Thanks for the post. It humbly reminds us that it is the yeast that make the beer.
I used to think doing a yeast starter was overkill (Erlenmeyer flasks, stir plates, test tubes, etc.) and an unnecessary expense.
I thought, "What's the difference if I pitch one cell or 100 Billion--it will eventually multiply and ferment the beer and finish the same?"
I was only half right--the FG finishes the same, but it doesn't taste the same.
Use a starter to ensure you have enough healthy yeast to do the job right.
Now, I just need to get my fermentation fridge set up to ensure the yeast have optimal temperatures in which to do their work...
