Mr. Beer Root Beer Home Brewing Kit — 2-Gallon Starter Set with Bottles & Yeast, Naturally Carbonated

Mr. Root Beer Home Brewing Kit makes two gallons of naturally carbonated, smooth, old-fashioned root beer in as little as three days with everything needed to start brewing at home.

Whether you want a weekend project with the family or a way to enjoy a creamier, less fizzy soda at home, this kit gives you the starter equipment and ingredients to make two gallons of root beer. The system relies on natural bottle conditioning for carbonation, so finished bottles have a softer bubble and richer mouthfeel than many store-bought sodas. The package contains extract, flavor crystals, yeast, bottles and simple tools—so you can go from unpacking to fermenting in one session.

How long does it take to make drinkable root beer?

From first mix to chilled serving, you can expect about three days for primary conditioning, although flavors develop further if left longer. Room temperature during fermentation affects timing—warmer speeds it up, cooler slows it down. Always follow the included instructions for the best outcome.

• Typical readiness: about 72 hours at moderate room temperature
• Faster carbonation in warmer environments (but avoid overheating)
• Stronger flavor if allowed to age an extra few days

What comes in the box and what will I need afterward?

The kit includes the main consumables and reusable items required to brew two gallons: a bottle of root-beer extract, two packets of flavor crystals, root-beer yeast, a no-rinse cleanser packet, four 1-liter bottles with pressure-release caps and gaskets, a funnel, and an instruction sheet. Refill packs are sold separately when you want to brew again without repurchasing bottles and tools.

• Included: extract, flavor crystals, yeast, cleanser, 4 capped 1L bottles, funnel, instructions
• Not included after first batch: additional extract or crystals (refills available)
• Reusable parts: bottles and funnel; replace caps/gaskets only with Mr. Beer parts

Is it safe and what packaging should I use?

Safety depends on using the kit’s specialized pressure-release caps and gaskets—do not substitute standard PET or glass bottles, which can rupture under natural carbonation pressure. The instruction sheet includes cleaning and handling directions to reduce breakage risk. Use the no-rinse cleanser provided for sanitized results.

• Always use the included Mr. Beer pressure-release caps and gaskets
• Do not brew in standard PET or glass bottles—risk of explosion
• Use the provided no-rinse cleanser for proper sanitation

How does natural carbonation affect taste and texture?

Natural bottle carbonation produces a creamier, less aggressive effervescence than forced-carbonated sodas, which many drinkers perceive as smoother and richer. The two flavor crystal packets let you adjust sweetness and spice notes, while yeast-driven carbonation adds subtle depth. Because carbonation is gentler, root beer flavors remain prominent on the palate.

• Softer bubbles and smoother mouthfeel from natural bottle conditioning
• Flavor crystals allow tweakable sweetness and complexity
• Yeast fermentation contributes mild, rounded taste notes

Who is this for? The Mr. Root Beer Home Brewing Kit is designed for curious home brewers, families looking for a fun kitchen project, and anyone who prefers a creamier, old-fashioned root beer experience. It’s beginner-friendly but produces results that hobbyists will appreciate, and refills make it easy to keep brewing after your first two gallons.
