Chill… it’s just haze – Chill haze in our Acid Queen

Acid Queen, our granadilla sour ale and the ‘Spring’ series of our seasonal releases, was launched at the beginning of September this year. We are amped –it tastes delicious. Not nearly as tart as last year’s version, the 2017 Acid Queen is refreshing and highly quaffable with a slight tartness that is overcome by the sweetness of the granadilla pulp we added during dry hopping. Life is good.

Life was good… until we noticed the bottles started to accumulate ‘floaties’ about a month after release. At first we were concerned that it was an infection in the bottle but after force-aging and other various tests we have concluded that what we are seeing is in fact the settling out of haze.

This led us to write this post and lay our cards out on the table because although haze may not be particularly lekker to look at, it is not detrimental to the beer (or the beer drinker!) at all. It’s actually part of the flavour. The Acid Queen is quite an unusual beer in our range as it is unfiltered and contains 15 g/L of actual fresh fruit. What we are observing in the Acid Queen is the result of colloidal instability. Bear with us as we attempt to explain the subject and why the Acid Queen is still perfect to drink.

SCIENCE ON! The sediment you see floating in the Acid Queen bottles is a mixture of proteins, carbohydrates and polyphenols. The proteins come from the malt and the polyphenols come from both malt and hops, adding to the mix are pectins. Pectin consists of a complex set of polysaccharides contained in the primary cell wall of plants or fruit. It is the reason for the jelly like consistency in jams so as you can imagine it causes haze in beer. At low temperature proteins, carbohydrates and polyphenols aggregate and form what is known as chill haze. As the beer warms, the haze disappears. Gradually however the haze forming ceases to be reversible and thus becomes permanent haze. This permanent haze clumps together and forms ‘floaties’ which settle to the bottom of a bottle.

 

But fear not! These ‘floaties’ are harmless. Proteins, carbohydrates and polyphenols are present in all beers at varying levels and are part of the flavor, hence why we keep them around (or some of us do). They will even re-suspend when poured into a glass. However, ‘floaties’ at this level are not ideal from an aesthetics perspective, and we are not happy with the visual appearance of the Acid Queen bottles. But we do ask that you continue to enjoy the Acid Queen while we work hard to make sure this doesn’t happen again.

True Brew Appreciation

The craft beer industry is growing fast, with a great and varied selection available to our local market. With so much choice out there, the true path to beer appreciation is through the extremely enjoyable tasting experience that has become a hobby to many an enthusiast.

As one of the largest and most celebrated craft breweries in the Western Cape, we offer informative tastings with a tour of our brewery situated in Woodstock, Cape Town. Tastings on our tours are usually done straight from the tanks, and gives guests an opportunity to meet our incredibly talented local brewers, whose love and passion for their craft truly shines through in all five of our Woodstock Brewery brews currently available.

The secret to beer tasting is engaging your senses. It is usually advised that you should observe a brew that you are sampling by holding it up to the light – is it cloudy or clear? There are so many differentiations in the brews; it is interesting to note the differences. Look at the head of your beer, is it dense or thin? The colour of the head can range from pure white on a Pilsner to light and even medium brown on some stout brews.

Undoubtedly, the best, most enjoyable and most important part is tasting the beer, and it should be savoured. Take a sip and note the initial sensation you feel. Take your time to explore the intricate flavours that have been so meticulously crafted.

As you taste each brew you will notice the true potential for complexity in a beer. Our Pale Ale is malty and medium bodied, while you will taste hints of citrus in our popular Californicator brew. Our German Pilsner, aptly named Happy Pills, will leave you with a slightly spicy aroma and a crisp hop finish. The Wit Beer is a complex treat brewed with fresh orange and coriander. Appreciate the lingering zing and relish the tincture that remains when tasting our growing range of brews.

After enjoying a leisurely tasting and tour of Woodstock Brewery, we suggest our guests head upstairs to The Woodstock Grill & Tap for a tasty bite and your new found favourite Woodstock Brewery beer. For those of you who would like to sample our brews but don’t have time for a tour, tasting trays are available from Woodstock Grill & Tap for your convenience.
