I run the two beer festivals in Kennett Square and am trying to research this style "glass' especially for our Connoisseur session and Winterfest. We cannot use real glassware. I've pretty much struck out on something that fits my eye. I'm thinking the Troegs sampler glasses. Help!!!
Something like this? http://www.alibaba.com/product-deta...0212402591.html?spm=a2700.7724857.35.1.Xh1m6L
As a follow on to the suggestion made by @dennis3951 , I've used these plastic wine glasses: http://www.amazon.com/5-5-Ounce-Wine-Glass-Stemware/dp/B00CJFUQZS for an occasional party that was for about 40-60 people. Different scale than your events but still worked well--easy to store, easy to assemble, easy to get to a recycling bin if needed and easily replaced if dropped and/or damaged. Not as fancy as a plastic snifter, but reasonably priced.
Your best bet then may be a trip into Philly. IIRC there are/were a few restaurant supply places on about 2nd street not all that far north of the underground stop and so easy walking distance. (But check to see they are still there first as its been a while since I saw them.) Working through one of them you might find a supplier for a large number of something useable and useful that can also have a logo.
This site might suit your purposes. Order minimums appears to be much less than 2400. This glass specifically.
Check out Howw.com. They are a branding company that only offers acrylic/styrene. I've outsourced to them several times with great success.
Would be quite a bit cheaper to buy blanks and get sheets of stickers and apply yourself. Depending on how many you're talking about, may be easier too. Even if it looked "cheap" I doubt anyone is going to "save" a plastic wine glass even with a logo as a "memento."
