Software tuning of recipes for beer brewing system
A beer making system may modify a beer ingredient/process recipe to adjust sensory characteristics of a desired beer. With a given ingredient list and starting recipe, a performance model of a brewing system may be used to generate an updated recipe when given a set of desired sensory characteristics of a desired beer. A user interface may permit a user to adjust characteristics such as thin/thick mouthfeel, dryness/maltiness, hops bitterness, hops flavor, hops aroma, and other characteristics. An updated recipe may change mashing schedules, boiling schedules, or other programmatically controlled aspects of a brewing system. The performance model may include heuristics as well as performance metrics derived from observing previous brewing sessions on one or multiple devices.
1. A system comprising:
a hardware platform comprising a computer processor, said hardware platform being connected to a storage mechanism; a control system executing on said hardware platform configured to:
receive a performance model of a computer controlled beer brewing system, said performance model comprising a flavor prediction model based on mashing schedules; determine a first recipe, said first recipe having a first set of ingredients and a first mashing schedule;
calculate a first set of flavor characteristics for said first recipe using said performance model, said first set of flavor characteristics being based on a first mashing schedule, said first mashing schedule comprising a first temperature versus time curve for mashing grains;
receive a first user input to adjust a first flavor characteristic; calculate a change to said first mashing schedule to a second mashing schedule and determining a second set of flavor characteristics for said second mashing schedule, said change being calculated using said performance model and said change being made to achieve said first flavor characteristic; store said second mashing schedule as a second recipe for said computer controlled beer brewing system;
transmit said second mashing schedule in a machine readable format to said computer controlled beer brewing system such that said computer controlled beer brewing system can execute said second mashing schedule, and
wherein said first flavor characteristic being mouthfeel,
wherein said first mashing schedule comprising a first hold time at a first mash temperature and a second hold time at a second mash temperature, said first mash temperature being higher than said second mash temperature, when said first user input indicates decreasing mouthfeel, said second mashing schedule being adjusted by increasing mash time at said second mash temperature to increase beta amylase extraction.
2. The system of claim 1 , said first mashing schedule comprising a first
hold time at a first mash temperature and a second hold time at a second mash temperature, said first mash temperature being higher than said second mash temperature, when said first
user input indicates increasing mouthfeel, said second mashing schedule being adjusted by increasing mash time at said first mash temperature to increase alpha amylase extraction.
3. The system of claim 1 , said control system further configured to:
determine an expected final gravity measurement for said second mashing schedule from said performance model;
receive a measured final gravity measurement after said second mashing schedule has been executed;
determining an error being a difference between said expected final gravity measurement and said measured final gravity measurement; and update said performance model based on said error.
4. The system of claim 3 , said control system further configured to:
collect a plurality of errors from a plurality of measured final gravity measurements, each of said plurality of measured final gravity measurements being taken for a different second mashing schedule; and
update said performance model based on said plurality of errors.
