Participant Beverage Satisfaction (Acceptability)
"How satisfied were you with the beverages you received in this study?" with 5-pt scale response options ranging from "Very Unsatisfied" to "Very Satisfied." Higher scores \[split by condition\] will indicate greater acceptability.
Time frame: Assessed at the end of week 6
Participant Intention to Consume Assigned Beverage in the Future (Acceptability)
"Do you intend to consume the beverage type you received in the future?" with 5-pt scale response options ranging from "Definitely not" to "Definitely." Higher scores \[split by condition\] will indicate greater acceptability.
Time frame: Assessed at the end of week 6
Participant Likelihood of Recommending Beverage (Acceptability)
"Would you recommend the use of the beverage type you received for people who have alcohol use disorder?" with 5-pt scale response options ranging from "Definitely not" to "Definitely." Higher scores \[split by condition\] will indicate greater acceptability.
Time frame: Assessed at the end of week 6
Screened Out of Contacted (Feasibility)
Percentage of participants who completed the screening measure out of those who were contacted. Higher percentage will indicate greater feasibility.
Time frame: Beginning of recruitment to end of recruitment (approximately 3-6 months)
Eligible Out of Screened (Feasibility)
Percentage of participants who screen eligible out of those who were screened. Higher percentage will indicate greater feasibility.
Time frame: Beginning of recruitment to end of recruitment (approximately 3-6 months)
Enrolled Out of Eligible (Feasibility)
Percentage of participants who enrolled out of those who screened eligible. Higher percentage will indicate greater feasibility.

Retention (Feasibility)
Percentage of participants who completed the study out of those who enrolled. Higher percentage \[split by condition\] will indicate greater feasibility.
Time frame: Beginning of recruitment to end of data collection (approximately 3-6 months)
Perception of Beverage Supply (Feasibility)
Percentage of participants whose response to "How was the supply of beverages you received throughout the study?" is "just right" \[as opposed to "too little" or "too much"\]. Higher percentage \[split by condition\] will indicate greater feasibility.
Time frame: Assessed at the end of week 6

Time frame: Baseline to 6 weeks.
Perceived Change in Craving
Percentage of participants endorsing use of study-provided beverages who reported (a) increased in desire to drink alcohol, (b) no change in desire to drink alcohol, (c) decreased desire to drink alcohol \[split by condition\] in response to the item "When I drink the study provided beverages I experience…Less desire to drink alcohol; No change in my desire to drink alcohol; or More desire to drink alcohol.
Time frame: Assessed at 6 weeks.
Perceived Change in Alcohol Use
Percentage of participants endorsing use of study-provided beverages who reported (a) increased in alcohol use, (b) no change in alcohol use, (c) increased alcohol use \[split by condition\] in response to the item "Because I drink the study provided beverages I drink...Less alcohol than I otherwise would; The same amount of alcohol that I otherwise would; or More alcohol than I otherwise would."
Time frame: Assessed at 6 weeks.
Perceived Impact of Beverages on Recovery
Percentage of participants who responded to the item "What impact did the study provided beverages have on your recovery from alcohol use disorder?" with (a) Harmful; (b) No impact; or (c) Helpful \[split by condition\].
