Think of us as beer doctors – your beer requires regular check-ups, just like you do. Standard beer QC testing typically occurs monthly, quarterly, or per-batch. In order to remain safe, consistent, and professional, adherence to a testing regimen is strongly advised. MaryGold Labs offers an impressive 15% discount on all tests for beers contractually-committed to one of the above testing frequencies, for a 12-month period. Additionally, Committed Customers receive free Yeast Storage (for up to six strains), and free pH and Color tests for the enrolled beers.
