Recently, many friends have asked about cold brew coffee, so Front Street took this opportunity to talk about "cold brew coffee".
Cold brew coffee is actually different from ordinary hot water brewed coffee. It is a coffee liquid that is soaked in cold water for a long time or extracted from drip coffee powder. Cold brew and ice drip are the most common forms of cold brew coffee. However, some places now also refer to cold brew coffee in a narrow sense as cold brew coffee, distinguishing it from iced drip coffee. This may come from a translation problem. Cold brew coffee is called "Cold Brew Coffee" in English, and ice-drip coffee is called "Cold Drip Coffee" or "Dutch Coffee" in English.
When making Pour over(V60) coffee, we pay great attention to the water temperature, because the temperature of the water directly affects the extraction efficiency of coffee. The extraction efficiency of cold water is very low. If you want to get a cup of coffee with good concentration, you must extend the extraction time. Therefore, cold brew coffee takes a very long time to make, usually 6-8 hours.
The biggest difference between cold brew coffee and hot coffee is that cold brew coffee takes a long time to extract, so there are more water-soluble flavor substances, the taste is richer, and the taste is more mellow. Moreover, the whole process of low-temperature extraction and storage will result in a longer shelf life, which can generally be stored for 3-5 days.
As for what coffee beans are suitable for cold brew coffee? Front Street recommends using medium-light roasted single-origin coffee beans. The cold brew coffee produced will be refreshing and delicious, which is very suitable for summer drinking.
Some friends may want to know whether a certain type of coffee is suitable for cold brew coffee, or they may want Front Street to recommend several coffee beans for ice-drip coffee. In this regard, Front Street can help you clarify the relationship between coffee bean flavor and cold brew coffee, so that you should know more clearly what coffee beans you want.
The flavor description on the coffee bean label is the flavor tasted during cupping. In other words, no matter what extraction method is used, the coffee produced will have the flavor described on the label. Cold brew coffee is a method that can highlight certain characteristics, such as a strong fermented flavor.
Therefore, whether it is used to make Pour over(V60) coffee or cold brewed coffee, you can choose single-origin coffee beans that match the flavor description on the label according to your own taste. The flavor of the coffee beans themselves does not conflict with the cold brewing method.
“If you like a sour and refreshing feeling, you can choose some washed light roasted coffee beans, such as Qian Street Yirgacheffe, Qian Street Guatemala Flower Goddess, Qian Street Kenya; if you like fruity honey and sweetness, you can choose sun-dried, anaerobic light roast coffee beans. Coffee beans, such as Front Street Oiran, Front Street Boulder Manor Blueberry, Front Street Rose Valley; if you like strong fermentation flavor and wine aroma, you can choose Front Street Honduran Sherry, Front Street Lychee Orchid, Front Street Costa Rica Baja, Front Street Mozart, Front Street Columbia Flower Moon Night..."
Can medium-dark roast coffee be used as cold brew coffee? No, it’s just that most people can’t accept iced bitter coffee. Just as no one will voluntarily drink iced Shasha herbal tea, it’s naturally not recommended. Front Street also tasted a cold brew coffee made with medium-roasted Yunnan beans. After being properly stored and refrigerated for the seventh day, it had a mellow taste and a strong fruit wine-like fermentation. It shows that it is not impossible to make cold brew with non-acid coffee, but it is difficult to make delicious cold brew.
The method of making cold brew coffee is also relatively simple. You can make delicious iced coffee by basically mastering a few key parameters. Cold brew is divided into cold brew coffee extracted by immersion and ice-drip coffee extracted by drip filter. The method of making ice-drip coffee has been explained in detail before on Front Street. Friends who are interested can click "here", and I will not go into details again in this article.
The equipment for making cold brew coffee is also very simple. You only need a 600ml container. "You asked if a mineral water bottle is okay?" "Of course, as long as you don't dislike it as unsightly!" The main parameters of cold brew coffee are coffee grinding degree, ratio and time. The coffee grind required for cold brew coffee is finer than that for hand brewing, about the thickness of a No. 20 sieve with a passing rate of 85%.
The ratio of powder to water is generally 1:12, but you can also adjust it according to your own preferences. If calculated based on a 600ml container, approximately 40g of powder requires 480ml of cold water.
It is recommended to control the soaking time between 12-24 hours. The longer the time, the stronger the coffee will be. Just put the coffee powder and water into the bottle, then shake it gently to moisten the coffee powder. Then place it in the refrigerator (5-10 degrees) for 12-24 hours.
Finally, it needs to be filtered. Use filter paper (cloth) to separate the coffee grounds from the coffee liquid before drinking. You can also put it in the refrigerator at low temperature for 4 hours before drinking. This way the aroma will be better. It is recommended to refrigerate it for a while before tasting.
