All of the care put into providing the perfect beer might end up wasted unless operators take extra precautions to serve beer in clean glasses. After all, a beer's appearance, taste, and aroma are all affected by any residue remaining on the glass -- and this will impact a bar's bottom line.
Ever order a beer, have that beer arrive in front of you, and see grease marks all over the side? What about a glass of wine? Ever order a pre-meal Chardonnay and see lipstick marks on the glass? Not pleasant, huh?
Beer is profit. In fact, in many restaurants and foodservice operations, the bar and beverage program is the most profitable aspect of the entire business. But what does this have to do with clean glasses? It all comes down to foam, waste, and the quality of beer.
