How to Brew Beer with Your Mr. Beer Kit

Before brewing, assemble your spigot and check your keg for leaks.

• Place the washer on the spigot with the beveled side facing the outside of the keg
• Insert the spigot through the hole in the keg
• Screw the nut onto the spigot from inside the keg
• Hand tighten gently — do not over tighten
• Fill the keg completely with water and let it sit for 15–30 minutes to check for leaks

Sanitizing is the key to great-tasting beer — and it’s quick and easy.

• Fill your keg with warm water to line 1
• Add half the cleanser packet and stir until dissolved
• Save the remaining half of the cleanser packet for bottling day
• Close the lid and swirl to coat all interior surfaces, including the underside of the lid
• Let sit for at least 2 minutes, then swirl again
• Run solution through the spigot briefly
• Pour the remaining solution into a bowl and place your spoon, can opener, and measuring cup inside
• Do not rinse or dry your keg or utensils

This is where your beer comes to life. You’ll make the wort, add yeast, and let fermentation begin.

• Remove the yeast packet from under the lid of the extract can
• Place the unopened extract can in hot tap water for about 10 minutes
• Add 4 cups of water to a 4-quart or larger pot
• If Booster is included, stir it into the water until dissolved
• Bring the water to a boil, then remove from heat
• Open the extract can from the bottom and stir the extract into the pot until fully dissolved
• Fill the keg with cold water to line 1
• Pour the wort into the keg, then top off to line 2 with more cold water
• Mix vigorously with your sanitized spoon or whisk
• Sprinkle the yeast packet into the keg and close the lid — do not stir
• Store the keg in a cool, dark place between 68–78°F, ideally 70–72°F
• Let it ferment for 10–14 days

After fermentation, your beer is ready to bottle when it tastes like flat beer — not sweet.

• After 10 days, pour a small sample from the spigot into a clean glass
• If it tastes like flat beer, it is ready to bottle
• If it tastes sweet, let it ferment a few more days and test again
• Do not leave beer in the fermenter longer than 21 days total
• Clean and sanitize your bottles and bottling equipment using the remaining cleanser
• Do not rinse after sanitizing
• Add carbonation drops or sugar to each bottle
• Fill bottles at an angle with the spigot nozzle inside the bottle to reduce foaming
• Fill to about 1 inch from the top
• Cap tightly and check the seal on each bottle

This is where your beer develops carbonation and flavor.

• Store bottles upright at room temperature
• Keep bottles out of direct sunlight
• Keep bottles between 70–78°F for best carbonation
• Let sit for at least 14 days
• Refrigerate for 48 hours before drinking

Your beer is bottled — now clean your equipment so your next batch tastes just as good.

• Remove and disassemble the spigot assembly from the keg
• Wash all parts with warm water using Oxygen Brewery Wash or clear, unscented liquid soap
• Use a clean, soft cloth
• Rinse everything thoroughly with warm water
• Do not use scouring pads, wire brushes, abrasive sponges, or abrasive cleaners
• Clean and rinse bottles immediately after use
