A drinking vessel born for beer
Maximize the taste of beer. This beer container was born by looking at the properties of beer.
The love of beer crosses over every barrier, including country borders, genders, lifestyles, scenarios, and generations. While beer is popular among the general public, and it’s readily enjoyable taste is appealing, it truthfully has very delicate properties. Product development at RIVERET starts by knowing the characteristics of beer.
Draft beer, bottled beer, and canned beer have clear differences in taste, even within the same brand. The latter types of beer have greater contact with air during the shipping process, which promotes oxidation and deterioration. The reason that draft beer served in bars and restaurants is considered delicious is that it has almost no contact with air from the brewing process to when it is poured into a container. However, one advantage of bottled and canned beer is that they can be enjoyed at home. How can you freely enjoy the true taste of beer without it being spoiled? Tableware manufacturer RIVERET’s unique point of view will show its true value here.
Beer that has been poured into a beer mug or glass is delicious at first, but the last mouthful is about half as delicious. Many people are probably aware of this difference in taste. There are two main reasons flavor deteriorates: temperature changes due to the open air and oxidation that advances with contact with air. When you drink directly from a bottle or can to prevent oxidation, the beer has too much carbonation, and its sting drowns out the mildness, richness, and sweetness of the beer.
To make bottled or canned beer more delicious at home, you must pour it into a beer mug or glass. Pouring properly cooled beer gently without creating foam itself creates carbonation and forms delicate bubbles. These bubbles provide a cover that prevents the release of aroma and oxidation. The protection from oxidation and the moderate diffusion of carbonation creates the optimal balance of sharp bitterness and full-bodied sweetness.

It is important that beer containers are not easily influenced by the temperature of the open air (by retaining heat well). That’s why RIVERET chose natural material (wood). The thermal conductivity of cedar, maple, cherry, oak, walnut, and various other woods were compared. Cedar and other low-density woods contain more air, so they retain heat well, but they have strength problems. In contrast, maple and other high-density woods retain heat better than glass and porcelain, but it seemed that this property could not be utilized sufficiently.

However, bamboo has high values for both heat retention and strength. Bamboo is said to be a type of grass, not a type of wood. Unlike trees and similar to grasses and leaves, bamboo has straw-like tubes called conducting vessels that are bundled in a straight line. These conducting vessels, which are bundled systematically at the micro level, contain a moderate amount of air but also have more than double the strength of typical wood. From here, RIVERET started development of beer containers made from bamboo.
If you look at a cross-section of bamboo, you can see that a large number of straw-like conducting vessels are arranged. The small amounts of space among these conducting vessels create layers of air, which increase the internal heat retention like a down jacket.
Another question to ask is how can oxidation be delayed? The shape of the drink container is important in maintaining the optimal balance of taste and aroma for a long time. RIVERET is particular about the surface processing of the interior and unique shape lines. Reducing the opening area keeps the aroma in and prevents oxidation. Steepening the slopes near the center of the interior causes the remaining bubbles to move further down. This design allows the cover of bubbles to be maintained as much as possible.
The image shows a comparison of a glass cup and a container by RIVERET after a few sips. A particularly striking difference is the quantity of bubbles that remains on the surface of the beer in the RIVERET container. The interior slopes and manual polishing create a structure in which the bubbles do not stick or stagnate on the sides but flow further down.
(*In the independent opinion of RIVERET.)
Bubbles with a finer texture are more stable and last longer. If the container surface is too rough, bubbles collapse and join to form large bubbles. As a result, they become more likely to break. At the end of RIVERET’s manufacturing process, artisans carefully finish the surface manually. This delicate crafting keeps the fine bubbles created from the beer as unchanged as possible and also promotes proper foaming.
Naturally, materials cause changes in appearance and taste. Nothing may surpass glass when drinking the first sip of beer under the sun in the middle of summer. However, the ability to enjoy the natural taste of beer steadily through all four seasons is a strong point of RIVERET vessels made of natural material.
These vessels were created by RIVERET through research and development according to our unique point of view. They offer different methods of enjoyment depending on the type of beer or setting. Choose an item that RIVERET recommends with confidence and experience the differences in aroma and flavor.
