liquid yeast vs. dry yeast

[azazel1024]

Slurry is dirty. Unless you're super piss poor or work on a large scale and have a way to microbiologically monitor it, dump that crap and grow up a 7$ packet. Acid washing doesn't help wild yeast infections, only bacteria.

Its worked fine for me and thousands of other homebrewers. Also brewers for thousands of years, since that is how brewing used to be done until the last century or so.

Brulospher did a fun test where he tried using slurry vs newly cultured starter from a vial and found that there was no statistical difference in flavor.

Sure, after a few dozen batches it is possible continuously reusing slurry might lead to adverse mutations in the strain eventually, and using a BUNCH of stout slurry in a blonde ale might lead to some darkening of the wort, or using a DIPA slurry in a light wheat beer might lead to a a bit more bitterness than you'd want. So long as you are brewing vaguely within style, the impact of using slurry versus "fresh yeast" from a starter should be minimal.

Now if you rack on top of the yeast cake time after time, eventually you ARE going to impact something, because you are going to have a massive amount of trub in there after a couple of batches. Pitching a reasonable amount of slurry batch after batch isn't too likely to cause any issues.

This is the resulting stout made from the crappy dirty slurry.

OG 1.055. FG 1.017. Three days to ferment.

That blonde ale looks like it turned out horrible. Look at how much the slurry darkened the beer!!!!

The lighting is terrible. The flash didn't capture the golden effervescence and ethereal quality of the head, the bubbles dancing their way to freedom at the surface. Almost magical.

Dangit, now I really want a beer.

I also really want to keep my job, so I am thinking I'll have to wait a few more hours.

Rehydrating dry yeast is like multiple orders of magnitude a cleaner process than washing n repitching used yeast. There's no question, I don't care how sanitary you think you are.

And yet somehow, I still manage to brew delicious, award-winning beers using dirty, filthy slurry collected directly from a carboy into sanitized Mason jars.

It's baffling.

Challenge accepted. Send me a bottle of your delicious dirty beer. I'll do a BJCP sheet on it (I'm certified - #D1320) then I'll filter it and plate on WLD and UBA medias and see what grows. PM and you can have my address. Non-biased results to be posted in detail here.

You guys are getting trolled hard here by a guy on a motorbike.

certainly try a liquid yeast, and decide for yourself.

I like the smack packs for liquid yeast. Just smack it and let it set till it blows up. Instant starter. That's not to say i don't use dry. I do. Just whatever i feel like for whatever beer. I usually just follow the package direction for dry, and 20 minutes is a nice starter for 5 gallons
