When it comes to enjoying a delicious pint of Guinness, you might have noticed that it is available in both bottles and cans. While the beer itself remains the same, there are a few key differences between Guinness in a bottle and Guinness in a can that are worth exploring.
1. Carbonation
One of the primary differences between Guinness in a bottle and Guinness in a can is the carbonation level. Guinness in the bottle is carbonated with CO2, similar to most other canned and bottled beers. On the other hand, Guinness in the can has a special feature known as a “widget.”
2. The Widget
The widget is a small, hollow plastic device that is inside the can of Guinness. This widget plays a crucial role in ensuring that the beer has the perfect level of carbonation and that it mimics the experience of having a pint of Guinness on tap at a pub. When you open the can, the widget releases nitrogen into the beer, creating a cascade effect and giving it that smooth and creamy texture.
3. Nitrogen Infusion
Thanks to the widget, Guinness in a can undergoes a nitrogen infusion process. This process is what sets it apart from Guinness in a bottle. Nitrogen-infused beer is known for its velvety mouthfeel and creamy head, providing a unique drinking experience compared to carbonated beers.
4. Texture and Mouthfeel
The difference in carbonation and nitrogen infusion impacts the texture and mouthfeel of Guinness in the bottle versus the can. Guinness in the bottle tends to have a slightly higher carbonation level, which leads to a more lively and effervescent mouthfeel. On the other hand, Guinness in the can offers a smoother and creamier texture, thanks to the nitrogen infusion.
5. Aesthetic Appeal
When it comes to the visual aspect, Guinness in a bottle and Guinness in a can also have slight differences. Guinness in the bottle often sports a dark brown glass that adds a touch of sophistication to the drinking experience. Guinness in the can, on the other hand, is typically packaged in an aluminum can, which is lightweight and convenient for on-the-go consumption.
6. Pouring Techniques
Another significant distinction between Guinness in a bottle and Guinness in a can is the pouring technique. Pouring Guinness from a bottle requires a more straightforward technique, as it relies on the carbonation alone to create a foamy head. In contrast, pouring Guinness from a can with the widget requires a specific method. As you tilt the glass and pour the beer gently, the nitrogen-infused beer reacts with the air, creating a cascading effect and forming a thick and creamy head.
7. Drinking Experience
The drinking experience of Guinness in a bottle versus Guinness in a can can be quite subjective. Some individuals prefer the classic carbonation present in the bottle, which offers a crisp and refreshing taste. Others relish the velvety smoothness provided by the nitrogen-infused Guinness in a can. Ultimately, it comes down to personal preference and what you value most in your Guinness drinking experience.
8. Shelf Life
When it comes to shelf life, Guinness in a can may have a slight advantage. The can’s aluminum packaging offers better protection against light, which can degrade the beer’s quality. However, both Guinness in a bottle and Guinness in a can have relatively long shelf lives if stored properly in a cool and dark place.
9. Availability
Guinness in a bottle and Guinness in a can are widely available in many locations. However, depending on your region or the establishment you visit, you may find that Guinness in one form is more prevalent than the other. It’s always a good idea to check with your local store or pub to see which option is readily accessible to you.
10. Sustainability
From an environmental standpoint, both Guinness in a bottle and Guinness in a can have their pros and cons. Glass bottles can often be recycled, while aluminum cans can also be recycled with ease. It’s important to consider your local recycling infrastructure and choose the option that aligns with your sustainable values.
11. Serving Size
In terms of serving size, Guinness is often available in both bottles and cans in varying volumes. You can find Guinness in bottles ranging from 330ml to 500ml and cans ranging from 330ml to 440ml. The serving size you choose depends on your preferences and the occasion.
12. Travel Convenience
Lastly, when it comes to travel convenience, Guinness in a can often offers a more practical option. The lightweight and portable nature of cans make them easier to transport, whether you are heading to a picnic, a party, or enjoying a drink on the go. Bottles, on the other hand, may be bulkier and more prone to breakage.
