Today I got a email from Wyeast about 3787 Trappist high gravity. i thought I would share.
What I wrote:
Yesterday I pitched a starter of 3787 Trappist high gravity into a 5 gallon batch of beer I fear may be to big for it now. I stepped it up with 2, 2 liter starters for approximately 300 billion cells. My expected original gravity was 1.072 but I ended up with 1.090. While that wouldn't worry me I still plan to add 4 more pounds of sugar for about a 36 point increase in gravity. I plan to add this along with another dose of energizer and nutrient when the wort hits 1.040. This will take the beer to about 14% abv. This yeast is advertised to tolerate 12%+, how much + is there? Can it hit 14%?
The answer:
I think you can hit 14%, but you should probably make another starter to add at about the same time you dose the extra sugar. This would be your best bet for a smooth fermentation.
It just so happens I did an experiment to see if I could grow the yeast that was stuck to the sides of the flask after pitching it. I used a 1 liter 1.020 starter that I let run for 2 days until it was finished. then stepped it up with a 2 liter starter that finished today. I now have a 1/2" layer of yeast that i'm going to pitch tonight. After I pitch it I'm going to do the same process and step it back up so I still have some, so far I'm loving this yeast. It floculates faster and harder than any other yeast I have ever seen.
