There’s nothing quite like the smooth, creamy taste of a freshly poured pint of Irish stout. That deep, dark color, the rich roasted malt flavor, and the signature foamy head—it’s a thing of beauty. But what if I told you that you could craft your very own Irish stout from the comfort of home?
Brewing beer at home may seem intimidating at first, but with the right ingredients, equipment, and a bit of patience, you can create a traditional Irish stout that rivals anything you’d find at the pub. Whether you’re looking to try homebrewing for the first time or want to add an Irish classic to your repertoire, this guide will take you through the process step by step.
What Is Irish Stout?
Irish stout is a dark, dry beer known for its smooth, roasted flavor and creamy mouthfeel. Unlike other stouts, Irish stout is typically lower in alcohol (around 4-5% ABV) and relies on roasted barley for its signature taste and deep black color. Think of it as the heart and soul of an Irish pub—perfectly balanced between bitterness and a slight coffee-like sweetness.
Essential Equipment for Homebrewing
Before we dive into the brewing process, you’ll need to gather some essential brewing equipment:
- Brew kettle – A large pot (at least 5 gallons) for boiling ingredients.
- Fermenter – A glass or plastic vessel with an airlock to allow fermentation.
- Siphon and tubing – For transferring beer between containers.
- Bottling bucket and bottles – To store and carbonate your finished stout.
- Sanitizer – Absolutely essential for keeping everything clean and free of bacteria.
Ingredients for a Classic Irish Stout
To create an authentic Irish stout, you’ll need the following ingredients:
- Base Malt (Pale Malt or Maris Otter) – Provides the foundation for your beer.
- Roasted Barley – The key ingredient that gives Irish stout its signature dark color and roasted flavor.
- Flaked Barley – Adds body and enhances the creamy head.
- Hops (East Kent Goldings or Fuggle Hops) – Provides a mild bitterness without overpowering the malt.
- Yeast (Irish Ale Yeast) – A good fermenting yeast that complements the beer’s malty profile.
- Water – The backbone of any good beer; filtered water works best.
Step-by-Step Guide to Brewing Irish Stout
Brewing Irish stout is a step-by-step process that requires patience and attention to detail, but don’t worry—I’ll guide you through each stage to ensure success.
Preparing Your Equipment
Sanitation is key in brewing. Before you start, make sure all your equipment, including your kettle, fermenter, and bottles, are thoroughly cleaned and sanitized to prevent contamination.
Mashing the Grains
- Heat about 3 gallons of water to 150-155°F (65-68°C) in your brew kettle.
- Add the crushed grains (pale malt, roasted barley, and flaked barley) to a mesh bag and steep them in the hot water for about 60 minutes.
- This process extracts the fermentable sugars from the grains, which will later turn into alcohol.
The Boil
- Remove the grain bag and bring the liquid (wort) to a rolling boil.
- Add your hops in stages:
- First addition at the beginning of the boil for bitterness.
- Optional second addition toward the end for mild aroma.
- Boil for 60 minutes, stirring occasionally.
Cooling the Wort
- Quickly cool the wort down to around 65-70°F (18-21°C) by placing the brew kettle in an ice bath or using a wort chiller.
- Once cooled, transfer the wort to your sanitized fermenter.
Fermentation
- Pitch your yeast into the cooled wort.
- Attach an airlock to your fermenter and store it in a cool, dark place at 65°F (18°C).
- Fermentation typically takes 7-10 days. You’ll know it’s done when bubbling in the airlock slows significantly.
Bottling and Carbonation
- Once fermentation is complete, siphon the beer into a bottling bucket, avoiding the sediment at the bottom.
- Add priming sugar to carbonate the beer naturally in bottles.
- Cap the bottles and let them sit at room temperature for about 2 weeks before drinking.
Brewing Questions & Troubleshooting
Customize Your Irish Stout for the Perfect Pour
Want to fine-tune your homemade Irish stout? These simple adjustments can enhance the texture, strength, and overall complexity of your brew while keeping it true to its classic character.
- For a creamier head – Increase the amount of flaked barley in your grain bill to enhance head retention and give your stout a smoother, silkier foam. Flaked barley adds unfermentable proteins that contribute to a rich mouthfeel and the signature cascading effect often seen in Irish stouts. A good starting point is to make flaked barley about 10-15% of your total grain bill.
- To boost alcohol content – Slightly increase the ratio of malt, particularly pale malt or Maris Otter, to give your stout a higher original gravity (OG) and, in turn, a stronger alcohol content. Keep in mind that increasing fermentable sugars also affects body and sweetness, so consider adjusting the mash temperature slightly lower (around 148-150°F) for a drier finish or keeping it higher (152-154°F) for more residual sweetness.
- To add complexity – Play with different hop varieties to introduce new layers of flavor without overpowering the malt-forward profile of an Irish stout. Traditional English or Irish hops like East Kent Goldings and Fuggle add mild, earthy, and floral notes, while American varieties such as Cascade or Willamette can bring a touch of citrus and spice. Start with a small addition at the end of the boil or as a dry hop to test how different hops influence the final brew.
By making these small but strategic tweaks, you can personalize your Irish stout to match your ideal balance of texture, strength, and complexity—all while staying true to the rich traditions of this beloved beer style.

Equipment
- 5-Gallon Fermenter with airlock
- Brew Kettle at least 5 gallons
- Strainer or mesh bag
- Thermometer
- Hydrometer to measure alcohol content
- Auto-Siphon & Tubing
- Bottling Bucket with spigot
- 50 Bottles we like the ones with the ceramic caps attached
- Sanitizer
Ingredients
Grains & Malts:
- 6.6 lbs Light Dry Malt Extract 8 lbs Pale Malt (if doing all-grain)
- 1 lb Roasted Barley
- 0.5 lb Chocolate Malt
- 0.5 lb Flaked Barley
Hops & Yeast:
- 1 oz East Kent Goldings Hops
- 1 oz Fuggle Hops
- 1 packet Irish Ale Yeast Wyeast 1084 or Safale S-04
Other Additions:
- 5 gallons Water filtered
- ¾ cup Priming Sugar for bottling
- 1 Whirlfloc Tablet optional
Instructions
- Sanitize everything that will touch your beer to avoid contamination. Use a no-rinse sanitizer and make sure your fermenter, spoon, and siphoning equipment are completely clean before starting.
- In a large brew kettle, heat 3 gallons of water to about 160°F. Add the roasted barley, chocolate malt, and flaked barley in a mesh bag. Let them steep for 20 minutes, like making tea, to extract the rich color and flavor. Remove the grains and let them drain into the pot before discarding them.1 lb Roasted Barley, 0.5 lb Chocolate Malt, 0.5 lb Flaked Barley
- Increase the heat and bring the water to a gentle boil. Remove from heat and stir in the dry malt extract (DME) until fully dissolved. Return the mixture to a boil. Be careful—boilovers can happen fast!6.6 lbs Light Dry Malt Extract

- At 15 minutes: Add 1 oz Fuggle hops for aroma.1 oz Fuggle Hops
- At 10 minutes: If using, add a whirlfloc tablet to help with clarity.1 Whirlfloc Tablet
- After the 60-minute boil, remove the pot from heat. Cool the wort (unfermented beer) as quickly as possible by placing the pot in an ice bath or using a wort chiller. The goal is to get it down to about 70°F.
- Pour the cooled wort into a sanitized fermenter. Add enough cool water to reach 5 gallons. Use a sanitized hydrometer to take an initial gravity reading. Sprinkle or pour in the yeast, close the fermenter, and attach the airlock.1 packet Irish Ale Yeast
- Place the fermenter in a dark, cool space (around 65-70°F) and let it ferment for at least 2 weeks. You’ll notice bubbling in the airlock within the first 24 hours, signaling active fermentation.
- After fermentation is complete, dissolve 3/4 cup priming sugar in 2 cups of boiling water. Cool and mix with the beer in a bottling bucket. Siphon into bottles, cap them, and store in a dark place at room temperature for 2 weeks to carbonate.3/4 cup Priming Sugar
