How to Pitch Yeast into Homebrew Beer Wort: A Detailed Guide

Wednesday, November 1, 2023
For those just embarking on their homebrew journey, the term "pitch your yeast" might be unfamiliar and even a bit intimidating. I remember the panic that set in when I first came across it.  I have to do what to the yeast?

Understanding 'Pitching Yeast'

At its core, 'pitching yeast' is brewer's jargon for introducing yeast to the wort. The term "pitching" is derived from the action of throwing or tossing, much like a baseball pitcher on the mound. This step is vital because yeast, a living microorganism, is responsible for transforming wort into beer. As it consumes the sugars present in the wort, yeast produces carbon dioxide and the alcohol content we associate with beer.

However, yeast is more than just an ingredient; it's a delicate, cell-based life form that requires specific conditions to flourish and generate quality beer. The pitching process isn't merely about adding yeast; it's about ensuring optimal conditions for yeast activation. This concept is applicable not only to beer but also to cider, mead, and seltzer.

The Importance of Temperature

Temperature plays a pivotal role when pitching yeast. If the wort is too hot, especially post-boiling, the yeast cells can be destroyed, halting the fermentation process—a disappointing outcome after investing time and resources. Conversely, if the wort is too cold, the yeast remains dormant and won't initiate fermentation.

Monitoring the temperature is crucial. Some fermenters come equipped with a gauge; however, in its absence, a reliable thermometer is invaluable. Typically, ale fermentation occurs between 68 to 72 °F (20 to 22 °C), while lager fermentation ranges from 45 to 55 °F (7 to 13 °C). It's always wise to refer to the guidelines provided by beer kit manufacturers.

The Art of Yeast Pitching

While there are varied opinions among brewers regarding the best yeast pitching method, newcomers needn't be overwhelmed. Adhering to tried-and-tested brewing instructions should yield satisfactory results. However, it's worth noting that fermenting outside the recommended yeast temperature range can alter the beer's flavor profile, leading to unexpected results.

For those seeking simplicity, 'dry pitching' is straightforward. Once the wort is prepared in a fermenting drum (say, 30 liters) and the temperature is right, open the yeast packet from the beer kit and introduce it directly to the wort. For ease, snip the packet to ensure efficient yeast dispersion. A gentle stir with a sanitized spoon can aid in even distribution. Thereafter, securely seal the fermenter and store it in a conducive environment for a week or two, ensuring it's insulated, especially during colder months.

Hydrating Yeast: An Added Step for Assurance

Serious brewers might opt to pre-hydrate their yeast. 

The rationale? Wort's sugar concentration can sometimes hinder the yeast's ability to hydrate, delaying fermentation onset. This step is particularly beneficial for high gravity worts laden with sugars.

To rehydrate, boil water, allow it to cool, then add the yeast. After about 15 minutes, the mixture should exude a bread-like aroma and exhibit some bubbling. If these signs are evident, the yeast is ready to be pitched. However, if the mixture remains inactive, it's possible the yeast has expired or been compromised.

Determining the Right Yeast Quantity

Typically, one yeast packet suffices for most brews. But for high-alcohol content beers or older yeast packets, doubling up might be beneficial. Wort's density and the type of beer (ale or lager) can also influence the yeast quantity. Lagers, which ferment at cooler temperatures, often require more yeast than ales.

Exploring Liquid Yeast

Liquid yeast, another brewing option, mandates a slightly different approach. It's best to introduce it to a starter wort first, then pitch it to the main wort. This ensures a healthy yeast population, optimizing the fermentation process.

In conclusion, understanding and mastering the yeast pitching process is instrumental in brewing success. By respecting the yeast's needs and ensuring the right conditions, brewers can look forward to a delightful and rewarding beer-making experience.

Using Honey in Beer Brewing: A Sweet Addition to Your Brew

The art of brewing beer has evolved over millennia, and one ingredient that has stood the test of time is honey. While the use of honey in brewing might seem ancient, its application in modern-day brewing remains as intriguing and beneficial as ever. 

This article delves deep into the world of incorporating honey into your beer brewing process, its effects, and the considerations you need to keep in mind.

Honey and Beer: An Age-Old Affair

Using honey to brew beer is a practice that dates back centuries. The addition of bee honey to one's homebrew not only imparts unique aromas but also enriches the flavor profile of the beer. However, it's crucial to distinguish between beer brewed with honey and mead. 

While mead is a beverage made entirely from honey, adding honey to beer results in a concoction known as a "braggot." Although braggots share some characteristics with mead, their primary distinction lies in the brewing process and the balance of ingredients.

The Role of Honey in Boosting ABV

Another fascinating aspect of adding honey to your beer is its potential to elevate the alcohol content (ABV). As honey ferments, it breaks down into alcohol, thereby increasing the beer's overall ABV. This makes honey a dual-purpose ingredient, enhancing both flavor and potency.

Choosing the Right Honey: Quality Over Exoticism

For beginners, it's tempting to experiment with various types of honey, including wild honey from local suppliers. While wild honey can bring distinct flavors, it also poses risks. Wild honey might introduce unwanted bacteria, which could potentially interfere with the yeast during fermentation. 

Moreover, specific regions, like New Zealand where this author resides, face challenges with honey contaminants such as Tutin, which can be toxic. Therefore, for safety and consistency, it's advisable to use standard, high-quality honey that you'd confidently consume or serve to your family.

Incorporating Honey into the Brewing Process

When it comes to adding honey to your brew, timing is of the essence. Typically, brewers introduce honey after mixing in other essential ingredients like malt extract, hops, and DME. To ensure the smooth incorporation of honey, consider warming it slightly, ensuring it remains below boiling point. This softening technique allows honey to blend seamlessly into the fermenter. 

If you're conducting a boil, adding honey as the wort cools (around 160°F or below) might help preserve its innate flavor.

Determining the Right Quantity of Honey

The amount of honey to use largely depends on personal preference and the desired outcome. Some brewers suggest that honey can constitute anywhere from 2% to 10% of the total wort. Others believe that up to 50% of the fermentable sugars can be derived from honey. 

It's essential to strike a balance, as excessive honey might prolong fermentation and impart a more mead-like taste to the beer.

Selecting the Ideal Honey Variety

Different kinds of honey possess distinct characteristics. While any supermarket variety can suffice, maltier honeys tend to accentuate the honey flavor in the beer. However, if you opt for a honey-rich brew, consider increasing the bittering hops to counterbalance the heightened sweetness. This adjustment can ensure a harmonious flavor profile and prevent an overly dry mouthfeel.

Honey as a Carbonating Agent for secondary fermentation

Yes, you read that right! 

Honey can indeed be employed to carbonate beer during bottle conditioning. However, moderation is key. Overdoing the honey might trigger excessive secondary fermentation, leading to over-carbonated beer, often termed "gusher" beer.

How to increase the alcohol content of home brew beer - ABV

Monday, October 23, 2023
In the iconic film "Men in Black," the talented Vincent D'Onofrio portrayed an extraterrestrial with a strong penchant for sugar. This craving mirrors the brewing world's practice of increasing alcohol content. To put it simply: add sugar. However, like many aspects of brewing, the reality is more nuanced.

Understanding Alcohol By Volume (ABV)

In brewing, 'Alcohol By Volume' or ABV, represents the percentage of alcohol in relation to the total volume of beer. If you're aiming to elevate your beer's ABV, the question arises: which sugars can be added to achieve this?

Boosting ABV: The Ingredients

When exploring options to enhance ABV, consider the following ingredients:

- Hopped Malt Extract (HME)

- Liquid Malt Extract (LME)

- Dry Malt Extract (DME)

- Table sugar

- Corn sugar (dextrose)

- Honey

- Brown sugar

The Role of Malt Extracts

Malt extracts, especially DME and LME, serve as primary sugar sources for yeast fermentation. An added pound or 1/2 kg of DME or LME, beyond your recipe's stipulations, can elevate your beer's ABV by approximately half a percent. However, these extracts can alter the beer's overall body, potentially resulting in a maltier finish and a decrease in hop bitterness.

Other Sugars and Their Impact

Incorporating additional sugars like corn sugar, table sugar, and brown sugar can augment the beer's ABV. However, these sugars might render the beer drier, affecting its body and mouthfeel. An increased hop bitterness might also be discernible. Other sweetening agents like maple syrup, golden syrup, and even jelly beans can be experimented with, but they'll invariably influence the beer's flavor profile. 

Some high ABV commercial beers, like King Fisher or Elephant, possess a distinct sweetness. Using these sugars might also cause a lightening in your beer's color.

Honey's Contribution

Honey is not just a delightful sweetener but also a fermentable sugar that yeast thrives on. It imparts subtle flavors and complexity to the beer. Approximately 1 pound of honey can enhance the ABV by around 0.7 percent. Yet, it's worth noting that excessive honey can dry out the beer's taste.

The Risks of Overloading Sugars

Excessive sugar can be detrimental to your brew. It's recommended that no more than a third of your beer's ABV should originate from non-malt sugars. For instance, if crafting a 6 percent ABV beer, avoid adding ingredients contributing over 2 percent to that total. Overloading sugars can strain the yeast, slowing fermentation and altering taste. 

To counteract this, consider introducing more yeast nutrients or even a secondary yeast addition. Some yeasts are more alcohol-resistant than others, so choose wisely. 

Properly aerating your wort before primary fermentation is beneficial, especially when working with a sugar-rich wort.

Temperature and Brewing

Maintaining consistent temperature is paramount in the brewing process. Extreme fluctuations can adversely affect the outcome. If your aim is to amplify the alcohol content, contemplate the myriad variables at play. Making incremental adjustments and closely monitoring the results can lead to successful brews with higher ABV.

A Final Thought: Brewing as Art and Science

Brewing seamlessly blends artistry with scientific precision. While increasing ABV can be an exciting challenge, the ultimate goal remains crafting a beer that resonates with your palate. And if you're ever curious about countering the sweetness in beer, remember the beer style "Gose" that incorporates salt. It might be your next brewing adventure!
