To start, the glassware is all noticeably thinner. At first they seem a bit fragile, but after some handling you'll realize they are actually quite sturdy. In addition to being thin, the glassware is noticeably all very unique. While the Tulip, Weizen and Lager glasses are similar to other maintstream ones, there are subtle differences in the shape that seem deliberate and calculated. The best part about the tasting was having a 'control' glass, your standard shaker pint, to do a side by side of each beer we poured. The biggest standout to me was the lager glass. We poured a Sly Fox Oktoberfest in both the shaker pint and the Spiegelau lager glass, the resulting beer experience was very different. A lot of folks overlook lagers for not being flavorful, mostly because they aren't bitter or hoppy. But, when using the proper glassware, the delicate malty flavors and aromas really popped out at you.
This event was also my second time using the now infamous IPA glass developed by Spiegelau, Dogfish and Sierra Nevada. While I do think a tulip is mostly suitable for the style, there's no doubt this glass provides a little something extra in the aroma department for hoppier styles.
Here's a link to the kit we received for attending. As you can see, the $25 we paid for the event, glassware and 4 beers was really a bargain.
