Craft brewery tanks are a key equipment used in beer production in micro and craft breweries.
Craft breweries are a vital part of the American economy, contributing billions of dollars in revenue and creating thousands of jobs. In recent years, the craft beer industry has experienced explosive growth, with new breweries opening up all over the country.
One of the most important pieces of equipment for any craft brewery is the fermentation tank. Tanks are used to store and ferment the wort, which is the liquid that is eventually converted into beer.
There are many different types of fermentation tanks available, each with its own advantages and disadvantages. In this guide, we will discuss the different types of tanks, as well as the factors to consider when choosing a tank for your brewery.
Types of Craft Brewery Tanks
Fermentation, that ancient magic that transforms simple sugars into delicious wines, bubbly beers, and tangy yogurts, relies on a crucial player: the fermentation tank. But these vessels are far from uniform; they come in a surprising variety, each suited to specific needs and offering unique advantages. Let’s delve into the fascinating world of fermentation tanks and explore the diverse options that shape our fermented favorites.
Open-Top Tanks: A Breath of Tradition
Imagine large wooden vats or ceramic crocks, their surfaces teeming with frothy activity. These are open-top tanks, the most traditional option, offering a direct connection to the environment. This allows for natural airflow and temperature fluctuations, mimicking the open-air methods of yore. While these tanks favor spontaneous fermentation and lend a rustic character to certain products, they require careful monitoring and are susceptible to contamination.
Closed Tanks: Tight Control for Consistent Results
For precise control and hygiene, closed tanks reign supreme. Made from stainless steel or even concrete, these vessels seal the fermentation process, allowing for strict temperature and pressure regulation. This creates a predictable environment, ideal for large-scale production and replicating consistent flavor profiles. Closed tanks often feature conical bottoms, facilitating the collection of spent yeast (trub) and promoting clarity in the final product.
The Hybrid Hero: Unitanks, Efficiency Personified
Unitanks, as the name suggests, are all-in-one wonders. Combining fermentation, conditioning, and carbonation in a single vessel, they streamline the brewing process and save space. This efficiency makes them popular in craft breweries and cideries, allowing for experimentation and small-batch production. However, their versatility comes at a cost, as they require specialized cleaning procedures and may not be suitable for products with longer fermentation times.
Beyond Metal and Wood: Exploring Alternative Materials
While stainless steel and wood dominate the scene, other materials offer intriguing possibilities. Glass carboys, reminiscent of science lab beakers, provide excellent visibility for monitoring fermentation. Plastic tanks, lightweight and affordable, are popular for homebrewing and small-scale operations. And then there are the intriguing ceramic vessels, used for specialty products like sake, adding a touch of earthiness and tradition to the fermentation process.
