Liquid Yeasts

[tazman1967]

Why do my liquid yeasts fang into my AG worts like theres no tommorow...
But on a Partial or KnK they are just happy to chug along merrily ?
Both yeasts are made into starters the same way ?
Just a simple question from an observation Ive had...
Sorry..sounds like a dumb arse question..But Id thought Id put it out there.
Cheers

I would say (and I'm no expert) that the high level of fermentables in the AG make it go harder.

Anyone????

This depends on how you make your all grain.

I think kits have a high amount of dextrins in an attempt to add some body. This means less easy food for the yeast

not 100% sure, but I think its more to do with the levels of non sugar nutrients, eg nitrates, aminos, etc in fresh wort vs processed extract.

An old article about FAN that might shed some light....

NB: Both Wyeast & Whitelabs sell yeast nutrient.

I have also noticed differences in fermentability of extracts.
I am currently using this yeast with "extramalt" from ibrew. One nearly exploded, so I would call that kinda ape.
