Many friends think that freshly ground coffee represents freshness, but it is not. In fact, in order to drink the aroma of coffee, not only must it be freshly ground, but also the roasting time of the coffee beans must be certain. Front Street, whether it is a store or an online Taobao store, provides freshly roasted coffee beans. Unless the customer requests grinding and delivery, we will grind it according to the customer's usage method (Italian style or manual brewing).
The reason why Front Street places so much emphasis on fresh roasting is because as time goes by, the coffee will basically lose its aroma after it has been roasted for more than 50 days. Some people may ask, is the fresher the coffee, the better? No, in the first two days after it is roasted, its aroma is not very stable, and you cannot taste the flavor of its production area. Therefore, Front Street will remind customers that it usually needs to be brewed for three or four days before brewing.
When FrontStreet Coffee first entered the coffee industry, it was exposed to coffee cultivation. FrontStreet Coffee also has its own coffee plantation. At the same time, it also has its own roasting factory. The roasting goal of FrontStreet Coffee is to reflect theFlavors of coffee producing areas, in fact, everycoffee beans roastingIt can be anything, but FrontStreet Coffee believes that the roasted taste should reflect the taste of the production area. For example, Yirgacheffe should have the taste of Yirgacheffe, and then develop other possibilities on this basis. This is the only standard for FrontStreet Coffee to determine coffee roasting. The second is to ensure the freshness of the roasting. In order to enable customers to drink the best tasting coffee, Front Street only roasts the required amount and does not keep any inventory.
Next, Front Street uses a daily productPanama Janssen Geisha coffee beansFor example, what is the difference between brewing coffee beans that have just passed the bean curing period and those that have been stored for 2 months?
【Front Street Panama Jensen Manor Geisha】
Manor: Johnson Manor
Production area: Woken production area (Volcan）
Variety:GeishaGesha
Treatment method: Sun exposure
Altitude:1750M
Flavor: rose floral, citrus lemon acidity, grape, apple, peach, maple syrup, tea taste
The roasting dates of the Jensen Geisha that Front Street conducted this experiment are [5.27] and [7.21] respectively. One has been raised for 2 months and has no gas emissions; the other has been raised for seven days and has just entered the flavor period.
This Janssen Geisha is lightly roasted. Three water temperatures were tested on Front Street: 92°C, 90°C and 88°C. Other parameters remained the same: V60 filter cup, powder amount 15g, powder-to-water ratio 1:15, grinding degree (No. 20 standard sieve pass rate 80%).
Freshly Baked Janssen Geisha
Steam 30g of water in the front street for 30 seconds, add water to 125g segments, continue to add water to 225g when the water level drops and is about to reveal the powder bed, remove the filter cup when the water level drops and is about to reveal the filter cup, the extraction time is 2 minutes (including the steaming time).
[Brewed flavor at 92°C] It smells of fermentation, has the flavor of lime, raspberry, and nectarine in the mouth, has the sweetness of cocoa, cream, and caramel, has the aftertaste of vanilla and fruity sweetness, and has high mellowness.
[Brewed flavor at 90°C] It smells like jasmine flowers, and has the flavor of citrus, raspberry, strawberry and raspberry in the mouth. It has the sweetness of cream, the taste of tea and the sweetness of caramel.
[Brewed flavor at 88°C] It smells like fermentation, with sour notes of lemon and pomegranate in the mouth, and sweetness from fruit sugar. The aftertaste is sweet from licorice, with a fruity flavor, but with a slight grassy flavor.
Comparing the previous one, you can clearly feel that the one brewed with [water temperature 92℃] is full of sweetness but has a bitter taste at the end, the one brewed with [water temperature 90℃] has a good flavor level, and the one brewed with [water temperature 88℃] tastes good sour and sweet but has a slight grassy taste. Front Street believes that [water temperature 90℃] is more suitable for brewing this Janssen Geisha.
Distance to baking date2Jason Geisha
Front Street brewed this bean at 90°C. Steam with 30g of water for 30 seconds. Add water to 125g segments. When the water level drops and the powder bed is exposed, continue to add water to 225g. When the water level drops and the filter cup is exposed, remove the filter cup. The extraction time is 2 minutes (including the steaming time).
The brewed flavor has citrus, lemon, licorice, and cocoa flavors in the mouth, but with tobacco, woody flavors, miscellaneous flavors, and astringency.
Front Street’s analysis is that the beans have been stored for a long time, and the flavor is lost over time, leaving only the woody flavor. The first flavor substances to be lost are mainly floral and fruity aromas, volatile acids, spices and herbs. Flavors such as nuts, chocolate and caramel are relatively less volatile, so less flavor can be extracted. Brewing with the same parameters as fresh beans will result in over-extraction. So Front Street tried to change the parameters. First, he shortened the steaming time and kept the other parameters the same.
Steam 30g of water in the front street for 15 seconds, add water to 125g segments, continue to add water to 225g when the water level drops and is about to reveal the powder bed, remove the filter cup when the water level drops and is about to reveal the filter cup, the extraction time is 1'40'' (including the steaming time).
Flavor: It smells of fermentation, and tastes sour with berries, strawberries, and citrus. The aftertaste has a light floral aroma and a cocoa flavor, but it has a woody taste and a slightly astringent taste.
Front Street found that although the steaming time was shortened, the flavor would be much better, but there would still be miscellaneous flavors and astringency, so Front Street adjusted the grinding degree to be coarser (the pass rate of No. 20 standard sieve is 72%) to reduce the substances that can be extracted.
Steam with 30g of water for 15 seconds, add water to 125g segments, continue to add water to 225g when the water level drops and is about to reveal the powder bed, remove the filter cup when the water level drops and is about to reveal the filter cup, the extraction time is 1'40'' (including the steaming time).
Flavor: It smells faintly of fermentation, and tastes like lime, citrus, nectarine and nuts. After cooling down, it will have the sweet and sour taste of tamarind cake. The overall flavor will be cleaner and the astringency will be much weaker.
In fact, Front Street feels that the flavor of this pot is quite good, but Front Street is a little curious, what would happen if the water temperature was slightly lowered on this basis? Without further ado, let’s adjust the water temperature to 89°C and keep other parameters unchanged.
Steam with 30g of water for 15 seconds, add water to 125g segments, continue to add water to 225g when the water level drops and is about to reveal the powder bed, remove the filter cup when the water level drops and is about to reveal the filter cup, the extraction time is 1'40'' (including the steaming time).
Flavor: There are flavors of citrus, green apple, berry, and nectarine in the mouth, with a sweet aftertaste of sucrose and an almond aftertaste.
Front Street compared the [Janssen Geisha] that has just passed the bean-growing period and the [Janssen Geisha] that has been stored for 2 months. It is obvious that the [Janssen Geisha] that has just passed the bean-growing period has a clear floral aroma, rich and rich flavor, while the coffee that has been stored for 2 months is easy to over-extract, but the coffee brewed after paying attention to the parameters still has a good citrus and berry flavor.
