[PERMITTED_REACTION:BREW_MEATS] or whatever you name your reaction.
You can create a custom alcohol for your brewed meat if you like. Easiest method would probably be to go into the material_template_default.txt and copy and paste the template for CREATURE_ALCOHOL_TEMPLATE. Give it a new token, like MEAT_ALCOHOL_TEMPLATE, and change the material names to something flavorful.
Personally, if I were to do this, these are the steps I would take. Meat into Blood, Blood into Bloodwine (Kaplah!)
1) Copy and paste CREATURE_ALCOHOL_TEMPLATE in the material_template_default raw. Change the name to BLOOD_ALCOHOL_TEMPLATE, and change the state names to bloodwine.

2) While you have the material_template_default file open, locate the MUSCLE_TEMPLATE material template. It should be close to the beginning of the file. Add a material reaction product token to it to direct muscle to form blood. It should look something like this.
[MATERIAL_REACTION_PRODUCT:BLOOD_MAT:LOCAL_CREATURE_MAT:BLOOD]
3) While you have the material_template_default file open, locate the BLOOD_TEMPLATE material template. Add a material reaction product token to it to direct blood to form bloodwine. It should look something like this>
[MATERIAL_REACTION_PRODUCT:BREW_BLOOD_MAT:LOCAL_CREATURE_MAT:BLOOD_ALCOHOL]
3) Open the file b_detail_plan_default.txt raw file. At the top is BODY_DETAIL_PLAN:STANDARD_MATERIALS. Add a BLOOD_ALCOHOL material to the list. Do the same to the BODY_DETAIL_PLAN:CHITIN_MATERIALS for good measure.
[ADD_MATERIAL:BLOOD_ALCOHOL:BLOOD_ALCOHOL_TEMPLATE]
4) Add two new reactions to allow extracting blood and brewing blood into wine. Easiest place is in the reaction_other.txt file. Open reaction_other.txt and add the following reactions at the bottom of the file.
[REACTION:RENDER_BLOOD]
[NAME:render blood from meat]
[BUILDING:KITCHEN:NONE]
[REAGENT:meat:1:NONE:NONE:NONE:NONE]

[PRODUCT_TO_CONTAINER:blood container]
[PRODUCT_DIMENSION:150]
[SKILL:BREWING]
5) Open the entity_default.txt file. At the very top should be the entry for ENTITY:MOUNTAIN. This is the entity for dwarves. Scroll down until you see the tokens for PERMITTED_REACTION. Add the following to the list
[PERMITTED_REACTION:RENDER_BLOOD]
[PERMITTED_REACTION:MAKE_BLOOD_ALCOHOL]
And then generate a new world. You should now be able to extract blood from meat, and brew that blood into bloodwine. Bonus points for you if you can figure out other fun uses for the blood (yum yum blood pudding).
