Purpose of lagering tanks

These conditioning tanks clarify and refine the beer's flavours, contributing to the crisp and clean taste associated with lager beers before packaging or serving. This method, utilising bottom-fermenting yeast at cold temperatures, enhances a beer's clarity and flavour profile.

During long-term cold-storage, two significant processes occur: precipitation and aging. Precipitation leads to the settling of solids at the bottom of the storage container, resulting in clearer beer. Meanwhile, aging in cold conditions slows down undesirable chemical reactions, allowing for the development of desired flavours. Additionally, lager yeast tends to ferment a wider range of sugars, resulting in a cleaner, less fruity, and slightly higher alcohol content beer.

In the closed lagering tanks, the beer slowly carbonates as the yeast processes the remaining fermentable sugar. If any oxygen was introduced during the transfer to the lagering tanks, it is possible for yeast to scavenge it during the lagering phase, limiting potential damage to beer flavour and appearance. <insert link to oxygen article>

Efficient beer production is crucial for meeting brewery demand, and our lagering tanks are designed to facilitate this process. Horizontal Lagering Tanks optimize surface area for efficient fermentation and preservation of complex flavours, making them ideal for fruit beers as well. Investing in these containers can significantly enhance brewery operations and output.

PMG’s stacked horizontal lagering tanks design is very flexible and when fabricated, each has the exact support dimensions enabling them to be stacked interchangeably as either the top or bottom tank. Or the customer can This feature offers expanding breweries the flexibility to purchase tanks at different times, with the assurance that new tanks can seamlessly stack atop existing ones, facilitating future growth.
