This guide complements the video tutorial, offering detailed explanations and actionable advice for both beginner and seasoned brewers looking to refine their craft with the Anvil Foundry electric brewing system.
Understanding the Anvil Foundry’s All-Grain Brewing System Potential
The Anvil Foundry system, as highlighted in the video, is particularly appealing to those venturing into all-grain brewing. Its integrated design simplifies many complex steps, making it an excellent choice for a first all-grain brew.
While often marketed towards beginners, its robust feature set, including precise temperature control and powerful elements, positions it as a versatile tool for intermediate and even advanced brewers. Operating at either 120 volts or 240 volts, the system adapts to various power setups, with 240V offering significantly faster heating and a more vigorous boil, as demonstrated in the video.
Initial Setup and Pre-Heating Strategies
Effective pre-heating is crucial for a smooth brew day, and the Anvil Foundry excels with its programmable pre-heat function. The video demonstrates setting the strike temperature to 160°F for a 152°F mash, utilizing the full 100% power setting for rapid heating.
A key strategy involves leveraging the timer function to pre-heat overnight. By setting a prolonged timer, such as nine hours, the system can reach your desired strike temperature by morning, significantly reducing active brew day time. Although circulating during pre-heat is an option, the speaker opted against it to prevent the pump from running continuously, preferring manual stirring just before mash-in.
Water Chemistry: The Unsung Hero of All-Grain Brewing
Water chemistry, often overlooked by new brewers, profoundly impacts beer flavor and mash efficiency. For a New England IPA (NEIPA), like the Haze Craze kit featured, adjusting your water profile is paramount to achieving the desired soft mouthfeel and hop expression.
The video showcases a smart modification to a standard pale ale water profile. While a typical pale ale favors a higher sulfate-to-chloride ratio to accentuate bitterness, NEIPAs thrive on a higher chloride-to-sulfate ratio for a softer, fuller, and hazier character. Specifically, the speaker employed 0.5 gram per gallon of gypsum (sulfates) and 1 gram per gallon of chloride, effectively reversing the standard pale ale approach to suit the NEIPA style. This subtle yet impactful adjustment plays a vital role in crafting a truly authentic NEIPA on the Anvil Foundry system.
Mastering the Mash: Temperature, Circulation, and Raking
The mash is where complex starches in the grain are converted into fermentable sugars, a cornerstone of all-grain brewing. Precision in temperature control and efficient circulation are critical for optimal extraction with the Anvil Foundry.
Mashing In and Circulation Dynamics
Upon reaching the 160°F strike temperature, the Anvil Foundry is powered down to introduce the grain. It’s imperative to stir the 13 pounds 4 ounces of grain thoroughly as it’s added to the 6.7 gallons of strike water, ensuring no dry clumps (dough balls) remain. After an initial 10-minute rest, circulation is initiated.
The speaker used a clamped return tube, throttling the pump to about 50% capacity, then further reducing it for a gentle flow. The Anvil Foundry’s new malt pipe design, featuring perforations around the outside, was observed for its performance with oats and flaked wheat, common in NEIPAs. While rice hulls are often recommended for these adjuncts to prevent a stuck mash, the system performed admirably without them in this instance, indicating effective design for managing challenging grain bills. Setting the power to 30% (on 240V) was initially attempted for temperature maintenance, but later adjusted to 40% for consistent 152°F mash temperature control, demonstrating the need for dynamic adjustments.
Temperature Management and Mash Raking
Throughout the one-hour mash, vigilant temperature management is essential. The Anvil Foundry’s controller demonstrated excellent stability, holding the mash temperature within a tight range of 152°F to 153°F. This precise control is vital for enzyme activity and sugar conversion.
Additionally, the manual recommends raking the mash every 15 minutes. This involves gently disturbing the top third of the grain bed after temporarily pausing the pump and removing the top screen. Raking helps to prevent channeling and promotes even liquid flow through the grain bed, further enhancing sugar extraction and overall efficiency. The wort clarity improved noticeably throughout the mash, even with a high proportion of wheat and oats, attesting to the system’s filtration capabilities.
Sparging for Maximum Sugar Extraction
After the mash, the next crucial step in all-grain brewing is sparging, which involves rinsing the grain bed to extract any remaining fermentable sugars. The Anvil Foundry supports this with an integrated malt pipe lift system.
Mash Out and Efficient Wort Collection
Following the 60-minute mash, the temperature is raised to 170°F for a mash out. This step halts enzyme activity and reduces wort viscosity, making the sugars easier to rinse during sparging. The speaker ramped up the temperature slowly, using 50% power to prevent scorching, then turned off the element once 170°F was reached.
The malt pipe is then lifted and rotated 45 degrees to drain into the kettle, supported by a specialized ring. A gallon of sparge water, heated separately (in this case, on an Anvil kettle and induction plate), is slowly poured over the grain bed, ensuring an even rinse. For this particular brew, approximately three-quarters of a gallon of sparge water was used. The volume of collected wort will vary based on the operating voltage; 240V systems typically see more vigorous boils and higher boil-off rates, thus requiring different volume calculations than 120V setups, as specified in the Anvil Foundry’s manual.
The Boil: From Hop Additions to Hot Break
The boil serves multiple purposes: sanitization, hop isomerization (bitterness), hop aroma/flavor, and concentration of the wort. Precision in hop timing is key for tailoring a beer’s profile.
Strategic Hop Additions
The Haze Craze NEIPA recipe called for several hop additions, starting with a unique approach: first wort hopping (FWH). A half ounce of Warrior hops was added to the kettle as wort was collected during sparging. FWH is believed by many brewers to contribute a smoother, less harsh bitterness and enhance hop aroma, setting a foundational hop character early in the process.
During the main boil, the system achieved a vigorous boil at 2800 watts on 240V. The boil timer was set for 45 minutes, at which point the wort chiller was added for sanitization during the remaining 15 minutes. At the 5-minute mark, 1 ounce of Citra hops was added for flavor and aroma. Finally, after turning off the element (“flame out”), an additional 1 ounce of Citra and 2 ounces of whole Mosaic hops (contained in a hop bag to prevent pump clogging) were introduced for maximum aroma and flavor, contributing to the signature NEIPA profile.
Chilling and Post-Boil Care
Rapid chilling is vital to prevent off-flavors and promote a clear beer. The Anvil Foundry’s included chiller, combined with manual stirring, effectively reduced the wort temperature in about 15-20 minutes. Following chilling, the wort was transferred to a Blichmann Conical fermenter for pressurized fermentation, an advanced technique that offers benefits like reduced oxygen exposure and improved fermentation control, especially beneficial for delicate styles like NEIPAs.
Post-Brew Day: Evaluating Efficiency and Organization
A successful brew day culminates in hitting your target numbers and maintaining an organized process, particularly for all-grain brewing with its increased complexity.
Hitting Your Numbers
The Haze Craze kit targeted an original gravity (OG) range of 1.061 to 1.063, based on an estimated 70% brewing efficiency. Impressively, the brew achieved an OG of 1.061, confirming the system’s performance and the effectiveness of the process adjustments made. This outcome validates the Anvil Foundry’s ability to consistently deliver predictable results when parameters are carefully managed. The final volume transferred to the fermenter was approximately 5.5 gallons, with minimal scorching visible at the bottom of the kettle, thanks to the Anvil Foundry’s ultra low wattage density elements.
The Importance of Organization
Transitioning from extract to all-grain brewing involves more steps, making organization critical. As emphasized in the video, laying out your recipe, ingredients, and even pre-smacking your yeast (London Ale 3 in this case) in advance can significantly streamline the brew day. This meticulous preparation minimizes errors and enhances the overall enjoyment of the all-grain brewing process, ensuring a smooth and successful experience with your Anvil Foundry electric brewing system.
