1. Why was Percy™ developed?
This custom-designed tool was created to provide craft brewers with an easy and efficient pitching method for our 500g and 2.5kg packs.
2. What benefits does Percy™ offer craft brewers?
When used correctly, it helps to maintain the high microbiological quality standard of our active dry yeast (ADY) and reduce any potential cross-contamination that can occur in breweries when pitching yeast into fermentation vessels.
The Percy™ system was designed to make Fermentis packaging easy to open, easy to pierce, and easy to pitch.
3. What are the key benefits for brewers?
The Percy™ tool:
- ensures a more sterile environment when pitching yeast
- minimizes the risks of cross-contamination in breweries
- helps brewers craft their favorite beers consistently
4. How does Percy™ reduce cross-contamination risks?
The Fermentis Percy™ tool and Easy-To-Open packaging were designed to ensure a more sterile handling process, helping brewers maintain the high microbiological quality of Fermentis ADY – from production in our facility all the way to fermentation in your brewery.
Our beer yeast packaging’s Easy-To-Open Target Disc is sealed, ensuring a sterile surface underneath. When pierced with our Percy™ tool (following our best practice guidelines), our ADY can be pitched directly into the work with added control and no risk to fermentation.
5. How does Percy™ help to reduce spoilage in breweries?
Choosing Fermentis active dry yeast guarantees high microbiological quality. Pair this quality with a reduced risk of microbial contamination when pitching, thanks to our Easy-To-Open technology, and you have a winning combination for successful fermentations, every time.
6. How does Percy™ improve fermentation and ensure consistency across batches?
When brewing, maintaining microbiological quality is essential for healthy fermentation and, in turn, a successful beer.
Percy™ makes it easier to maintain the high microbiological quality of Fermentis yeast when pitching. This ensures consistency across batches.
The steady flow of yeast through the Percy™ tool also helps brewers distribute the yeast evenly over the surface of the wort in a controlled manner.
