There are many ways to brew coffee, the most common one is Pour over(V60) coffee, but there are many small details to pay attention to when brewing coffee by hand. Today Front Street will introduce to you a relatively simple coffee brewing method.
Everyone knows that Pour over(V60) coffee is brewed with hot water, but sometimes you want to have a cup of iced coffee to reflect the cool feeling, so you need a cup of iced coffee. Front Street said that the coffee brewing water temperature is different, and the flavor of the coffee is obviously different. The flavor of coffee brewed with hot water will change as the water temperature changes. However, if the operation is not done properly, some bad flavors may also be brewed. The coffee brewed at low water temperature will have a cleaner and brighter flavor, without some of the bad taste brewed at high water temperature.
what isIce drip coffee
Ice drip coffeeOriginating from Europe, because the coffee distiller was invented by the Dutch, some people call it Dutch Coffee, espresso or drip coffee. Ice-drip coffee relies on the compatibility of coffee itself with water, mainly due to the natural osmosis water pressure of condensation. It is extracted bit by bit for about 8 hours. It is a kind of coffee that takes time to brew. The taste of coffee brewed with different water temperatures will be different, and the astringent substances in coffee are not easily dissolved at low temperatures. Use ice water to extract for a long time, and after the extraction is completed, put it in the refrigerator for fermentation. The slightly fermented ice-drip coffee will have a light fermentation aroma and will have a thicker taste. Front Street thinks: You can put coffee in the refrigerator at night and drink it the next morning, and you will wake up instantly! Isn’t that feeling so good?
Some people may ask Front Street: Why can ice-drip coffee be kept for so long without going bad?
The operation time of Pour over(V60) coffee only takes a few minutes to complete, while ice-drip coffee takes more than several hours to complete. However, after brewing Pour over(V60) coffee, Front Street will prompt you to drink the coffee as soon as possible, because the shelf life of hot water brewed coffee is very short, and the taste will begin to deteriorate if left for more than 45 minutes. Because ice-drip coffee does not undergo a heating process and is extracted for a long time, many flavor molecules are extracted, but they are not released well. Therefore, after the ice-drip coffee is extracted, put it in a sealed bottle and put it in the refrigerator for 12-24 hours, which will cause the pressure of carbon dioxide in the bottle to release the flavor molecules. This is why the longer the ice-drip coffee is left in the refrigerator, the richer it will taste.
Of course, Front Street does not recommend keeping ice drops for a week. After all, there are bacteria in the air or bottles, and it is difficult to ensure the condition of the coffee after being left for a long time. It is recommended that the drinking period of ice drops be within 72 hours. Do not think that ice drops are wasted after 72 hours. It is useless to drink coffee that has been left for such a long time.
Front Street tells you: Ice-drip coffee has another advantage! This is good news for people who have a bad stomach and want to drink coffee. FrontStreet Coffee usually recommends iced drip coffee to them. Because many people with bad gastrointestinal problems will stay away from coffee because of the stomach pain caused by ordinary coffee. Ice-drip coffee lacks many of the stimulating molecules found in hot-extracted coffee, and the caffeine content at the same concentration is also lower, making it a healthier choice.
cold brew coffee
cold brew coffeeUsually refers to cold brew coffee, which is obtained by adding an appropriate amount of coffee powder to cold water and extracting it at low temperature for a long time. It was the Dutch who first came up with the cold brew method, and it was later spread to Japan. At that time, the Dutch would ship coffee back to Europe from colonial Indonesia. Because there was no hot water on the ship, they invented the cold brew coffee method. Interestingly, people at the time thought that cold coffee was milder and less stomach-irritating, but they didn’t know that this was because hot water would extract more of the acidic substances in the coffee, while cold-brewed coffee was less acidic in comparison.
cold brew coffeeIt is made with water at room temperature or lower. The water temperature is usually lower than room temperature, around 20-22°C. Due to the low water temperature, the coffee making process is very long, usually taking 12-48 hours, which is longer than ice-drip coffee. Cold extraction can only extract some small molecular substances, such as floral and fruity flavor substances, while the large molecular flavor substances of smoked roasting are not easy to extract, and the sourness will be reduced a lot. However, the most fatal thing about this extraction method is that it has a weak ability and requires a longer period of contact between water and coffee powder.
Someone may ask Front Street: Apart from the difference in time, what are the differences between ice-drip coffee and cold-brew coffee, which are both coffee brewed at low water temperatures? What are the differences in taste?
Front Street believes that iced drip coffee is also a type of cold brew coffee in theory, but there are a few differences:
1. Different extraction methods
Cold brew is an immersion type, where the coffee powder is put into cold water, soaked statically for 16-20 hours, and then filtered into coffee liquid using filter paper; ice dripping is a percolation type, where cold water is slowly dripped into the coffee powder and directly passes through the filter paper to form coffee liquid.
2. Different flavors
The taste of cold brew is very thick, it has the feeling of concentrated concentration, and the flavor is very strong. Unless it is filtered many times, cold brew will always leave some sediment; the taste of ice drop is very light, even close to tea, the flavor is very clean, the floral and fruity aroma is fully released, and there is less bitterness and acidity.
Therefore, Front Street believes that the flavors of the front, middle, and back portions of ice-drip coffee extraction are completely different. The coffee extracted in this way has a bright and layered taste like a fresh one. Although it usually only takes 5-8 hours to make ice-drip coffee, you can put the prepared coffee in a odor-free refrigerator and let it develop stably overnight, and you will get an unexpected aroma.
3. Different production tools
Cold brew does not have many requirements for production equipment; ice dripping generally uses an ice dripping pot. As for someone asking about cold brew coffee andIce drip coffeeWhich one tastes better? In fact, Front Street believes that both taste good. Cold brew coffee is richer, while iced drip coffee is brighter and layered. Everyone has different tastes, so it depends on what you like!
FrontStreet Coffee brewing suggestions:
When brewing any kind of coffee, Front Street believes that the freshness of the coffee beans is a very important aspect if you want the coffee to taste good. Because the freshness of the coffee beans can maximize the rich flavor of the coffee. The coffee beans shipped by FrontStreet Coffee are all roasted within 5 days, because FrontStreet knows that the freshness of coffee beans has a great impact on the flavor. The purpose of Front Street Roasting is "freshly roasted and good coffee", so that every customer who orders receives the freshest coffee. The bean-growing period of coffee is about 4-7 days, so the flavor is at its best when customers get it.
Of course, there are also some customers who need help from Front Street in grinding the powder, which is okay, but Front Street would like to remind you that if the coffee beans have been ground in advance, they need to be brewed in time. If they have been ground into coffee powder, there is no need to grow the beans, because during the transportation process, the pressure generated by the carbon dioxide in the packaging can also make the coffee flavor mellow, so you can brew it as soon as you receive the coffee powder. Since coffee powder oxidizes quickly when exposed to air, which means that the flavor of the coffee will dissipate relatively quickly, and the flavor of the coffee will not be as good. Therefore, Front Street recommends buying whole beans and grinding them freshly, so that you can better taste the flavor of the coffee.
