Default What is Pacman supposed to taste like?

So I have used Pacman in two different brews, both american pale ales of different recipes. The first came out tasting very sour and kinda like spoiled milk. This led me to think it was a lactose infection. I sanitized with bleach, then acid, then cleaned with PBW, then sanitized with starsan. I have made 4 good brews since using pacman, all with the same equipment. Recently I decided to use Pacman again in a very simple recipe. Same exact taste in the outcome!! What the heck is going on? People rave about pacman but to me it tastes like spoiled milk.

Everyone likes it because its got a very low flavor profile and its high alcohol tolerance. It makes a good house strain, maybe your problem is something else

i doubt it is the pacman. rogue brewery uses it as a house yeast, and none of their beers taste like sour milk. where are you getting it from?

a 'sour milk' flavor really seems like an infection. you may be harboring an infection somewhere in your system. hard to say where. if it were me, and it keeps happening, i would replace my plastic equipment, and/or really review my sanitation and cleaning practices

Similar to American Ale II in my opinion. Used it before without the results you've had.

I'm guessing your yeast culture got infected somewhere along the way, especially if you harvested it from a bottle.

How are you harvesting the yeast? It is possible that there is a problem with your process? We need a little more info please.

Default PacMan Taste...

PacMan is a very neutral yeast so there should not be any "taste" at all other than the hops and malt of the style/recipe.

I have brewed dozens of pilot batches using PM and have never encountered a sour milk taste or any real taste for that matter.

Re: PM being similar to AA2 - I disagree. AA2 is much frutier than PM not to mention the Chico strain. I love AA2 and use it often but it is a lot different than PM.

I agree that it doesn't taste like AA2 (my favorite for american ales). It is more attenuative and, when fermenting on the cool side, is very neutral. I actually feel like it kind of accentuates the flavor of the mineral content of your water but that could just be me.
When fermented warm pacman supposedly gives off some British yeast flavors, still not like AA2, though.

agreed! I love PM but this added mineral flavor has come through both times I've used it, in one case so much so that it takes the edge off of my hop profile. Guess it's time for a water profile report...

Wait. You're not talking about beer, right?
You're talking about beer. That could have been a whole lot more fun.
