs.) There are also slightly larger short stemmed, fancy glasses used for whiskey sours and other sweet drinks. You really don’t need either; in fact, they’re so not useful, that I lumped both into the same bullet point. (1 – 4oz.)
• Collins Glasses: These look like rocks glasses and pint glasses had a kid. They’re somewhere in between the sizes of both. Honestly, though, you really don’t need these; in fact, other than a Tom Collins, I can’t even immediately think of what kind of drink you’d serve in these, and I’m an expert, so you know they’re useless. (12 oz.)
