Often, specialty glasses have a unique story behind them. My first true specialty glass was a Kwak glass, see illustration. This glass is a perfect example of specialty glasses because of its unique shape and accessory not to mention a great origin story. I won’t go into the story here but you will be able to find the story with a quick internet search.
Finding the correct beer for these glasses shouldn’t be too hard. The glasses usually have the appropriate beer or brewery name on them and often they are sold as gift packs that contain the glass and a few beers as well. As with any glass, you can drink any beer you want to out of these glasses and you may want to as the appropriate beer may be cost prohibitive to drink on a regular basis.
