FIG. 1 is a flow chart of the preparation process of the hop-fragrant IPA beer provided by the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides a hop aroma IPA beer malt formula, wherein the malt selected in the formula adopts El malt matched with burnt malt, wherein the chroma of the El malt is 6-8EBC, and the chroma of the burnt malt is 50-90 EBC; the content of the Aier malt is 80-90% of the selected malt, and the content of the burnt malt is 10-20% of the selected malt.

The hop-aroma IPA beer provided in the above embodiment is made from whole wheat, and the selected malt mainly comprises El malt, and is matched with burnt malt, wherein the El malt accounts for 80-90% of the content of the selected malt, and the burnt malt accounts for 10-20% of the content of the selected malt; in addition, the beer formula does not need to use rice, corn and other auxiliary materials, the preparation of the flower-fragrance IPA beer also needs to be combined with the specifically limited requirements of the original wort concentration, the alcoholic strength, the chroma, the bitter quality and the like of the beer to prepare the beer which has the characteristics of rich hop fragrance, harmonious hop fragrance and wheat fragrance, bitter taste accompanied with aftertaste and the like, and the problems that the IPA beer prepared by the traditional method has green hop fragrance, covered malt fragrance and the like are solved.

Furthermore, the above examples used ales malt and burnt malt for the reason that: the chromaticity and the wheat flavor of the selected malts are slightly higher than those of the pilsner malts used in common light beer, and the aim is to improve the mellowness of the beer body; the burnt malt is the malt with relatively low chroma, so that the beer color and the wheat flavor are improved, and the excessive burnt flavor of the beer can be avoided; meanwhile, the chromaticity of malt is limited, for example, the chromaticity of the Elmalt is 6-8EBC, wherein the chromaticity of the Elmalt can be selected from 6EBC, 7EBC, 8EBC and other numerical values, or any numerical value in the range; the color of the burnt malt is 50-90EBC, and the color of the burnt malt can be selected from 50EBC, 60EBC, 70EBC, 80EBC or 90EBC, and the like, or any value in the range, and the invention is within the protection scope.

In a preferred embodiment, the prepared hop IPA beer has the hop aroma component content of 200-300 μ g/L and the 2-acetylpyrrole content of the wheat aroma substance of 150-200 μ g/L.

The above examples not only define the relevant parameters for obtaining the beer, but also further define the content of aroma substances and the like for preparing the beer, for example, the content of the hop aroma components is 200-300 μ g/L, wherein the hop aroma components can be selected from values of 200 μ g/L, 220 μ g/L, 240 μ g/L, 250 μ g/L, 270 μ g/L or 300 μ g/L; the content of the wheat flavor substance 2-acetyl pyrrole is 150-200 mu g/L, wherein the content of the wheat flavor substance 2-acetyl pyrrole can be selected from 150 mu g/L, 160 mu g/L, 170 mu g/L, 180 mu g/L, 190 mu g/L, 200 mu g/L and other values, or any value in the range is within the protection scope of the invention. Therefore, the invention is limited in multiple directions from the aspects of raw materials, hop aroma components and the like so as to ensure that the flavor and the mouthfeel of the obtained product can achieve the expected effect.

The embodiment of the invention also provides a method for preparing the hop-aroma IPA beer by using the hop-aroma IPA beer malt formula in the embodiment, which comprises the following steps:

s1: selecting folium Artemisiae Argyi and burnt folium Hordei Germinatus as main raw materials, pulverizing, adding into saccharifying pot, adding water, mixing at a ratio of 1:3-1:4, and saccharifying at 48-68 deg.C for two stages;

s2: after saccharification is finished, heating to 76-80 ℃ after iodine is qualified, and filtering and washing the wort to obtain wort;

s3: boiling the wort, adding hops for 3 times in the boiling process, wherein the addition amounts are respectively 2-4kg/kL, 3-5kg/kL and 6-8kg/kL, carrying out rotary precipitation on the wort after boiling, and adding hops for 2 times in the rotary precipitation process, wherein the addition amounts are respectively 2-4kg/kL and 3-5 kg/kL;

s4: cooling wort, oxygenating into a fermentation tank, adding fermentation yeast with the addition amount of 0.8-1.5kg/kL, and fermenting at the main fermentation temperature of 18-22 ℃;

s5: cooling the fermented liquor to 0 deg.C, cold storing, filtering, bottling, sterilizing, and packaging to obtain the final product.

In the step of boiling the S3 wort, adding three times of hops in the boiling process, wherein the adding amounts are respectively 2-4kg/kL, 3-5kg/kL and 6-8kg/kL, and the hop adding amount in the first time can be 2kg/kL, 3kg/kL or 4 kg/kL; the amount of hops added for the second time can be 3kg/kL, 4kg/kL or 5kg/kL and other numerical values; the third hop addition amount may be 6kg/kL, 7kg/kL or 8kg/kL, or any value within the above range. In addition, the hops are added for 2 times in the rotary precipitation process, the adding amount is 2-4kg/kL and 3-5kg/kL respectively, wherein the content of the hops added for the first time in the rotary precipitation can be selected from the values of 2kg/kL, 3kg/kL or 4kg/kL, and the content of the hops added for the second time in the rotary precipitation can be selected from the values of 3kg/kL, 4kg/kL or 5kg/kL, or any value in the range.

In the above preparation method, 3-6 kinds of hops with special flavor in Europe and America, such as Cascade, Shijikuchu, gold, Barbary, or Simuraceae, etc., are selected by using compound hops addition process. Adding 3 times of flos Lupuli in boiling process, and adding 2 times of flos Lupuli in wort rotary precipitation step; in addition, in the above preferred embodiment, the hops are added at the initial boiling time, the later boiling time of 50-55min and the final boiling time of 60-65min, wherein the later boiling time can be selected from the values of 50min, 51min, 52min, 53min, 54min or 55min, and the final boiling time can be selected from the values of 60min, 61min, 62min, 63min, 64min or 65min, so as to retain the hop aroma substances as much as possible and avoid the influence of the loss of the hop aroma on the flavor and taste of the final beer product; the reason for selecting the main fermentation temperature of 18-22 ℃ for fermentation is that the fruit-flavor ester flavor substances can be generated at the temperature, and the main fermentation temperature can achieve ideal effects by selecting the values of 18 ℃, 19 ℃, 21 ℃ or 22 ℃ and the like.

In a preferred embodiment, the wort boiling step is carried out for 60-65min and the boiling intensity is 7-9%.

In a preferred embodiment, the step of adding hops 3 times in the wort boiling step comprises:

adding flos Lupuli respectively at initial boiling, at later stage of boiling for 50-55min and at final boiling for 60-65 min.
