What're the materials of the brewery equipment?


Whether it's home-brewed beer or professional craft brewery, craft beer is undergoing a renaissance. The true beer rice began to pay for more focus on beer flavor, as opposed to exquisite advertising.


To get a specific flavor, professional and business winemakers spend their time and energy on the selection of raw materials. Use wet hops or dry hops? What sort of malt is useful for brewing?


In every one of these choices, some brewers will go through the brewery equipment as not so important. This is a very dangerous idea. This might not be extremely important with a brewers. But, the metal in brewing tanks, fermentation tanks, and other equipment might have a huge affect flavor. Metals which are difficult to sterilize increase the risk of bacteria in beer. Metals that react easily with wort add a distressing metallic taste. The best raw materials for brewery equipment should be easy to completely clean and not produce other odors.


Stainless has gradually become the standard metal in the brewing industry due to its easy cleaning and excellent corrosion resistance. But it's not the sole option, the brewing equipment can also be made of copper and aluminum. Each metal has its own characteristics and advantages. Even though the stainless steel can be used as a generation material, you will have many differences.


Copper

Before stainless steel entered the market, copper was the metal of choice for manufacturing brewery equipment. Copper has excellent thermal conductivity and can also be a reliable metal for manufacturing brewery equipment. Needless to say, it can also be the easiest metal to manufacture, and you can choose to produce your own custom equipment. But, when the price of stainless steel becomes cheaper, the popularity of copper will drop sharply. At present, most brewery equipment will choose stainless steel whilst the production material.


Copper is not completely inert to beer, but it'll build a stable oxide layer under suitable conditions. Copper with an oxide layer won't bring the metallic taste to the beer (that is, prevent chemical reactions).


Copper can also be easy to completely clean and maintain. You need to use detergent or sodium percarbonate cleaner to completely clean regularly, that may ensure the cleanliness of the copper and the integrity of the oxide layer. But, excessive scrubbing is clearly detrimental to it. A wholesome oxide layer gives the copper a dull and matte surface, and will no longer have a bright or shiny surface.


Also, more oxides aren't better. Copper produces a toxic blue-green oxide, that is called patina. If you see blue-green anywhere on the copper brewing equipment, you will need to scrub thoroughly with vinegar or oxalic acid cleaner. Also, bleach and hydrogen peroxide will blacken the copper and can become unable to prevent corrosion.




Aluminum

Aluminum can be converted to brewing tanks, but it should not be utilized to store beer for a lengthy time. The thermal conductivity of aluminum is half that of copper, but it is preferable to stainless steel. Even though the thermal conductivity is worse than copper. But, aluminum also offers important advantage-under normal brewing conditions, it won't be corroded by beer or add any metallic taste to the beer. If aluminum is exposed to other metals (including copper) for a long time, it'll corrode, and short-term contact is acceptable. Under normal circumstances, brewers using aluminum brewery equipment will choose 3003 or 3004-grade aluminum for their excellent corrosion resistance.


You need to use cleaners which are almost just like copper cleaners to completely clean aluminum. It is preferred to use odorless detergent or percarbonate cleaner. Bleach and other corrosive cleaning agents have been eliminated. The shortcoming to use corrosive cleaners on aluminum is really a problem for professional brewers. Using milder detergents to accomplish more assist inefficient tools, brewers require a quick and effective disinfection method.


stainless steel


The use of stainless steel to manufacture brewery equipment has become a standard in the beer industry, and most homebrewers dream of getting an entire set of stainless steel brewery equipment. The stainless steel brewery equipment is easy to sterilize, inert to beer, corrosion-resistant, and durable.

4 things you might not find out about stainless steel brewery equipment:


Stainless replaced the oldest brewing storage tank, wooden barrel


Stainless tanks need less space than wooden barrels. Because high-pressure scrubbing and disinfection techniques can be used, stainless steel tanks are easier to completely clean and lower maintenance costs. Also, stainless steel tanks can be stated in much bigger sizes than wooden barrels.


During beer brewing, stainless steel can prevent battery corrosion


To start with, we must understand the corrosion of galvanized batteries. When two metals or one metal and contaminants (such as dirt) are extremely close in the electrolyte (such as beer), the current will move across the electrolyte to make a chemical battery with metal whilst the lead. Active metals is going to be ionized consequently, and the ions and oxygen will react with each other to create galvanized corrosion. The conductivity of stainless steel is lower than other metals found in brewing. Also, the corrosion-resistant layer of stainless steel can resist oxidation, thereby preventing galvanic corrosion throughout the brewing process.


All of the brewing equipment is constructed of stainless steel


Previously, copper was used to manufacturing sets from pipes to brewing equipment. Virtually all brewing equipment made of stainless steel is found in brewing. Generally speaking, 304 or 316 stainless steel is going to be selected for manufacturing. Because these two types of stainless steel have good corrosion resistance and perform perfectly in daily brewing. 304 stainless steel is really a cost-effective material. 306 stainless steel has better corrosion resistance and the price is going to be higher. For parts that'll not be exposed to extreme temperatures, 2205 stainless steel is a practical alternative.


Stainless won't produce any odor throughout the brewing process

Because beer is acidic, it's corrosive in tanks and pipes. Also, beer might also contain living microorganisms that may cause corrosion and structure. So, metals are needed to possess good corrosion resistance, and stainless steel is an excellent choice. Stainless has great corrosion resistance, it can stop the abnormal smell created by corrosive electrochemical by-products throughout the brewing process.


Kinds of stainless steel


Stainless is alloy steel with a bright, long-lasting silver finish. The chromium content with this alloy is 11-26%. Also, adding different proportions of nickel can improve toughness, and adding titanium can improve weldability. Currently, there are many types of stainless steel. Many of them are magnetic tool steel, called 400 series stainless steel, but it's not suited to brewing. The stainless steel type used to manufacture stainless steel fermentation tanks and brewing equipment is the non-magnetic 300 series.


Needless to say, there are many types of stainless steel in the 300 series. The most frequent materials useful for brewing are 304 and 316 stainless steel. Probably the most brewery equipment is constructed of these materials. This is because both 304 and 316 stainless steel have great corrosion resistance and are an easy task to weld. The materials used to produce brewery equipment should avoid the usage of other 300 series stainless steel, especially 303. 303 stainless steel has poor corrosion resistance and is a lot more difficult to weld.
