什么是冷啤酒？

冷啤酒是使用冷水而不是热水酿造的咖啡，并在更长的时间内酿造。冷冲泡比普通咖啡强，并且在饮用前经常被稀释。

冷啤酒由于味道光滑，甜味而变得流行，这意味着可以在没有奶精或甜味剂的情况下消费。由于酸度水平较低，许多人喜欢冷酿，这使其更适合任何患有胃酸反流或胃部刺激的人。

Cold brew offers many of the same benefits for your health as regular coffee, including increased energy and alertness, and a decrease in the risk of diseases such as type 2 diabetes, depression, and Parkinson’s.

How is Cold Brew Different Than Regular Coffee?

Cold brew is different from regular coffee because of the way it is prepared. This affects the taste, caffeine content, and acidity levels.

通过在室温水中浸泡地面咖啡的长时间，最多18小时，制备冷水。定期的滴水咖啡是通过将热水倒在咖啡块上，提取时间约为5分钟。

与普通咖啡相比，冷啤酒的味道更平滑，酸度低。用于准备常规咖啡的热水从咖啡豆中提取其他油，这些油可能会引起苦味并增加酸度水平。

与常规咖啡相比，使用标准配方制备时，冷啤酒的咖啡因含量更高。这是因为制备中使用了更多的咖啡豆。与普通咖啡相比，冷冲泡咖啡最多可含有高达500％的咖啡因。

冷冲泡比普通咖啡强吗？

是的，在准备标准配方时，冷啤酒比普通咖啡强。这是因为制备中使用了更多的咖啡豆。

标准recipe for cold brew uses a ratio of 1:5 – one part coffee to 5 parts water. Cold brew prepared in this method contains a caffeine concentration of 518 mg per 8 oz. Regular coffee is commonly prepared using a ratio of 1:17. This results in a caffeine concentration of approximately 175 g per 8 oz.

但是，如果使用相同数量的咖啡豆制备，冷啤酒的咖啡因含量低于常规咖啡的含量约为10％。这是由于热水比冷水更有效地从豆类中提取咖啡因。

How Do You Make Cold Brew Coffees?

您通过将地面咖啡浸入冷水长达18小时来制作冷酿造咖啡。不需要特殊设备，但是您可以购买冷水咖啡机if you want to make drip-style cold brew coffee.

逐步指南如何制作冷冲泡咖啡:

2. 将地面咖啡与五杯水混合在梅森罐子里
3. Stir the grounds well and put the jar in the fridge
4. Leave to steep for 16 hours
5. 用奶酪块或纸过滤器过滤并过滤到干净的罐子中
6. 用水稀释

冷冲泡咖啡有什么好处？

The冷啤酒的好处健康的咖啡与普通咖啡相同。此外，与普通咖啡相比，冷酿咖啡的味道更平滑，酸度较低，对胃的刺激性较小。

冷啤酒的酸度低于普通咖啡，因此引起胃酸反流，胃灼热和消化不良的可能性较小。冷啤酒的味道也可以为您的健康带来好处。由于冷啤酒比普通咖啡较少酸性和苦味较少，因此人们经常在没有糖或奶精的情况下喝它，使其成为更健康的饮料。

Just like regular coffee, cold brew coffee has short-term and long-term benefits for your health. Short-term benefits of drinking coffee include increased energy and alertness, and an improved metabolism. Long-term benefits of drinking coffee include a lower risk of diseases including type 2 diabetes, Alzheimer’s, and Parkinson’s.

Why is Cold Brew Coffee So Popular?

Cold brew is popular due to the taste, the low acidity, and the fact it has a longer shelf life than regular coffee.

Many people enjoy cold brew coffee for the smooth and sweet taste. People find they can drink cold brew coffee without cream or sugar. The lower acidity levels of cold brew, when compared to regular coffee, make it more popular for people who have stomach problems or acid reflux.

Cold brew is stable for much longer periods than regular coffee. Regular coffee should be consumed within 30 minutes of brewing. Cold brew coffee can be stored for 7-10 days in the fridge without affecting the quality. This makes cold brew more convenient.

为什么冷冲泡咖啡如此昂贵？

由于使用的咖啡数量以及准备时间，冷酿咖啡很昂贵。

冷冲泡通常以1：5的比例制备，而定期咖啡的比例为1:17。这意味着冷啤酒使用相同数量的咖啡使用244％的咖啡豆，从而导致食材成本的同等增加。

There is no special equipment needed, but cold brew coffee needs to steep for around 18 hours in the refrigerator. Cafes would need to take this additional time and electricity into consideration when pricing their coffee.

Is Cold Brew Effective For a Coffee?

冷啤酒对于保持清醒的咖啡有效，因为cold brew has more caffeine比普通咖啡。

When prepared with a standard recipe, cold brew contains 64.8 mg of caffeine per fluid ounce. Regular coffee contains 21.9 mg of caffeine per fluid ounce.

但是，与浓缩咖啡相比，冷冲泡不那么有效。浓缩咖啡的咖啡因浓度更高，每盎司含量为77毫克。

这是指用普通咖啡豆制成的冷冲泡。用脱咖啡豆制备的冷冲泡将含有约97％的咖啡因。

购买冷啤酒或制作便宜吗？

It is cheaper to make cold brew rather than buy it from a cafe. This is the case for most coffee drinks.

当您在家制作冷冲泡咖啡时，您只会支付食材的费用。您也可以考虑用于冷藏冷啤酒咖啡的电力成本。

When you buy cold brew coffee, you are paying for more than just ingredients. The cost of the coffee takes into account the ingredients, the wages of the barista, and overheads including rent, electricity, and insurance. The cafe also needs to make a profit, which increases the cost of the drink.

Do You Need Special Coffee Grounds to Make Cold Brew Coffee?

Yes, to make cold brew coffee you need coffee grounds of the correct size: extra coarse. Most prepackaged ground coffee is medium fineness, which is not suitable for making cold brew coffee. To get the correct coffee grounds you will need to grind them yourself using a冷冲泡咖啡研磨机。

由于较长的提取时间，冷冲泡咖啡需要额外的粗咖啡渣。使用较小的磨削尺寸将导致咖啡过度提取，并具有苦味。

但是，您无需使用特殊豆作为冷啤酒。这种酿造方法被认为是非常宽容的，甚至会与较旧的豆一起使用。有些人喜欢使用轻或中等烤冷酿咖啡豆。这些豆子中的天然酸度通过冷冲泡技术降低。

冷冲泡咖啡师可以多次使用吗？

不，冷酿咖啡景不能多次使用。尝试第二次使用相同的咖啡渣将导致冷酿咖啡薄弱且缺乏风味。

咖啡酿造通过使用水从咖啡渣中提取可溶性口味和油。这些口味和油溶于水中以生产咖啡。提取过程后，这些化合物中很少保留在咖啡渣中。

你应该稀释冷啤酒吗？

是的，如果您想要与普通咖啡相似的强度和味道，则应该稀释冷酿，但这不是必需的。冷啤酒在准备工作中使用更多的咖啡豆，比普通咖啡更集中。冷冲泡咖啡的味道更强，含有比普通咖啡高达五倍的咖啡因。

许多人用水，冰块或牛奶稀释冷酿。如果您想以与浓缩咖啡类似的方式消耗冷啤酒，则无需稀释它。

Cold brew concentrate is more concentrated than cold brew coffee and should be diluted before drinking.

您应该等几个小时才能酿造？

您应该等待16-18小时才能酿造冷酿咖啡，但可以让它浸泡长达24小时。

酿造冷水多长时间确实取决于您酿造的温度。在室温下酿造的咖啡比在冰箱中酿造的咖啡更快地提取。对于在室温下酿造的咖啡，请等待16-18小时，然后进行过滤和食用。对于在冰箱中制作的冷酿咖啡，请等待18-20小时，然后进行过滤和食用。在冰箱中酿造的冷冲泡咖啡可以浸泡到24小时，然后再提取。

如果您想要更快的提取时间，则可以使用滴水咖啡系统。这种方法的酿造时间约为8-12小时。

浸泡时应该搅拌冷冲泡吗？

不，浸泡时不应该搅拌冷冲泡咖啡。搅拌会导致咖啡地过早地沉入罐子的底部，从而防止咖啡正确提取。这可能导致薄弱的咖啡。

但是，您应该在酿造过程开始时搅拌冷冲泡。在结合水和咖啡底时，请搅拌均匀，以确保咖啡地面完全饱和。没有搅拌，气泡会减少地面咖啡和水之间的接触，从而导致咖啡不足。

冷冲泡和浓缩冷冲泡有什么区别？

The difference between cold brew and concentrated cold brew is the amount of coffee used in the preparation. Concentrated cold brew contains all of the same components as cold brew but in a more concentrated form.

两者之间的确切差异将取决于所使用的比率，但是标准的冷啤酒食谱为1：5，冷冲泡浓缩液为1：2。在这种情况下，冷冲泡浓缩物将含有两倍的维生素，矿物质和咖啡因作为冷冲泡。

请勿将冷冲泡与冰咖啡混淆，冰咖啡是使用不同的提取方法和不同比例的咖啡与水制备的。有关更多信息，请阅读我们的指南cold brew vs regular iced coffee。

What is the Ratio for Cold Brew?

冷冲泡的比率通常为1：5，尽管有许多不同浓度的冷啤酒的食谱。

标准冷冲泡比is 1:5, meaning that for any amount of coffee you use, you need five times the amount of water. For example, if you use one cup of coffee beans, you will need five cups of water.

但是，冷冲泡咖啡已准备好以个人的味道。对于类似于常规咖啡冷啤酒的较轻品尝啤酒，可以以1：8甚至1:15的比例制备。对于更强大的冷冲泡，建议的比率为1：4。

Cold brew concentrate is brewed at a ratio of 1:2. This is designed to be diluted before drinking.

为什么冷冲泡比热酿造少的酸性？

Cold brew is less acidic than hot brewbecause hot water extracts more of the acidic compound in the coffee beans.

咖啡含有油脂释放奎尼酸,which is responsible for the unpleasant astringent taste and irritation to the stomach. These oils are released from the coffee beans at temperatures over 140°F, and regular coffee is brewed at temperatures between 195°F and 205°F. The cold brew extraction starts with water at room temperature, or approximately 68°F. The remainder of the brewing is done at temperatures under 40°F.

低酸咖啡不一定更健康，但对于患有消化不良，胃灼热或胃酸反流的人来说会更好。
