Questions 1.What is Beer? 2.What is the most important reaction during beer making procession? 3.Do you know the components of beer? 问题 啤酒是什么？ 啤酒酿造过程中最重要的反 应是什么？ 您知道啤酒的成份吗？ 4 Whats Beer 什么是啤酒？ 啤酒以大麦芽、酒花、水为主要原料，经酵母发酵作 用酿制而成的，不经蒸馏，饱含二氧化碳的低酒精度 酒。 Generically, beer is any alcoholic beverage produced through the fermentation of starchy materials and which is not distilled after fermentation. 重要的反应叫酿造 This process is called brewing. 酿造是通过发酵获得酒精。由于不同地区所使用的谷 类不同故获得的啤酒的特点也不同，如颜色，气味， 口感。 Brewing is the production of alcohol through fermentation. This reference is mainly used in reference to the production of beer. Because the ingredients used to make beer differ from place to place, the characteristic of beer also differs. As a result, characteristics such as color, smell and taste vary and thus this leads to classification.

Fruit, vegetables, spices and so on are added to both lagers and ales to create different and unique beer with flavors. 这两种啤酒的不同是因为酿造过程的不同，加入的不同的酵母和发酵 环境。如温度和时间。 The difference between the two beverages begins during the brewing process. Whether the beer is a lager or ale is defined by the type of yeast used in the brew and the temperature at which fermentation takes place. 9 Lager 啤酒颜色较淡，口味干，酒精度比Ales低。主要有4种不同的Lager Lager tends to be paler, drier and less alcoholic than ales. There are basically four types of beer that fall under the lager category: 淡Lager通常更多的碳酸饱和，它的颜色更淡，如百威 Pale lager usually contains more carbonation than the other types of beer. It tends to be light in color as well as in body, examples are Coors and Budweiser. 全麦啤酒是另外一种淡色Lager，它有更明显的特点，口味也更苦一点。 All Milt Pilsner is another type of lager that is pale in color. However, pilsners tend to have more distinct flavors and are often more bitter than American style pale lager. 浓色啤酒是由烘培过的麦芽和啤酒花制成，所以具有丰富的口味，颜色也更深。 Dark lagers are made with roasted barley and hops, and therefore have richer flavor, a very dark color and a full-bodied taste. 淡色啤酒 中的啤酒花和大麦含量比较少，所以它的卡里路和酒精含量低使得它更健康。 Light lager beer contains less hops and barleys, which reduces the calorie and alcohol content of the beer making it healthier to consume. Lager 10 Ales; ale, porter from the tap 如何从水龙接啤酒 Select a branded glass to match the beer that has been ordered. 选择合适的酒杯 Check that the glass is cool, clean, unchipped and streak free. 检查杯子是否 凉，干净，无缺口 Handle the bottom half of the glass only the top half belongs to the Guest 拿杯子的底部-杯子的上半部是客人使用的部位 Place the glass under the beer tap at a 45 degree angle to prevent foaming of the beer. 将杯子放在龙头下斜45度角以免杯子充满泡沫。 Ensure the glass does not touch the beer nozzle. 确保杯子没有碰到啤酒龙头口。 Using your free hand, gently pull the tap handle down, releasing the beer stream. 用空着的另一只手打开龙头让啤酒流出。 Keep the glass at a 45 degree angle until glass is half full. 保持杯子45度角倾斜直至杯子半满。 If the beer head at this point is too big (over 2cm) stop the pour and let the beer settle. 如果啤酒沫太多（超过2公分）停止接啤酒让泡沫落下 If the head is acceptable continue the pour in a single motion by bringing the glass to an up right position to finish the pour. 如果沫不多就继续倒满啤酒并直立酒杯 Always present a pint with a 1 2cm head. 总是预留1-2厘米的空 16 How to pour the perfect pint; ale / stout! 如何接黑啤 Select the correct branded glassware to match the drink that has been ordered. 选择正确的杯子。 Always hold the lower part of the glass the top half belongs to the guest and should not be touched by server. 拿杯子的底部-杯子的上半部是客人使用的部位 Check that the glass is cool, clean, unchipped and streak free. 检查杯子是否 凉，干净，无缺口 Hold the glass at a 45 degree angle under the beer nozzle being careful not to let the glass touch the beer nozzle. 将杯子放在龙头下斜45度角以免杯子充满泡沫 开始时要小心不要让被子碰到龙头 Gently pull the handle down to release the flow of beer, Pour product until glass is 3/4 full. 让啤酒流出至被子3/4满处。 Place glass down and let the ale / stout settle in color (approx 1 min). 将杯子放下，并让啤酒静止以便颜色显现。（大约1分钟） Once product has settled, continue pouring until glass is full. 当酒稳定后，继续将被子倒满。 Allow 1-2 cm for the beer head. 杯口允许1-2公分的空间 17 How to pour the perfect pint; from the bottle! 如何倒瓶啤 Do not agitate the bottle this may cause the beer to gush when opening 不要晃动酒瓶，以免开启时泡沫喷出 Always hold the bottle by the shoulder never from the top or the base 拿啤酒瓶的中部，不要拿底部或杯口 Check the beer temperature make sure it is cold! 检查啤酒的温度-确保它是冷的！ Place the neck of the bottle over a clean glass 瓶口放到杯子里 Quickly raise the bottom of the bottle to a high angle - causing the beer to agitate into the bottom of the glass 快速提起瓶子的底部-以使啤酒冲到杯子底部 Lower the bottle to reduce the flow until the head rises to the rim! 慢慢放低杯子降低酒的流动直到酒达到杯边 18 The general causes; 主要的问题： Glasses are not “beer clean Not enough CO2 pressure in the lines Cooler or dispensing system too cold Leak in pressure in the tubing or barrels Loose tap or pressure connections Defective pressure check valve in tap Sluggish pressure regulator Obstruction in line near barrel Air compressor used for pressure Long exposure to air instead of CO2 pressure Pressure required does not correspond to beer temperature (system is not “balanced“) Beer line system is not as cold as beer in the barrel Beer dispensed through small-diameter tubing into large shanks and faucets Beer has pulled incorrectly Beer trouble shooting; flat beer 倒酒时可能遇到的问题 19 Look 一看：* 看酒体色泽 * 看透明度 * 看泡沫 Smell 二闻：闻香气 Tasting 三尝：品尝味道 Beer Tasting 啤酒的品尝 20 Cloudy beer/啤酒混浊 1. Faucets in bad or worn condition 2. Kink, dent, twist or other obstruction in tubing near faucet 3. Beer line system is too long, unrefrigerated or un - insulated 4. Beer warm in barrel and/or in dispensing system 5. Too much pressure (system is not “balanced“) 6. Creeping gauges or increasing pressure 7. Frozen glasses Off tasting beer/味道变质 1 Hot spots in beer lines 2. Beer hose in poor condition 3. Dirty lines 4. Defective pressure check valves, causing contaminated pressure system 5. Contaminated pressure source 6. Beer that has been frozen faucets 7. Old stock 8. Dirty glasses Beer trouble shooting; cloudy keep a log of the check remind employees and delivery men to keep the cool room door closed to minimize temperature loss never stack other items on top of full kegs do not store any food stuff with draft beer check that gas (co2) is constant and uniform in pressure 23 对小桶的扎啤来说温度是最重要的 几乎所有的扎啤问题都是因温度引起的。大部分的扎啤都没有经过杀菌所以它必须冷冻保存。 温度必须保持在1-3度。 即使温度仅比4-5度超出半度，也会使二氧化碳挥发导致啤酒变质和发酸/或混浊。 当温度上升到10-15度，细菌就会大量滋生破坏啤酒的口味。简单来说啤酒的储存和牛奶的相 似“如果不保持冷藏就会坏掉” 处理扎啤时应注意的几点： 每天检查冰箱的温度，并记录在工作日志上 提醒员工和送货人及时关闭冰箱门以保持低温 不要在啤酒桶上存放其他物品 不要同扎啤一同存放食品 check that gas (co2) is constant and uniform in pressure 检查CO2气罐的压力参数保持一致 Draught beer handling: 处理扎啤 24 Cleaning beer lines: 清洁扎啤线 All beer lines regardless of the volume of draught need regular cleaning and rinsing at least once every two weeks. Lines must be cleaned to remove sediment that adheres to the inside of the beer lines. This sediment can cause the beer to taste and smell off. Mix a brewery approved cleaner in a bucket of water according to manufacturers direction Disconnect tap from the barrel and
