- Bring wort to a vigorous boil for 60 minutes.
- Add Hallertau Mittelfrüh hops at the start of boil for bitterness.
- Add Saaz hops during the last 15 minutes for aroma.
- If using, add dark sugar in the final 10 minutes to dissolve completely.
- Cool wort rapidly using a wort chiller to below 70°F (21°C) to prepare for yeast pitching.
Cooling efficiently prevents contamination and preserves the bright malt character that defines a classic Bock beer.
Brewing Process
The Brewing Process for our Bock recipe demands precision and care to capture its robust maltiness and smooth finish. Each stage from mashing to cooling shapes the character of this traditional lager.
Mashing
We begin with Mashing, where crushed malts—primarily Munich Malt, Pilsner Malt, Caramel Malt, and Melanoidin Malt—are combined with heated water. Maintaining a temperature between 150°F to 154°F (65°C to 68°C) optimizes enzymatic activity, converting starches into fermentable sugars. We stir gently for about 60 minutes, ensuring even heat distribution and thorough saccharification.
Key points for mashing:
| Step | Details |
|---|---|
| Water temperature | 150°F to 154°F (65°C to 68°C) |
| Duration | 60 minutes |
| Malt types used | Munich, Pilsner, Caramel, Melanoidin |
| Purpose | Convert starches into sugars |
We monitor the mash consistency closely, aiming for a thick porridge-like texture which yields a full-bodied, malt-forward profile characteristic of Bock.
Lautering and Sparging
Once mashing completes, we move to Lautering and Sparging. Lautering separates the liquid wort from solid grain husks by draining it through the false bottom of the mash tun. We then sparge by gently rinsing the grains with water heated to 170°F (77°C) to extract residual sugars without leaching unwanted tannins.
Steps summary:
| Process | Temperature | Goal | Notes |
|---|---|---|---|
| Lautering | N/A | Separate clear wort | Avoid stuck mash |
| Sparging | 170°F (77°C) | Extract remaining sugars | Use gentle water flow |
Careful control prevents over-extraction which can cause astringency and ensures we capture the malt sweetness essential to Bock’s character.
Boiling and Adding Hops
Next, we bring the wort to a rolling boil for 60 to 90 minutes. This concentrate step balances the malt backbone and sterilizes the wort. We add hops carefully to maintain the Bock’s mild bitterness and aroma, predominantly using Hallertau Mittelfrüh hops with optional late additions of Saaz hops.
We follow this hop schedule:
| Time (minutes) | Hop Type | Purpose | Quantity (for 5 gallons) |
|---|---|---|---|
| 60 (start boil) | Hallertau Mittelfrüh | Bitterness | 1 oz |
| 15 (late add) | Hallertau Mittelfrüh | Aroma | 0.5 oz |
| 5 (optional) | Saaz hops | Delicate aroma/spice | 0.25 oz |
We avoid excessive hopping to preserve the rich malt character that defines the style.
Cooling the Wort
After boiling, prompt cooling of the wort to around 50°F to 55°F (10°C to 13°C) prepares it for fermentation and prevents bacterial contamination. We use an immersion wort chiller or plate chiller, circulating cold water through coils submerged in the hot wort.
Steps for effective cooling:
- Submerge the wort chiller immediately after boil ends.
- Circulate cold water continuously.
- Aim to cool wort within 30 minutes.
- Monitor temperature carefully with a digital thermometer.
Rapid cooling also locks in the bright malt flavors and ensures a clean fermentation by the lager yeast. Once cooled, we transfer wort to the sanitized fermenter, ready to pitch yeast and begin the transformation to a rich traditional Bock.
Fermentation
The Fermentation stage is crucial for developing the distinctive malt richness and clean finish of our Bock recipe. Precise control during this phase ensures optimal yeast performance and flavor balance.
Pitching the Yeast
We begin by Pitching the Yeast into the cooled wort, maintaining a temperature between 50°F and 55°F (10°C to 13°C). Using a lager yeast strain such as Saccharomyces pastorianus is imperative to achieve the classic smooth profile of a Bock.
- Yeast Pitching Rate: Pitch at roughly 0.75 to 1 million cells/mL per °Plato for a healthy fermentation.
- Aerate the wort adequately before pitching to ensure yeast vitality but avoid excessive oxygenation that may affect flavor.
| Parameter | Temperature Range | Yeast Pitching Rate |
|---|---|---|
| Wort Temperature | 50°F to 55°F (10°C-13°C) | 0.75 to 1 million cells/mL/°Plato |
| Yeast Type | Lager (e.g., Saccharomyces pastorianus) | — |
“Pitching yeast at the right temperature and cell count sets the foundation for a clean, balanced Bock with robust malt character.”
Primary Fermentation
Once the yeast is pitched, Primary Fermentation commences and typically lasts 7 to 14 days. Maintaining a stable temperature range of 50°F to 55°F (10°C to 13°C) is critical to prevent off-flavors and promote a clean lager profile.
- Monitor the fermentation progress daily by checking specific gravity.
- Expect a steady decline as sugars convert into alcohol and CO2.
- Avoid temperature fluctuations as they can induce unwanted esters or diacetyl.
During this stage, the beer develops its characteristic malt sweetness and begins to clear.
| Fermentation Phase | Duration | Temperature | Key Notes |
|---|---|---|---|
| Primary Fermentation | 7 to 14 days | 50°F to 55°F (10°C-13°C) | Maintain steady temp, monitor gravity |
Secondary Fermentation (Optional)
For enhanced clarity and flavor refinement, we recommend a secondary fermentation (lagering) phase lasting 4 to 6 weeks at cooler temperatures, around 35°F to 40°F (2°C to 4°C).
- Transfer the beer gently to a secondary vessel to avoid oxidation.
- This phase allows the yeast to clean up residual compounds, improving smoothness.
- Extended lagering deepens the malt complexity and creates the signature silky mouthfeel of Bock.
| Lagering Phase | Duration | Temperature | Benefits |
|---|---|---|---|
| Secondary Fermentation | 4 to 6 weeks | 35°F to 40°F (2°C-4°C) | Clarity, flavor refinement, smooth finish |
Bottling and Conditioning
After fermentation and lagering, careful bottling and conditioning are essential to preserve the rich malt character and achieve the smooth finish that defines a classic Bock. Let’s walk through the precise steps to bottle and condition our brew for optimal flavor and carbonation.
Preparing Bottles
Sanitation remains our top priority during this stage to avoid contamination that can spoil the delicate malt profile of our Bock. Here’s what we do:
- Select brown glass bottles to protect beer from UV light degradation.
- Inspect bottles for chips or cracks; discard any damaged ones.
- Wash bottles thoroughly with hot water and a brewery-approved cleaner.
- Rinse bottles well to remove all detergent residue.
- Sanitize bottles using a no-rinse sanitizer (e.g., Star San), submerging all surfaces and air-drying on a clean rack.
- Prepare sanitized bottle caps and tools such as a capper for secure sealing.
By meticulously cleaning and sanitizing, we ensure our Bock remains pristine during aging.
Carbonation Process
Achieving the right carbonation is vital for the full-bodied mouthfeel and balanced flavor of Bock. We recommend natural bottle conditioning through priming sugar:
- Calculate priming sugar quantity according to the desired carbonation level, typically 2.2 to 2.5 volumes of CO2 for a traditional Bock.
- Prepare a measured amount of corn sugar (dextrose) dissolved in boiling water to sterilize.
- Cool the sugar solution and gently mix it into the fully fermented beer, evenly distributing without oxygenating.
- Use a siphon to fill bottles, leaving about 1 inch (2.5 cm) of headspace to allow carbonation pressure.
- Cap bottles tightly using sanitized caps and a capper.
| Carbonation Detail | Amount/Range | Notes |
|---|---|---|
| Target CO2 Volume | 2.2 – 2.5 volumes | Traditional Bock carbonation |
| Priming Sugar | ~4.5 oz (128 g) per 5 gallons | Adjust based on temperature and batch size |
| Headspace in Bottle | ~1 inch (2.5 cm) | Prevents overflow during carbonation |
“Proper carbonation unlocks the signature effervescence and mouthfeel of our deep amber Bock.”
Aging and Storage
Conditioning the bottled Bock is a crucial final step for flavor development and clarity enhancement:
- Store bottles upright at room temperature (about 65°F to 70°F / 18°C to 21°C) for 2 to 3 weeks to allow carbonation.
- After carbonation is complete, move bottles to a cool dark place between 35°F and 45°F (2°C to 7°C) for 6 to 8 weeks of cold conditioning (lagering).
- This extended cold aging will:
- Smooth out any rough edges or off-flavors.
- Allow proteins and yeast particles to settle, yielding crystal-clear beer.
- Enhance malt complexity and develop that silky mouthfeel characteristic of Bock.
“Patience in conditioning transforms our brew into a robust, smooth, and beautifully clean lager.”
Following these bottling and conditioning protocols ensures our Bock reaches its full potential as a traditional, hearty German lager worthy of any cooler season enjoyment.
