Last time, we looked at harvesting and storage of coffee. Today we pick from where we left, and focus on Roasting and blending, and Brewing.
There are different ways to blend coffee. The main differences have to be variance in acidity and taste. Essentially, the process of blending can be summarized as the act of balancing flavors in order to make a superior coffee blend. In a general note, most of the well known coffee blends contain around 5 to 7 types of coffee beans.
It is said that coffee roasting is one of the operations coffee lovers love to do by themselves. In a summary, roasting can be said as the process of balancing addition and reduction of aroma and flavors. The expected results are a dark brown coffee if perfectly roasted and black if not correctly done.
Modern technology has come up with varied ways of roasting, but all rely on the same old concept. This concept is to roast coffee bean to evenly flavorful state. The most popular roasting methods are Drum and Hot air roasting method.
Drum Roasting Method
In this method, machines roast the coffee beans in a rotating drum heated by gas. When it is done, the beans are removed to cool to prevent them from overcooking.
Hot Air Roasting Method
In this method, the beans are roasted on a hot air current.
Green coffee beans are mostly roasted at around 400 degrees Fahrenheit. After going through roasting process, coffee beans usually increase by half but concurrently losing considerable weight.
Mostly beans are roasted at home in an ordinary frying pan. Unfortunately, after roasting, coffee doesn’t keep the aroma for a long time. Therefore, don’t roast more coffee than you can finish in a week or two or you will be force to keep them in jars with well fitted lids in the freezer.
Brewing is one process of making you can either crown or break the final product. This is why even before describing the process, it is important we outline the rules to be observed.
- Always keep the coffee maker clean, and thoroughly rinse it with hot water before brewing
- If you work in an area with hard water or alkaline, once in a while run a strong solution of vinegar in order to clean out deposits of lime on the brewer and rinse thoroughly.
- Always use fresh water, free from alkaline and impurities. Use filtered or bottles water for the best results.
- If possible, brew with hot water rather than boiling or lukewarm water. The fact is, boiling water damages flavor as it vaporizes much of the coffee essence while it extracts other bitter chemicals. A temperature of 200 centigrade’s is good, which means boiling the water and then waiting for a couple of minutes to cool before the brewing.
- Ensure you grind the coffee to the finest as it can get without losing any through the holes in the filter of the coffee maker. Remember; never grind to a powder form.
- Use plenty of coffee, 2 level of tablespoons or at least 1 standard coffee measure per 12- ounce cup.
- In drip and filter systems, avoid brewing less than the brewer’s full capacity. For instance if the pot is made to brew six cups, the coffee will taste if you brew the full six.
These are the most popular methods of brewing:-
Drip Brewing Method
Manual or electronic drip brewing produces better quality coffee by allowing near boiling water to slowly drip through the coffee grounds. Ensure that the water heats to 195 F, therefore a good quality home brewer capable of maintaining the required temperature. You can transfer the brewed coffee to a thermos. For convenience sake, you might consider investing in a high quality drip brewer that drips directly into a thermos.
French Press Brewing Method
This method uses pressure and infusion to create what is mostly termed as “perfect cup of coffee”. In a plunger pot, place the appropriate amounts of coffee into the bottom of the baker and pour in just boiling water. Then allow the coffee to steep for at least 5 minutes – longer for an intense flavor – and throw coffee grounds to the bottom of the beakers.
Espresso Brewing Method
In a stovetop espresso maker, heater water is pushed through a filter containing finely grounded coffee. Afterwards, liquid is deposited into a different chamber where it is ready for consumption. The electric, home use espresso maker is similar to those found in most coffee shops. Hot water is pushed through the coffee grounds under very high pressure creating a heavy, more intense brew.
I hope you appreciate the process of making that cup of coffee you take regularly.
