    i recently brewed my first doppel and i used the wyeast smack pack and did a yeast starter, it's undergoing active fermentation but after i rack to my secondary fermenter my directions say to add another yeast before i bottle. is this really necessary? any info would be helpful, i cant find too awful much info on this type of brewing... its my first strong lager.

    How long are you planning to let it sit in the secondary? The directions are suggesting this because they presume that there won't be enough viable yeast left for bottling (due to extended aging). I don't do a lot of extended aging so I can't offer much first hand advice about what aging times need/don't need re-yeasting.

    If you do decide to re-pitch be careful about overpitching bottling yeast. You don't need much. Jamil suggests 1 million cells per mL.

    edit: you might want to move this over to the homebrew forum

    im planning on letting it sit in secondary for about 4 months since it says about 6 months total time, i have acquired a mini fridge for lagering so i hope it turns out. i've only ever bottled with dextrose but since it says using yeast as well im a bit confused. thank you for replying dave its appreciated

    I don't know how to do it, but your question should be in the homebrewing forum.

    After four months of lagering it is definitely a good idea to add fresh yeast when you bottle. I recommend 1/4 pkg of Safbrew T-58 dry yeast per 5 gallons, just sprinkle into the bottling bucket as you rack.

    I would recommend re-hydrating the dry yeast due to the fact that alcohol can break down the weakened cell walls of the dry yeast. You don't want that to happen.

    You need about 2.0 billion yeast cells to bottle a 5 gallon batch. 1 package of yeast contains about 230 billion cells. My suggestion of 1/4 pkg of dry yeast will be more than enough with or without re-hydrating.

    now just to clarify thats 1/4 pack yeast along with my normal priming sugar, correct? i just really dont want any bottle bombs, im using grolsch swing top bottles so they can take a little bit more pressure than a normal brown bottle but its still nerve racking.

    Correct, you will want to prime normally. If your primary was completely finished out and your bottling yeast is similarly attenuating to your primary yeast (both of which i am assuming are true) then adding more yeast won't do anything unless you add priming sugar. So just go ahead and prime like you would normally but also include a small amount of yeast.
