UJSM type washes (see tried and proven recipes) are very popular and economical washes.
I have done a few with diferant grains and yeasts. here is my limited experiance with the yeasts so far
Bakers yeast-
is widley promoted on the net forums as the ultimate brewers yeast, I have found it very reliable,cheap and easily availible at supermarkets everywhere. Think household brandnames like Edmonds, Tasti etc :think:
Redstar Premium Cuvee wine yeast-
very nice flavours fast ferments availible from a few independent HBS. $3-$4 a small packet but as you reuse the grain bed the yeast keeps going from generation to generation but i have found it starts to stall about gen4-5 for all sorts of possible reasons , Redstar is my favourite yeast for this type of wash :handgestures-thumbupleft:
i beleive EC-118 has similar characteristics to the Redstar above but i have not tried it yet.
Still Spirits Distillery Yeast Whisky with AG 72g-
expensive at $9 a pack HBS owner assured me i would pull all the desirable cogeners from the wash and blah blah blah tried not impressed bread yeast won in a side by side taste test of white dog end product the judges opinion of this yeast- "eww thats Too strong" it might improve with oaking but why bother dumped it all into feints jar at generation 1- IMHO total waste of money. :handgestures-thumbdown:
Yeast is a living organism and as living things may adapt over generations to to their surroundings thus after 4-5 wash generations you may have a yeast strain that is well adapted to its own needs for the conditions in your wash barrel but may not be meeting your needs ie fast ferments, high ABV, taste etc
What I have started doing for UJSM type washes that works well so far is.... at gen 4-5
I tip my hot backset onto the grain bed thus possibly killing off a large amout of the resident adapted yeast population.
add my suger and some new grains and stir
once cooled to 30c i add new yeast thus making the dominant yeast once more the the original strain.
this works for me and resolves the stalling of washes that may otherwise occur.
Any comments or other recommendations for yeasts for UJSM types washes?
