This is an experiment I conducted a few weeks ago. It examines the effect that the starer original gravity has on yeast growth. Only yeast growth and viability based on methylene blue staining were examined. Experiment Setup For this experiment … Continue reading →

After I conducted the Access to Air and its Effect on Yeast Growth in Starters experiment I also started fermentation tests with that yeast. The tests were designed to stress the yeast during a high gravity wort fermentation that would … Continue reading →

Tonight I was finally able to do cell counts on an experiment that I wanted to do for a while now: “How does the access to air affect yeast growth in starters”. The experiment compared stirred starters capped with airlock, aluminum foil, … Continue reading →

In the Fermentation Test for Starter and Air Access Experiment I showed results that suggested that quantity in yeast growth does not necessarily mean best fermentation performance. I repeated these experiments with a different yeast (WLP 036, Duesseldorf Alt) and … Continue reading →

I’m starting to hit a stride with respect to yeast growth experiments. Last week I posted data on Access to Air and its Effect on Yeast Growth in Starters, this week I have data on the effect of the stir … Continue reading →
