Sodium In Ipa Beer: What's The Deal?

Indian Pale Ale, or IPA, is a popular beer that was first brewed during British colonial times. Sailors needed a beer that would survive long journeys from Britain to India, so they brewed a beer with lots of hops, and the India Pale Ale was born. Today, IPAs come in a variety of styles, including West Coast, New England, British, and Belgian. While IPAs are often associated with high alcohol content, this is not always the case, as session IPAs usually have an alcohol content of less than 5%. In addition to alcohol content, the amount of sodium in beer is also a factor that can affect its taste and flavour. Sodium, or salt, is commonly added to food to accentuate flavour, and it plays a similar role in beer. While sodium is naturally present in brewing water, it can also be added during the brewing process to enhance the sweetness, maltiness, and roastiness of the beer.

IPAs typically contain 14mg of sodium per can

While the exact amount of sodium in an IPA may vary depending on the brand and brewing process, the typical amount of 14mg is consistent with the amount found in regular beer. This amount of sodium is also within the recommended range for darker, full-bodied beer styles like stouts and porters, which tend to have higher sodium levels.

The role of sodium in beer is interesting because it's not just about the direct contribution to the taste, but also how it interacts with other ions. For example, having higher levels of sodium along with sulfate can introduce a harsh and sour taste. Therefore, brewers need to carefully consider the balance of ions when crafting their beer.

Additionally, the source of brewing water can also impact sodium levels. Well water, especially in coastal areas, water treated with softeners, or water treated with sodium metabisulfite to remove chlorine can result in higher sodium concentrations.

While sodium levels in IPAs are generally not a cause for concern in terms of health or taste, it's interesting to note how even small concentrations of sodium can influence the overall character of the beer.

Sodium is added to accentuate sweetness, maltiness, and roastiness

Sodium is added to beer to accentuate its sweetness, maltiness, and roastiness. The taste of sodium is very familiar—from seawater to the seasoning of food with table salt (sodium chloride). When adding table salt to food, the chloride ion is added in almost equal quantities—it's usually regarded as the sodium that does most of the heavy lifting in food flavour.

Brewing water contains a multitude of ions, though the most important six are the three negative anions: alkalinity, sulfate, and chloride; and the positive cations: calcium, magnesium, and sodium. The latter, sodium, is the focus here.

Small amounts of sodium in beer can accentuate its sweetness, maltiness, and roastiness, as well as provide "palate fullness". This makes it more appropriate to use additional sodium in darker, full-bodied styles like stouts and porters. Around 100mg/l in brewing water is recommended for these styles. Beyond 150 mg/l, the flavour can become unpalatable to some, and to most by 200mg/l, where it causes a perceived sourness.

On the lower end, delicate beers like lagers and pilsners benefit from lower levels of sodium, below 50 mg/l. The majority of sodium enters the brewing process through the brewing water, though malt and hops also add very small amounts of sodium.

One can of regular beer contains about 14 mg of sodium. However, it's important to note that beer has a very low content of sodium and that excessive chronic consumption of beer without adequate food intake can lead to hyponatremia, also known as "beer potomania".

Sodium levels in beer vary by style

Beer typically contains around 10-20 mg of sodium per 12 fl oz serving, which is about 4 to 14 mg per 100 ml of beer. However, sodium content can vary depending on the style of beer and the brewing process. For example, craft beers can have up to 170 mg of sodium per 100 ml of beer.

The sodium in beer comes from the salt (NaCl) and sodium bicarbonate (NaHCO3) present in the water used during brewing. While sodium is not added directly to the beer, the quantity present in the water can greatly impact the flavor profile, head retention, and overall stability of the beer. Brewers carefully consider the sodium content to ensure it aligns with the desired flavor characteristics of their craft.

The hardness or softness of water used in brewing is determined by the concentration of calcium and magnesium, while sodium levels primarily affect the mouthfeel and perceived body or fullness of the beer. Beers brewed with soft water tend to have a lighter body and more delicate flavors compared to those brewed with hard water.

Certain beer styles, such as Gose, involve the deliberate addition of salt during the brewing process, resulting in significantly higher sodium levels. These beers are known for their distinctive tangy and salty flavor profile.

The preferred sodium range in beer is generally considered to be 0 to 150 ppm, but it should be lower than 100 ppm if the sulfate content is high. For most beers, a sodium level of 50 ppm or lower is preferable.

Sodium is added to brewing water

Brewing water affects the beer in three ways: it affects the pH of the beer, which in turn affects how the beer flavours are expressed on the palate; it provides seasoning from the sulfate-to-chloride ratio; and it can cause off-flavours from chlorine or contaminants.

The ions in brewing water are the cation (positive) and the anion (negative) components of the minerals dissolved in the water. The principal cations are calcium, magnesium, and sodium. The principal anions are bicarbonate, sulfate, and chloride.

Sodium doesn't contribute to water hardness. In small amounts, it is benign, but at larger concentrations, it can cause the beer to taste minerally or metallic.

The majority of sodium enters the brewing process through the brewing water. Sodium is not known to have any beneficial effects on the mash or fermentation, but it does affect the mouthfeel of the beer. Sodium can be added at any point during the production of beer, not just on brew day.

The recommended level of sodium in brewing water is 0-50 ppm. Certain beer styles, such as Gose, may benefit from higher levels of sodium from table salt. Sodium can also be a nice touch in darker beers like stouts. Table salt (NaCl) and baking soda (Na2CO3) are common ways for homebrewers to boost their sodium levels.

It is important to note that small concentrations of sodium can make big differences in the taste and flavour of beer. Therefore, it is crucial to get an accurate analysis of the sodium content in the brewing water to ensure that the beer has neither too much nor too little sodium.

Sodium is absorbed by yeast during the brewing process

Yeast is a single-celled organism that plays a vital role in the production of all alcoholic beverages, including beer. Yeast performs fermentation to obtain energy by converting sugar into alcohol. During the brewing process, yeast ferments the simple sugars present in the cooled wort to alcohol. In brewing, yeasts are generally classified into two broad categories: Top-fermenting 'ale' yeasts and bottom-fermenting 'lager' yeasts. The yeast strain used can have a significant impact on the overall quality of the beer.

Sodium is one of the six major brewing water ions, along with alkalinity, sulfate, chloride, calcium, and magnesium. It plays an important role in accentuating the sweetness, maltiness, roastiness, and "palate fullness" of the beer. While sodium is a player in the membrane transport and osmoregulation of the yeast cell, only very small amounts are absorbed by the yeast and subsequently removed from the process prior to packaging.

Brewers have long been aware of the importance of minerals in water for the brewing process and the final taste and flavor of beer. Small concentrations of sodium can make big differences in the taste and flavor of beer, so it is important to get a reliable and accurate analysis of the brewing water's sodium content.
