IPA and Yeast

[popquizkid]

As if there isn't enough contention already going on this thread, I'm gonna throw this out there too.

Brew Like a Monk talks about how some trappist breweries will purposely "underpitch" to get the ester character that they want. I believe this is also done with consideration to how much O2 they are or are not adding to their wort.

I have read this as well. But the trappist breweries are most definitely not trying to create IPAs with a very "clean" fermentation profile.

Good info, rwing. I was wondering how you would know the production date when all that is listed is the expiration date. The US-05 yeast that I have at home, I believe expires on June, 2017. That being the case, the production date would be June, 2015? If so, that would take the needed amount of yeast for a 1.070 OG from 1.2 to 1.4 packets.

Also, if I use half a packet of yeast, is there a better way of storing the leftover yeast than putting in a zip-lock bag?

That is the exact same time stamp I had on my US05 packet. Since they don't provide a day I used June 1st for my production date as this is the worst case.

For storage I follow what Fermentis suggests for open sachets- Air tight container with a 7 day shelf life when stored at 39 degrees F. What I have done in the past with no issues is when I use a partial sachet that I plan to use in the near future I fold the open sachet on itself and place in a small pyrex container with lid and place in my refrigerator. If I don't plan to brew within the next 7 days or if I have a beer that only requires 1 sachet I just throw the open sachet away,.

Makes sense on all accounts. I will plan to brew my two higher gravity brew kits, that will need 1 1/2 packets, on consecutive weekends so that I can get away with just using a total of three packets.

That's exactly what I did with my IPA and Stout. I brewed the IPA last weekend and the Stout yesterday.

Very true. Just thought I'd throw a little fuel on this fire.

 

[Nicknack]

Good to know and no worries - no fire here (at least for now). Back to a civil discussion.

I was thinking yesterday about ordering a Stone IPA clone kit. However, I saw in the directions that it uses liquid yeast. Based on what I've read on this thread (and other places on the forum) the reason they use liquid yeast is for a unique flavor profile outside of something like US-05, correct? This is an example where dry yeast can be limited at times, yes?

The instructions indicate that they use White Labs WLP001. Since I only have two batches under my belt, I would like to keep to dry yeast for now so I don't have to mess around with making a starter. That being the case, is there a dry yeast substitute that comes close to WLP001? I don't mind if the clone is slightly different than the original, as long as it is similar. I like the west coast, dry IPA style which is why I was thinking about getting the Stone beer kit.

 

[Nicknack]

I may have found my answer. According to the vendor's website for US-05:

"This strain is very close to Wyeast 1056 and White Labs WLP001 and can be used as a substitute."

That being the case, it looks like I could probably just have them substitute WLP001 for US-05 and I should be fine based on this info and the chart that I found here. The chart isn't an exhaustive list, but it does include some good info that others might find useful as I did.

Now if I could only find a dry yeast substitute for WLP810.

 

[kombat]

Wyeast 1056 "American Ale," White Labs WLP001 "California Ale," and US-05 are all basically the "Chico" strain of yeast. They're effectively the same. You'll be fine using US-05. Just make sure you rehydrate it first, according to the manufacturer's instructions.

 

[m00ps]

OH NO YOU DIDNT!

dont you go steering this thread into dry vs rehydrated territory

 

[Nicknack]

Yeah, the nerve of some people.

Ahhhh... my doorbell just rung and it's my Northern Brewer order (a second fermenting bottle - big mouth bubbler). Looks like I'm brewing that Double IPA tomorrow! :rockin:

For some reason I thought Stone used WLP007. Either way I would not hesitate to use s05 in this beer.

 

[PeteNMA]

Stone use a proprietary yeast strain, but recommend WLP007 as a close commercially available substitute.

If you don't want to use liquid yeast then US05 is the dry equivalent to WLP001 or Wyeast 1056

Now if I could only find a dry yeast substitute for WLP810.
