Wyeast 3203-PC De Bom Sour Blend™

“Wyeast’s QC Manager and World’s Tallest Microbiologist Greg Doss developed De Bom to create authentic Old- and New-World sour ale profiles but in a fraction of the time required by previous, less manly cultures. For best results, we recommend the following: no O2/aeration at beginning of fermentation; periodic dosing with O2 during fermentation to stimulate ethyl acetate production; frequent sampling to monitor development and complexity. Under optimum conditions, beers can be ready for consumption in 1-2 months.”

Vital stats:
