1 Gallon comparison batche-Whirfloc and Rehydrated Yeast

[Stovetop535]

I have started doing some 1 gallon test batches on my stove. Single base malt and just enough Magnum hops to bring me to about 12 ibu. First two are 2 row and vienna, 2 lbs of grain and just over 8 qts of water for my stovetop brew in a bag approach.

Batch on the left has whirfloc added to it, batch on the right nothing.

Batch on the left had a re-hydrated half packet of s05, batch on the right half a packet sprinkled on top.

You cant tell from the pictures, but the batch without the re-hydrated yeast took a full 24 hours to show visible signs of fermentation. The batch with the re-hydrated yeast took approx 16 hours. I haven't taken any gravity readings yet.

I know people will criticize this saying not everything was controlled for, and you are correct. My goal originally was just a comparison of base malts and I happened to forget the whirfloc so I decided to add it and the re-hydrated yeast for the second round.

Edit--fixed pictures. Please ignore typo in title.

I think it's interesting how the yeast (trüb) settled differently in both.

Interesting test. Not hydrating the yeast reduces its viability, or so I hear, and your test corroborates that nicely.

I love seeing experiments but as you predicted the criticism is changing more than one variable per sample ends up being very inconclusive.

how many whirfloc did you use for the one gallon batch? 1/2 tab?
