CDR BeerLab® Long Man Brewery – Mash Case Study

Summary of Case Studies CDR BeerLab® Summary of Case Studies Late and dry hopping = IBU value Hops have diastatic activity Increased dry hopping = greater amount of fermentable sugars Secondary fermentation can increase ABV above expected Measurements during the mash process can establish completion/improve efficiency All of the above was done in-house using the BeerLab
