SA: After going through the Mash and Lauter Tuns, the
mixture is then passed onto the slide Whirlpool Tank. At this stage, all the solids in the mixture are separated from the liquid. It is then passed through the heat exchanger where the cooling process can begin. The temperature is lowered to a certain point so that it is suitable for fermentation to occur. slide
SA: After the beer has been fermented, it then goes through a two step filtration process to get rid of any unwanted particles in the beer. In this picture here (point to picture), you can see the difference between a filtered and an unfiltered beer at Steamwhistle. The beer starts off as a cloudy, yellow liquid and turns into a clear gold liquid and after being filtered. Steamwhistle beer is filtered through Diatomaceous Earth Filtration and Microfiltration. slide
SR: During the Diatomaceous Earth Filtration, beer is passed through a powder made using sedimentary rock. This allows larger particles in the beer such as yeast, barley protein and hops acid to be filtered out. slide
SA: The process of Microfiltration is used to get rid of contaminants from beer and is achieved by passing the beer through a microporous membrane in which the sizes of the pores vary from 0.1 to 10 micrometres in size. slide
SR: Finally, we’re at the last stage of the actual beer brewing process. So here you can see how (point at the picture while explaining) the beer goes from the fermentation tank, through a filtration, and into the storage tank to age for about three to four weeks. The purpose of aging is to smooth out the flavour and to make sure that any unwanted flavours are removed.
A: Now, as we all know, beer bottles come in a few different colour, they can be green, brown or colourless. So why do we have all these different colours? It turns out that the colour of the bottles can actually have an impact on the quality of the beer, the reason being that different coloured bottles let in different amounts of sunlight. Therefore beer companies may choose to package their beer in specific coloured bottles to help protect against sunlight.
N: However, in Steamwhistle case, they don’t focus too much on the colour of the bottles, instead, they choose to shield their beer from sunlight by enclosing them in sealed cases.
They also believe in the importance of having great packaging and is committed to producing the most innovative and creative packaging. I think as consumers we can all agree that we want our products to have nice packaging and Steamwhistle knows this.They focus on having a retro look and feel, hence the use of green coloured bottles. Steamwhistle replicates the beer bottles from the 1950s to stir up nostalgia as well as to pay homage to the Golden Era.
A: So more about the quality of the bottles themselves, they are specially made and are 30% more thicker than the standard beer bottles. The reason for doing this is to have better insulation and product protection therefore the beer is able to remain colder for longer periods of time compared to other companies in the industry.
SR: The process of fobbing also occurs during the packaging of beer. This process is important to the expulsion of oxygen in the bottle before capping the bottles. The surface of the beer is disturbed through shots of small streams of hot water (point at the picture while explaining). This will result in the reaction that fobs the beer. The expulsion of oxygen occurs as the foam rises up to the top of the bottle right before they are capped.
SA: Did you know that Steamwhistle packages about 85000 bottles per day? That may seem like a big number so how do they do it? To ensure that all beer bottles are free from defects and are filled up properly every time, they use cutting edge bottle inspection technology.
SR: Nuspark Inc, a machine manufacturer based in Toronto, provides Steamwhistle with its automated case packing machinery. The picture on the slide shows you a bottle filling line. These machines allow for higher product quality as well as higher packaging efficiency. The automated case packers can produce up to 250 units per minute allowing Steamwhistle to fill and package about 85000 bottles per day with ease.
