| Fuggle | 0.5 oz | 4.5% | Aroma/Mild bitterness | Last 15 min |
Yeast
The yeast strain is a cornerstone for replicating Guinness’s signature smoothness and slight fruitiness:
- Irish Ale Yeast (Wyeast 1084 or White Labs WLP004 Irish Ale): Known for moderate attenuation and clean, malt-forward fermentation with subtle esters.
Water
Authentic Guinness relies heavily on water chemistry to mimic its profile:
| Parameter | Target Level |
|---|---|
| pH | 5.2 – 5.4 |
| Calcium (Ca2+) | 50-70 ppm |
| Magnesium (Mg2+) | 5-10 ppm |
| Sulfate (SO4) | 20-30 ppm |
| Chloride (Cl-) | 30-40 ppm |
We recommend using soft water adjusted with calcium sulfate and calcium chloride to achieve this balance for malt richness and smoothness.
Other Additives
To complete the Guinness Clone, subtle additions support the head formation and mouthfeel:
- Irish Moss or Whirlfloc Tablet (optional, 1 tsp or one tablet) – Clarifies the beer by aiding protein coagulation during the boil.
- Lactose (Milk Sugar): 0.25 lb – Adds slight sweetness and body without fermenting, contributing to creamy mouthfeel.
- Carbonation: Target 1.8-2.0 volumes CO₂ for that smooth, velvety finish typical of Guinness.
With these ingredients in hand, we set the stage to brew an authentic tasting Guinness Clone stout that highlights rich malts, subtle hop bitterness, and a creamy texture.

Preparation
To brew our Guinness Clone, precise preparation is key. We will walk through each step to ensure we extract the full depth and character of this iconic stout.
Preparing the Grains
Start by assembling the malt blend that forms the backbone of our Guinness Clone. We combine various malts to achieve the signature roasted, creamy profile:
- Pale Malt: The base malt providing fermentable sugars and body.
- Flaked Barley: Adds smoothness and a creamy mouthfeel.
- Roasted Barley: Essential for deep color and roasted coffee notes.
- Chocolate Malt: Contributes subtle chocolate and additional roasted flavor.
- Caramel/Crystal Malt (60L): Provides slight sweetness and complexity.
Weigh each grain accurately to maintain recipe balance. Next, crush the grains coarsely to optimize sugar extraction during mashing but avoid pulverizing to prevent a stuck mash.
“Proper grain preparation sets the stage for an authentic stout rich in flavor and texture.”
| Malt Type | Amount (lbs) | Role in Flavor |
|---|---|---|
| Pale Malt | 6.0 | Fermentable base |
| Flaked Barley | 1.0 | Creamy texture |
| Roasted Barley | 1.0 | Dark color, roasted notes |
| Chocolate Malt | 0.5 | Chocolate undertones |
| Caramel/Crystal Malt | 0.5 | Sweetness, complexity |
Heating the Water
Water temperature and quality are critical for our Guinness Clone. We recommend using filtered or spring water adjusted to a target profile that matches the smooth Irish stout:
- Target pH: 5.2 – 5.6 for mashing to optimize enzyme activity.
- Water Hardness: Moderate sulfate to chloride ratio, around 1:1.5, to accentuate maltiness without excessive bitterness.
Begin by heating 3.5 gallons of water to 165°F (74°C). This will allow us to mash in the crushed grains efficiently, bringing the temperature down to the ideal mash temperature of 152°F (67°C).
“Precise water heating maximizes starch conversion and sets the foundation for balanced bitterness and smoothness.”
Use a reliable thermometer for accurate temperature control. Stir the water gently while heating to maintain even temperature distribution and prevent scorching.
| Parameter | Target Value | Purpose |

| Volume | 3.5 gallons | Sufficient for proper mash thickness |
| Temperature | 165°F (74°C) | Pre-mash water temperature |
| pH | 5.2 – 5.6 | Optimal enzymatic activity |
| Sulfate:Chloride Ratio | ~1:1.5 | Enhance malt smoothness |
Brewing Process
The Brewing Process for our Guinness Clone Recipe is crucial to replicating the distinct roasted flavor and velvety mouthfeel of the original. We’ll guide you through each step with precision to ensure excellent results.
Mashing
We start by heating our water to precisely 152°F (67°C) to activate the enzymes needed for converting starches into fermentable sugars. The malt blend—Pale Malt, Flaked Barley, Roasted Barley, Chocolate Malt, and Caramel Malt—is added gradually to avoid clumping.
We maintain this temperature for 60 minutes to ensure complete conversion. During this stage, the mash thickens, releasing sweet malt flavors balanced with early roasted undertones. Stir gently but consistently to promote even heat distribution.
| Step | Parameter | Purpose |
|---|---|---|
| Water Temp | 152°F (67°C) | Optimize enzyme activity |
| Mash Time | 60 minutes | Full starch conversion |
| Malt Mix | Pre-milled grains | Sugar and flavor extraction |
Lautering
After mashing, we carefully drain the sweet liquid known as wort. We sparge the malt bed with 168°F (76°C) water to rinse residual sugars, maintaining a slow and steady flow to avoid compacting the grain bed. This step maximizes sugar extraction while preserving clarity.
The flow rate should be about 1 gallon every 4 minutes. We collect approximately 6 gallons (22.7 liters) of wort, which provides enough volume for the next stages and proper wort concentration.
Boiling and Adding Hops
We bring the wort to a rolling boil for 60 minutes to sterilize it and drive off unwanted volatiles. During the boil, timing of hop additions is critical for balancing bitterness and aroma.
| Time (minutes) | Add-in | Purpose |
|---|---|---|
| 60 | East Kent Goldings (1 oz) | Base bitterness |
| 15 | Fuggle hops (0.5 oz) | Mild bitterness, earthy aroma |
| 5 | Irish Moss (0.5 tsp) | Protein coagulation, clarity |
We carefully add hops according to the above schedule to ensure our Guinness Clone maintains the perfect subdued hop character integral to the classic profile.
Cooling the Wort
Post-boil, we rapidly cool the wort to yeast-pitching temperature, typically between 65–70°F (18–21°C), to reduce contamination risk and favor healthy fermentation. We recommend using a wort chiller—either immersion or counterflow—for fast cooling within 20 minutes.
Cooling promptly also helps develop the smooth and creamy texture synonymous with Guinness. Once cooled, we transfer the wort to the sanitized fermenter, ready for pitching the yeast to begin fermentation.
Fermentation
Fermentation is a critical stage in crafting our Guinness Clone, transforming the wort into the rich, velvety stout we desire. This process requires precise control over yeast pitching, temperature, and timing to replicate the classic smoothness and subtle fruitiness that define Guinness.
Pitching the Yeast
We begin fermentation by carefully pitching the Irish Ale Yeast once the wort has cooled to between 65°F and 70°F (18°C – 21°C). Pitching at this temperature range ensures optimal yeast activity, preventing unwanted off-flavors and promoting a clean fermentation profile.
Ensure the yeast is well-hydrated if using dry yeast or properly propagated if using liquid yeast. Gently aerate the wort before yeast addition, as oxygen is essential for yeast growth but should be limited after the initial phase to avoid oxidation.
Primary Fermentation
The primary fermentation takes place over 7 to 10 days at a stable temperature of 68°F (20°C). During this phase, the yeast consumes fermentable sugars, producing alcohol, carbon dioxide, and flavor compounds essential to the stout’s character.
Monitor the specific gravity daily using a hydrometer. Once the gravity stabilizes near 1.010 to 1.012, primary fermentation is complete. Maintaining steady temperature is crucial to prevent stress on the yeast, which can cause off-flavors or incomplete fermentation.
| Parameter | Range/Value | Importance |
|---|---|---|
| Pitching Temperature | 65°F – 70°F (18-21°C) | Optimal yeast vitality |
| Fermentation Time | 7-10 days | Complete sugar conversion |
| Primary Temp | 68°F (20°C) | Balanced flavor and yeast performance |
| Final SG Range | 1.010 – 1.012 | Indicates fermentation completion |
Secondary Fermentation
After primary fermentation, we transfer the beer carefully to a secondary fermenter, leaving behind sediment. The secondary phase lasts 2 to 3 weeks at 60°F to 65°F (15°C – 18°C). This stage allows the yeast to clean up unwanted by-products such as diacetyl and helps develop the stout’s characteristic creaminess and smooth mouthfeel.
Secondary fermentation also enhances clarity and flavor mellowing, ensuring the Guinness Clone is as refined as the original. Avoid aeration during this phase to preserve the beer’s delicate profile.
By adhering to these carefully controlled fermentation steps, we capture the authentic richness and smooth texture that make Guinness a global icon.
Conditioning and Carbonation
Conditioning and carbonation are crucial stages in perfecting our Guinness Clone. These steps develop the beer’s silky mouthfeel, enhance flavor complexity, and create the signature creamy head associated with the original stout.
Carbonation Techniques
Achieving the right level of carbonation is critical. Guinness boasts a uniquely smooth and moderate carbonation that sets it apart from other stouts. We recommend using natural carbonation through bottle conditioning or kegging with CO2 injection for precise control.
Natural carbonation involves adding a specific amount of priming sugar before sealing the beer. The yeast consumes this sugar, producing CO2 that carbonates the beer naturally.
| Priming Sugar Type | Amount per 5 Gallons | Notes |
|---|---|---|
| Corn Sugar (Dextrose) | 3.0 oz (85 g) | Gives a clean, neutral carbonation |
| Table Sugar (Sucrose) | 3.25 oz (92 g) | Slightly sweeter, may affect flavor subtly |
| Dry Malt Extract | 3.5 oz (100 g) | Adds a touch of malt character with fizz |
Steps for Bottle Conditioning:
- Boil the priming sugar with a small amount of water for 5 minutes to sanitize it.
- Cool and gently mix it with the fully fermented beer without introducing oxygen.
- Fill and cap bottles, then store them at 65°F to 70°F (18°C – 21°C).
- Allow 2 to 3 weeks for carbonation to develop fully.
If we opt for kegging, we force carbonate by chilling the beer and applying CO2 at 12-15 psi for 5-7 days, checking carbonation levels regularly to avoid overcarbonation. This method offers greater consistency and faster results.
Aging the Beer
Proper aging or conditioning allows the Guinness Clone to mature, improving taste and smoothness. Aging in a cool, dark place at 50°F to 60°F (10°C – 15°C) for 3 to 4 weeks is ideal.
During aging, yeast and residual sugars continue subtle activity to:
- Soften harsh flavors
- Enhance malt complexity
- Develop the iconic creamy texture
We recommend minimizing oxygen exposure during this phase to prevent off-flavors. Using oxygen-absorbing bottle caps or purging kegs with CO2 before filling helps maintain freshness.
Aging Timeline Overview:
| Phase | Temperature (°F) | Duration | Key Benefits |
|---|---|---|---|
| Conditioning (carbonation) | 65 – 70 | 2 – 3 weeks | Carbon dioxide development |
| Aging (flavor maturity) | 50 – 60 | 3 – 4 weeks | Flavor smoothing, complexity boost |
In following these conditioning and carbonation techniques, we ensure our Guinness Clone delivers that authentic velvety smoothness and perfect creamy head synonymous with the legendary stout.
