Let’s dive into the process and craft a brew that’s perfect for cozy evenings and festive gatherings.
Ingredients
To craft an authentic Bock Beer, we need to focus on selecting the right components that bring out the full-bodied maltiness and smooth flavor typical of this style. Below, we break down the essential ingredients that will make our bock rich, balanced, and delicious.
Malt and Grains
The backbone of any Bock Beer is its rich malt profile. We use a combination of malts to achieve the characteristic deep amber to dark brown color and layered sweetness.
- Pilsner Malt (8 lbs): Provides a clean, light malt base and fermentable sugars.
- Munich Malt (3 lbs): Adds depth with a toasty, biscuity flavor and amber hue.
- Vienna Malt (2 lbs): Contributes a subtle sweetness and amber glow.
- Caramel/Crystal Malt (60L) (1 lb): Enhances sweetness and imparts a rich caramel color.
- Chocolate Malt (0.5 lbs): Adds complexity with slight roasted notes and darker color.
We carefully balance these malts to create a smooth yet full-bodied Bock foundation packed with layers of malt flavor.
Hops
Hops in a Bock Beer provide subtle bitterness to balance malt sweetness while preserving the malt-forward nature.
| Hop Variety | Amount | Timing | Purpose |
|---|---|---|---|
| Hallertau | 1 oz | 60 minutes | Mild bitterness and aroma |
| Tettnang | 0.5 oz | 15 minutes | Aroma enhancement |
We choose traditional German noble hops, like Hallertau and Tettnang, for their gentle bitterness and delicate floral aromas, ensuring hops never overpower the malt character.
Yeast
Selecting the right yeast strain is crucial in Bock Beer brewing because it impacts flavor, attenuation, and mouthfeel.
- Munich Lager Yeast (Wyeast 2206 or White Labs WLP820): This is our preferred yeast. It ferments cleanly with moderate attenuation, producing a smooth, malty profile without fruity esters that allows the malt to shine.
- Fermentation Temperature: We maintain 48-55°F (9-13°C) for a controlled, slow fermentation that develops complexity.
Water and Other Additives
Water chemistry can influence the final flavor and mouthfeel of our Bock Beer. We recommend using:
- Soft to moderately hard water with balanced calcium and sulfate to accentuate malt sweetness and smoothness.
- Gypsum (Calcium sulfate): Add 1-2 grams per gallon to enhance hop bitterness subtly without overshadowing malt.
- Calcium chloride: Use 0.5-1 gram per gallon to round out the mouthfeel and add fullness.
- No adjunct sugars: To preserve the traditional malt-heavy body, we avoid corn or rice and rely solely on malt-derived sugars.
Careful water adjustment and purity help achieve the velvety texture and clean finish Bock Beer is known for.

Brewing Instructions
Brewing a bock beer requires precision and patience to bring out its signature malt richness and smooth character. Let’s dive into the step-by-step process to craft this classic German brew with care and expertise.
Mashing Process
Start by heating 10 gallons of water to about 150°F (65°C) in your mash tun. We aim for a mash temperature between 148°F and 152°F (64°C – 67°C) to maximize fermentable sugars while retaining malt complexity.
- Add the crushed malted grains (Pilsner, Munich, Vienna, Caramel/Crystal, and Chocolate malts) slowly while stirring to avoid clumps.
- Maintain the temperature consistently within the target range for 60 minutes to allow enzymatic conversion of starches into sugars.
- Stir gently every 15 minutes to ensure even temperature distribution and mash consistency.
Mashing at a precise temperature will influence the body and sweetness that define a bock beer. Let’s keep the mash steady and reliable.
Lautering and Sparging
Once mashing is complete, it’s time to separate the liquid wort from the grain bed.
- Slowly drain the sweet wort into the brew kettle through a false bottom or strainer to avoid grain particles.
- Collect the first runnings carefully; these have the highest sugar content.
- Perform sparging by rinsing the grains with 170°F (77°C) water to extract residual sugars. Use about 4 gallons.
- Avoid sparging too fast to prevent channeling and grain bed compaction.
This step is crucial for extracting maximum malt flavor without excessive tannins, keeping the brew smooth and full-bodied.
| Step | Temperature | Duration | Purpose |
|---|---|---|---|
| Mash | 148-152°F | 60 minutes | Starch to sugar conversion |
| Sparge water | 170°F | As needed | Sugar extraction from grains |
Boiling the Wort
Bring the collected wort to a vigorous boil for 60 to 90 minutes.
- Boiling sterilizes the wort and helps concentrate flavors.
- Watch for boil-overs during the initial minutes.
- Skim off any foam or protein buildup for clarity.
A long boil will deepen the malt complexity, a hallmark of a traditional bock beer’s profile.
Adding Hops
We recommend using German noble hops such as Hallertau or Tettnang to preserve the subtle bitterness.
- Add hops according to the schedule below to balance malt sweetness with gentle bitterness:
| Time (minutes) | Hop Addition | Purpose |
|---|---|---|
| 60 (start) | 1 oz Hallertau | Bittering |
| 15 | 0.5 oz Tettnang | Flavor |
| 5 | 0.5 oz Hallertau | Aroma |
- Avoid over-hopping as bock beers thrive on malt dominance with subtle hop presence.
Cooling the Wort
Rapid chilling is essential to prevent contamination and prepare for yeast pitching.
- Use a wort chiller to bring the temperature down to 50°F (10°C) as quickly as possible.
- Immersion or counterflow chillers work best for efficiency.
- Once cooled, transfer the wort to the sanitized fermenter immediately.
“Quick cooling locks in the rich malt aromas and sets the stage for clean fermentation.”
By mastering these brewing instructions, we ensure our bock beer attains its characteristic velvety body and complex malt profile, ready for fermentation and maturation.
Fermentation
Fermentation is the critical stage where our bock beer develops its signature rich malt character and smooth finish. By carefully managing yeast activity and temperature, we can enhance the depth and balance that define this traditional brew.
Pitching the Yeast
To begin fermentation, we pitch the Munich Lager Yeast at the correct amount and condition to promote a clean, efficient fermentation. Here’s what we focus on:
- Yeast Starter Preparation: Prepare a yeast starter 24-48 hours before pitching to ensure yeast vitality and sufficient cell count.
- Pitch Rate: Aim for approximately 1 million cells per milliliter per degree Plato of wort gravity. For a typical bock at 16° Plato (~1.066 SG), this means pitching around 160 billion yeast cells.
- Oxygenation: Aerate the cooled wort vigorously just before pitching to supply oxygen, which aids healthy yeast reproduction.
“Proper pitching sets the foundation for a well-fermented bock with clean flavors and balanced maltiness.”
Fermentation Temperature and Duration
Maintaining the right fermentation temperature is crucial for controlling yeast metabolism and resulting flavor profile. For bock beer, we recommend:
| Fermentation Stage | Temperature Range (°F) | Duration | Notes |
|---|---|---|---|
| Primary Fermentation | 48-54 | 10-14 days | Cooler end yields cleaner flavors |
| Diacetyl Rest (final 2 days) | Gradually raise to 58-60 | 2 days | Helps yeast clean up buttery off-flavors |
- Primary: Keep the wort in a controlled environment to avoid temperature spikes that cause unwanted esters.
- Diacetyl Rest: Near the end, gently warm the beer to encourage yeast to reabsorb diacetyl, ensuring a smooth flavor.
Our patient approach during fermentation allows the malt sweetness and subtle hop bitterness to mature into the velvety body typical of bock.
Secondary Fermentation (Optional)
After primary fermentation, we may choose to perform a secondary fermentation to clarify the beer and develop additional complexity:
- Transfer: Carefully siphon the beer off the yeast sediment into a sanitized secondary fermenter.
- Temperature: Maintain at 35-45°F (lagering temperature).
- Duration: 4-8 weeks or longer for deeper maturation.
This lagering phase encourages:
- Further smoothing of flavors
- Natural carbonation development
- Improved clarity and color deepening
“Secondary fermentation is optional but highly recommended for true bock aficionados seeking that silky texture and refined taste.”
By controlling yeast pitching, fermentation temperature, and time, we cultivate a bock beer that perfectly balances its rich malt foundation with clean, smooth notes that will please every pallette.
Bottling and Conditioning
Bottling and conditioning are crucial steps in locking in the smooth maltiness and rich flavor profile of our bock beer. Proper execution ensures the beer develops ideal carbonation and a refined character over time.
Priming Sugar Addition
To achieve the perfect carbonation, we need to add priming sugar just before bottling. This sugar feeds the remaining yeast, allowing gentle fermentation inside the sealed bottle to produce natural CO2.
- Use corn sugar (dextrose) for a clean, neutral sweetness that won’t alter the bock’s flavor.
- The typical dosage is 3/4 cup (approximately 150 g) of corn sugar per 5 gallons (19 L) of beer.
- Dissolve the priming sugar in 2 cups (475 mL) of boiling water to sanitize, then cool the solution before gently mixing it with the beer.
| Quantity | Measurement | Purpose |
|---|---|---|
| Corn Sugar (Dextrose) | 3/4 cup (150 g) | Priming sugar for carbonation |
| Boiling Water | 2 cups (475 mL) | Dissolve and sanitize sugar |
| Volume of Beer | 5 gallons (19 liters) | Batch size for dosage ratio |
Pro Tip: Avoid vigorous stirring when mixing priming sugar with beer to prevent oxygenation that can cause off-flavors.
Bottling Process
We bottle our bock beer carefully to maintain sanitation and carbonation potential. Here’s how we proceed:
- Sanitize all bottles, caps, bottling bucket, and siphoning equipment thoroughly.
- Use a sanitized siphon to transfer beer from the fermenter to a bottling bucket, ensuring the priming sugar solution is evenly mixed in.
- Fill bottles leaving about 1 inch (2.5 cm) of headspace at the top to allow for expansion.
- Cap bottles with sanitized caps immediately after filling.
- Store bottles upright in a cool, dark area for initial conditioning.
Carbonation and Aging Time
Our bock beer requires patience during carbonation and aging to develop its signature smoothness and depth.
- Bottle conditioning time: 2 to 3 weeks at 65-70°F (18-21°C) to allow CO2 to build up naturally.
- After carbonation, move bottles to a cooler environment (around 50°F or 10°C) for extended aging.
- Recommended aging duration: 4 to 6 weeks, though longer maturation (up to 3 months) enhances complexity and mellows the malt profile.
| Stage | Temperature | Duration | Notes |
|---|---|---|---|
| Primary Conditioning | 65-70°F (18-21°C) | 2-3 weeks | Natural carbonation builds in bottles |
| Secondary Aging | ~50°F (10°C) | 4-6 weeks or longer | Maturation deepens flavor and smoothness |
“Great bock beer is worth the wait. The conditioning phase is where complexity blooms and velvety mouthfeel truly shines.”
By following these bottling and conditioning practices carefully, we ensure each bottle of bock beer delivers the rich malt character and smooth finish that define this classic German brew.
