Whether you are serving Q at a restaurant or your house, the ideal way to present it to your guest is what we call a “spectacular serve.”
Put ice and your spirit of choice into a highball glass and garnish it. Good ice matters – use nice, solid cubes. They won’t melt as quickly.
Bring the glass and the bottle of Q to your guest. A tray is nice, but not necessary. Either way, present the drink like you’re presenting something special. You are.
Open the bottle in front of your guest and pause while it “pops.” Slowly pour into the glass until ¾ full. To maintain carbonation, tilt the glass 20° as you pour the liquid down the side.
Place the glass and the bottle down in front of your guest and encourage them to top off the drink as desired. Leave the bottle cap alongside the glass.
