Keg cocktails are simply that, what they call: mixes, that you put in kegs and pour directly from it. When you have tap, you pour the drink by means of same type of system, that you use for beer on tap, but instead of mix every glass fresh according to order, everything already ready in the keg, that is connected to the dispenser. Bars already years try to find the ideal mode serve professional cocktails quickly, with permanent quality and effectively at the same time
The clearest advantage here is the pace. When time lacks and prepare beer is not possible, kegged cocktails settle the problem immediately. You do not require to wait fermentation, because your homemade drink already ready use.
How to Make and Serve Cocktails in Kegs
More and more stores jump on that fashion serve not only beer from kegs, chiefly to stand out from the crowd.
Cornelius kegs answer well for that: they are reconditioned old syrup kegs of Pepsi and Coca-Cola. Each stores 5 gallons, so suffice for many rations without risk end early. The lids open easily from up, what simplifies filling and cleaning later.
One such keg carry around 640 units of liquid. If half barrels seem too big for cocktail pours, sixtel kegs bid alternative. Two gallon kegs also deserve attention, they give around 21 rations of 12 units and well operate for cocktails.
Rather than leave drinks in open bowls or big pitchers, kegs seal tight protect against oxygen. So they stay fresh and delicious much more long, than without that.
If you do not have too many days, shake the keg occasionally for everything mingle well. Occasionally add a bit of water if needed, because you do not shake every glass separate and dilution must be additional. Recipes in keg you prepare similarly to cook: you assemble ingredients and taste as you go.
No every recipe adapts perfectly for big amount, but that is normal.
For instance guilt-free margarita: enclose in keg circa 76 units of tequila, later 38 units of lime juice. Add 19 units of agave nectar and 19 units of cold water. For creativity you can plunge fruit syrup.
The screwdriver are even simpler, only shed orange juice and vodka in the keg, and ready. Cocktails with three or less ingredients answer best for that method.
Because of carbonation under 50 psi you carbonate 5 gallon keg in only 5 until 10 minutes. The secret is close the CO2 tank commonly and discharge air by means of the valve up. Other mode: carbonate in 30 psi while around 5 days, shake occasionally, and later shed in glass with salt rim over ice.
5 liter pre-mixed party kegs give around 50 cocktails and come with pull tap, what does everything extremely practical.
