General Questions

An unopened bag of roasted decaf coffee beans can last for up to 2-3 months, less if the beans have been pre-ground for you. The ideal time to enjoy your roasted decaf coffee is 7 or more days after the roast date, as roasted beans experience a 'degassing' phase after they has been roasted, during which carbon dioxide is released from the beans.

The one-way valve that is common in most coffee packaging allows carbon dioxide to be released from the bag, while preventing oxygen and moisture from entering it. Once the degassing phase ends the beans begin absorbing oxygen. This process causes a slow and gradual decline in freshness and aroma.

Personal taste and storage methods will also affect the freshness of decaf coffee beans. Coffee should be stored in an airtight bag or container, out of direct sunlight, in a cool dry area. 

Mountain Water Decaf beans maintain a clean, crisp, and remarkably solid body. A true treasure of the decaf coffee world. The Mountain Water Decaf process is an all natural decaffeination method that bears some similarities with the Swiss Water Process . First, green coffee beans, which are packed with caffeine, are soaked in the crystal clear waters of Mexico's highest mountain, Pico de Orizaba. This removes most of the caffeine from the beans. The water is then put through an elaborate filtration system to clear away 99% of the caffeine from the liquid, whilst retaining all the flavours and aromas. The beans are then soaked in the liquid to infuse the flavours back into the beans. Finally the beans are dried, packaged, and shipped to roasters who apply their own unique roasting methods to create their delicious distinctive flavours.

If you are looking for a healthy, natural, pure decaf coffee, but one that still retains loads of flavour, then Swiss Water® Decaf is for you! Locale Decaf Coffee by Locale is a natural Swiss Water® Decaf. The Swiss Water® Process starts by developing GCE (Green Coffee Extract) from green coffee beans. The GCE includes fresh water and all the solubles found in coffee beans without, you guessed it, caffeine! Next, fresh green coffee seeds that are still brimming with their caffeine content are washed and cleaned. They are also soaked to attain a hydration level ideal for the decaf process. Then, the GCE solution is made to flow around the green coffee beans for 8 to 10 hours. This step usually finds about 99.9% of the caffeine molecules soaked out from the beans and into the GCE solution. Caffeine is then cleansed from the GCE solution with a sophisticated carbon filtering system. That extra caffeine? Burnt away in a special furnace. Now, as the caffeine is burnt away, the GCE solution is purified and can be reused without having to be created again from scratch. The beans are then dried and packaged, ready to be shipped and enjoyed as Swiss Water® Decaf Coffee.

The Sugarcane Decaf process results in a delicious, subtly sweet coffee bean. The process itself begins with (you guessed it), sugarcane! Sugarcane is used to make molasses, which is then fermented to make ethanol. The ethanol is then mixed with acetic acid (vinegar) to create a natural compound called ethyl acetate. Before the compound is applied to the beans, the beans themselves are first steamed at low pressure. This helps the coffee beans swell up and attain the moisture level ideal for caffeine extraction. The coffee beans are soaked in water along with the ethyl acetate. The ethyl acetate then bonds with the naturally occurring salts inside the coffee beans, which extracts the caffeine, resulting in a delicious decaf coffee that is 97% caffeine free.

Natural decaffeination means that the caffeine in a coffee has been removed using all natural processes. The leading natural decaffeination processes currently being used are Swiss Water® Process, Mountain Water Process, Sugarcane Process, and CO2 Process. All our decaf coffees are naturally decaffeinated.

The amount of residual caffeine in decaf coffee depends on the process that was used to decaffeinate the green coffee beans. We have found that the Swiss Water® Process and Mountain Water Process result in a 99% caffeine free coffee, while the Sugarcane Process and CO2 Process result in a 97% caffeine free coffee.

Current Australian Guidelines indicate that "Pregnant or breastfeeding women and children should restrict their caffeine intake."

All decaf coffees on Tasty Decafs have all been decaffeinated using natural decaffeination processes, free of chemicals and additives, and are 97-99% caffeine free.

Caffeine & Health

Although caffeine acts to promote alertness and wakefulness in moderate amounts, too much caffeine can induce various health hazards. Studies have linked too much caffeine consumption to conditions such as high blood pressure [6], inconsistent heart rate [7], anxiety [8], panic disorders [9] , insomnia [10], and bladder instability [11]. For women who has pre-existing bladder problems, consuming even a moderate amount of caffeine may lead to unstable bladder conditions [11].  

Caffeine is associated with a risk of spontaneous abortions. Therefore, pregnant women are advised to limit their caffeine intake [12], [13]. Caffeine is also known to pass into breast milk. Thus, it can cause symptoms such as fussiness and irritability in breastfed infants when breastfeeding mothers consume too much caffeine [14].

Prolonged consumption of caffeine in high doses—more than 500-600mg per day (equivalent to four to seven cups of coffee)—can result in a condition called caffeine dependence [15]. Termination of caffeine intake in such people can result in caffeine withdrawal symptoms including headache, weakness, drowsiness, fatigue and decreased alertness [16]. These symptoms can occur within 12 to 24 hours of withdrawal and can last for about a week.

Caffeine in moderate amounts can make you feel energised, but too much caffeine will cause a host of undesirable side effects. For some people, decaffeinated beverages such as decaf coffee and decaf tea can be a safer option.

Once ingested, caffeine is completely absorbed into the blood from the gut. Caffeine concentration reaches a peak in blood within 1-1.5 hours after consumption [1]. Caffeine dissolves readily in water and lipids making it rapidly distributed throughout the body through body fluids. Caffeine can pass through the blood-brain barrier, cross the placental membrane and pass into the amniotic fluid, and even enter into the fetus [1]. Caffeine is also found in breast milk and semen [1]. Caffeine is metabolized almost completely in the liver and has a relatively long half-life of 3-7 hours [4] . Half life determines how long caffeine is circulating in the body before being completely metabolized. This half life can vary depending on several factors such as age, pregnancy, sex, and smoking habits [4]

Caffeine stimulates the central nervous system through various mechanisms. Caffeine inhibits the action of adenosine, a neurotransmitter that promotes sleep, by binding to adenosine receptors in the brain. In addition, caffeine also promotes the secretion of adrenalin, a hormone that primes the nervous system for “fight or flee” response, thus increasing the alertness. Caffeine also stimulates the release of dopamine, a neurotransmitter affecting the mood [5].

Current Australian Guidelines indicate that "Pregnant or breastfeeding women and children should restrict their caffeine intake."

All decaf coffees on Tasty Decafs have all been decaffeinated using natural decaffeination processes, free of chemicals and additives, and are 97-99% caffeine free.

Decaf coffee is a great tasting alternative for people wanting to reduce their caffeine intake. The benefits of decaf coffee are many, and may include improved sleep, lower cortisol levels which may assist with stress management and anxiety, and a safer alternative for pregnant and breastfeeding mothers.
