In this article, we’ll give you all the information you need to age beer in oak barrels successfully. Aging beer in oak barrels is not just about giving it a unique flavor profile – though that’s certainly part of it! It’s also an incredible opportunity for craft brewers and home brewers alike to explore using a beer barrel and creating unique brews. We’ve created many and want to show you how to approach it for your beer.

Choosing The Right Oak Barrel

When it comes to aging beer in an oak barrel, size matters (seriously). A larger sized barrel can influence the flavor profile of a beer much more than a smaller one. It’s important to consider how much space you have available for storing and aging your barrels when deciding on the right size. Typically smaller barrels will age your beer faster but that’s not always a pro, especially if you want to take your time.

You should also think about what type of oak you want your barrel made from; French Oak is often used for wine barrels (and maybe tequila barrels), while American or Eastern European Oaks are best suited for heavier beers like stouts and porters.

The level of toasting and charring that goes into making an oak barrel will also determine its flavor characteristics. It’s even possible to flavor infuse the barrel with anything you might want so even more flavor combos are possible.

Taking all these factors into account is key when selecting the right oak barrel for aging beer.

New American Oak Barrels

When it comes to aging beer in oak barrels, there are many options. From the type of barrel used to the flavors that can be achieved through wood-aging, there is a lot to consider when aging your beer.

First, let’s look at the different types of barrels available. New American White Oak Barrels are the most popular option for brewing and storing beer because they provide strong notes of vanilla and caramel resulting from their intense charring process. Other types of barrels include French, Hungarian, and Russian Oak which vary in flavor profile but all add complexity to beers.

Wood selection matters for aging (more than you’d think) – avoid wood varieties like cedar or pine as they may impart unwanted flavors on your brew. Charring methods should also depend on the type of beer being aged (i.e., light bodied beers need less charring than dark one)

Toasting also has an impact on flavor as it helps bring out additional nuances within each style such as coconut, clove, coffee, chocolate, etc., depending on what kind of wood you’re working with:

  • French Oak
    • Mellow spicy & nutty aromas
    •  Subtle tannin structure
  • Hungarian Oak
  • Full-bodied character
  • Dried fruit & raisin notes
  •  American & Russian Oak
  • Heavy toast levels
  • Smokey & robust characteristics – Balanced tannins with a lingering finish.

Now we need to discuss prepping your barrel including sanitizing steps and cleaning. Sanitization is essential before using any new barrel, as this ensures no bacteria or wild yeasts will affect your beer’s quality.

Prepping The Barrel

Preparing a new American Oak Barrel requires both time and patience, but the results will be worth it! To ensure that your barrel is ready for aging beer, there are a few steps to take.

First, you’ll want to test the staves with various methods to make sure they are fit for use. Sanitizing the inside of the barrel is also important; this can be done by boiling or steaming water in it. Additionally, curing wood may improve flavor profiles over time.

Once these steps have been completed, regular maintenance is necessary in order to sustain freshness and flavor consistency. With proper preparation and storage techniques, your oak barrels will unlock rich flavors and aromas that only aged beer can provide.


Rinsing is a crucial part of this process; if done correctly, you can expect some delicious suds in no time! But what does rinsing entail? Let’s dive into this key step of barrel-aging beer so that you can unlock rich flavors with ease.

Sanitizing techniques are essential when using any kind of brewing equipment, especially oak barrels. It’s important to first rinse out the inside of the barrel with warm water before use to prevent bacteria from spoiling your beer during its aging period.

Regular maintenance will ensure that your barrel continues producing great tasting beer over time. Check for leaks by filling each end of the barrel halfway with water, and monitor alcohol levels every few weeks to ensure that the desired flavor infusion has been achieved.


Moving on from rinsing, it’s time to explore the next step in aging beer in oak barrels: soaking.

It’s essential to understand that each barrel will require different soaking times depending on its size, wood type, and cleaning techniques used. Some may only require a few hours of soaking, while others might need days or even weeks.

Different cleaning methods such as using enzymes versus heat sterilization can have an impact on how quickly your beers age and what kind of taste they take away from the process. Once your barrel is clean, you can start the aging process.

Aging Process

Aging beer in oak barrels is an art that has been around for centuries (and we love it). It’s a process full of experimentation and discovery, as each barrel size, temperature control, flavor profile, and type of beer will yield different results.

When it comes to beer, aging slower is better. You don’t want too much oxygen to come into contact with your beer too quickly or you’ll likely ruin it’s flavor. That’s why we recommend taking it slow and being patient. It won’t matter too much what barrel size you use. You can use a 1 liter oak barrel or something bigger like a 20 liter oak barrel. You’ll still need to take a while. Typical aging can be about ~3 weeks for liquor but you should age longer for beer.

The actual age time for your brew is up to you but around 1-3 months is a good time for smaller barrels and even up to 6 to 12 months for larger barrels.

Bottling And Serving

Once the aging is over, it’s finally time to bottle and serve your delicious aged beer! The complex flavors that have been developed over weeks or months will be sure to impress you and your friends.

Here are four things to keep in mind when bottling and serving:

  1.       Make sure that tasting notes accurately reflect the flavor profile of the finished product.
  2.       Monitor yeast management throughout aging times for optimal carbonation levels.
  3.       Bottle conditioning can lengthen shelf life while allowing additional complexity and carbonation development.
  4.       Pay attention to storage temperature before serving, as this can influence oxidation levels, which could affect quality and taste of the beer.

No matter how you choose to enjoy it, there’s nothing quite like cracking open an oak barrel-aged beer. If you’re looking for beer barrels for sale, don’t wait get them today and make the best home-brew you’ve ever had.
