Chris White of White Labs says it’s not necessary to wash yeast?

[duelerx]

You don't dry the yeast. You store them in sanitized canning jars. You keep them in dormant live state. Basically, in the food line waiting to be fed.

Drying is for long term storage at an industrial level.

I don't know any home brewer is equiped to dry yeast.

That said dry yeast is too cheap typically to culture. Most people are doing this for very specific strains or big gravity beers.

For centuries Nords have been drying their yeast at homebrew scale, Lars has instructions on how to do it specifically with Kviek: http://www.garshol.priv.no/blog/393.html

Looks like this does not apply to kveik strains.

This is how I figure it:
Wort volume in liters x gravity in Plato=pitch volume in ml. x.75 for ale x 1.5 for lager.
So, for a 5.75 gal lager @ 1.060:
21.75 L x 15º P=326.5 ml slurry x 1.5 for lager = 489.75 ml slurry
Factor in your viability @ 80%: 489.75 x 1.25=612.18 ml

looks like your getting a little 'to much' head! lol (and, does that suck or blow? )

Confused. What do you mean?

Cider head doesn't have staying power like beer! Pun intended. LoL

I mean your statement about the difficult task of drying yeast for brewing purposes.

Kveik stains can indeed just be dried on baking paper at home, but only those kveik strains. For the other strains, your statement would be most certainly correct.

Yep. Drying kveik is a different monster. Safe to say kveik as a whole is a different monster. I've only used Voss and never tried drying it. But a wood kveik ring (or whatever they are) would be neat to have if only for novelty's sake.

afaik, they are not in use any more. They just store their yeast in plastik bottles or dried on baking paper.

I love that idea... Took a beer archeology class and they talked about references to "brew spoons" in medieval literature that were used to initiate fermentation. Probably a similar concept

I see some stuff about them on Milk the Funk, so at least some folks (though perhaps most of em not Norwegian) are using em.

Not my field of expertise though.

That sounds cool. Is that discussed the Kveik Thread where you told me to under-pitch it?

I quoted the one blog and linked to it I think and the author wrote about it there.

I guess it's more of a unpractical thing but somehow looks awesome so people are copying the approach. Nothing wrong with that but I'd prefer the more practical approach.

Thanks!!! This should be nice read tonight.

My local brewery pitches 1 keg full of yeast into a 15bbl fermentor... that’s nowhere near a 20% by volume pitch... thats crazy and generally bad advice IMO. If that were accurate, a brewery with a 100bbl fermentor would need to pitch 40 kegs worth of slurry (20bbl’s).

Islandlizard has given good advice

A general rule of thumb is 2 million cells per milliliter of dense slurry. This is HIGHLY dependent on the density of the slurry though.

I didn't write it , I'm just paraphrasing Ray Daniels book Designing Great Beers, page 118 lower right . The general rule as per Daniels is 2.5 Billion not million per 50 ml of wort, or 20 billion cells with 1 qt of starter, if you'd like to take it up with him, be my guest. Don't shoot the messenger.

I don't have the book in front of me but I think you may have misread what he wrote or what the context of that statement is. Maybe he's referring to the density of cells in a slurry? Or maybe that's referencing the point where over pitching becomes a real danger?

That would result is ~7 trillion cells pitched into 5 gallons of wort. Every other yeast resource and textbook recommends closer to 1 million cells/ml/ degree plato which should be about 200 billion cells.

Drying Kveik is just pouring your yeast cake onto some parchment and waiting. Have made 2 batches now with dried yeast and happy with outcome.

Hey if you are ever interested in a Kveik Ring i make them and ship worldwide.
