WHAT IS BARREL AGED BEER?

Brewing beer is a science, but brewing great beer is an art. In no other stage of the brewing process is this more true than when it comes to barrel-ageing.

Adding flavour and complexity by ageing beer in barrels is certainly a trend that is exploding Down Under with breweries around the country implementing barrel programs.

For those keen to discover more about this captivating brewing technique, we’ve put together a quick guide. Plus take a gander at some of our favourite barrel-aged beers!

So What Is Barrel Aged Beer?

Barrel aged beer is any lager, ale or hybrid beer that has been aged in a barrel or in contact with wood. Using barrels that previously held spirits and wine, the beer absorbs the flavours creating a unique sort of aftertaste. In this process the beer also takes on the flavours of the wood, normally oak, to further enhance the aroma of the brew.

If you’re feeling a little bit spicy and adventurous there are heaps of different variations of barrel aged beers. You can age beer in barrels that used to contain gin and tequila or change up the type of wood from apple, alder, hickory and plenty more.

What I love about barrel aged beer is how bloody unpredictable it is! Working out how a beer will react in a barrel is a near impossible task as every barrel is different, with even the weather having significant impact on the brew. That means that every barrel-aged beer is, like my mum used to call me, ‘special in its own way’.

What Does It Taste Like?

I know what you’re thinking, why would I want my beer tasting like wood? Well I’ll tell you why, the barrel expands and shrinks based on the weather pushing the beers into different pockets of the barrel. This process infuses the beer with a naturally occurring chemical in the wood called vanillin. Vanillin tastes exactly the same as it sounds and adds a sweet, rich taste to the frothy.

This magical process paired with the tastes from the barrels’ last production will create a beer unlike any you have ever tasted before. My personal favourite is a Japanese Whisky Barrel-Aged Imperial India Pale Ale, which supports my belief that the more syllables the beer name has, the better it tastes. After being aged in old whisky barrels the beer displays flavours of oak and malt while being joined by a fruity and citrus punch from the hops.

Is It Worth the Coin?

It’s no secret that barrel aged beers are pretty pricey ranging from $5 a bottle all the way to over $50. Even though as a beer fanatic I might be a little biased I always recommend barrel aged beers to my mates looking to get into craft beers or those poor souls that say they ‘don’t enjoy beer’.

This is because of the variety of flavour that is only really limited by the brewer’s imagination. When brewers do master this difficult process I can assure you that it leads to some of the most intense, intricate and artistic drinks in the world.
