Did not rehydrate Danstar BRY-97 yeast...am I okay?
 
I know, I know...haste makes waste, and I'm afraid that's what I did to 1/3-1/2 of my Danstar BRY-97 yeasties when I forgot to rehydrate them. :drunk: Here's the numbers:

OG: 1.069
Pitching temp: 72 degrees
Batch size:5.5 gallons
Number of packets used: 2
Time pitched: 10:30 EST

Here's the (2) scenarios I am thinking of:

1) Wait it out

2) Rehydrate my 6 grams of Muntons Active Bewing "Emergency Yeast" that's been in the fridge since August. The best used date on the package is 09-2013

Any advice would be greatly appreciated. Also, if I use the Muntons yeast, will it affect my flavor profile? TRUST ME...this will not happen again!!

You're good. I'm sure they'll be happy little critters.

You are fine.

Thanks, all. I figured I was worrying over nothing. I haven't used dry yeast in so long, as I always try to get the smack packs, so I forgot to re-hydrate in my haste. I was just wondering if the yeasties would be stressed, and/or that some might die off. Is this the case?

I just checked the carboy and it a very light krausen is begging to form. Are there any down sides to a long lag in fermentation?

You'll still make beer, not to worry there. However, you are correct in that not re-hydrating is poor practice that will kill up to 1/2 of the yeast cells immediately due to excessive osmotic pressure on the cell walls from the high density wort. If you want to make the best beer possible, re-hydrating dry yeast properly is mandatory.

The possible negatives associated with long lag times are yeast stress from an excessive growth phase, which could lead to off flavors, along with increased time for an infection to take hold before a sach-driven fermentation takes off.

All that said, your beer will probably turn out OK...just not the very best it could be. Lesson learned, we've all been there. :mug:

No issues with long lag time. Don't freak out as this yeast will have a long lag time regardless of your rehydrating or not.

It'll finish quick but will take a bit longer for the krausen to drop, so just be patient.

Thanks for the input, FATC1TY! I literally just found a thread on this yeast this morning and started reading it before work. It does seem like many have had a long lag time before active fermentation with this strain, and that it does finish off quickly.

This was a recipe of Doug's that I had not seen before....Sir Hopsalot...brewed with 6 oz. of Centennial.

I'll definitely be patient, and let it run it's course...one of the many things hombrewing has taught me it patience.

How's the brewing been going? I'm thinking of switching over to all grain the next few months...is the offer to come over and observe a brew day still on the table? I am also thinking of going to HopCity's all grain brewing class. Do you have any experience with it, or know of anyone that has?

I have seen that recipe but I have not brewed it. Sounds good. Centennial is a nice hop.

I haven't brewed much, I was up there Saturday milling some grain for a DIPA.

The offer to come over and brew one day is still there. I'm closing on my house around the end of the month so mid feb ill be back up brewing again. Ill message you and we can make something one day for sure. Maybe a saison or something.

I haven't done any classes before. I hear the hopcity ones are good but there homebrew section is kinda small and I don't know how much they offer in terms of homebrew assistance and knowledge. I'm sure it's good though but I haven't done it myself.
