    Let's get this thing rolling. First question:

    What style is a traditional Eisbock made from? Doing some reading today and I'm not finding my answer. What would the German's make it out of?

    Based on the above reading I am thinking a dopplebock.

    That's pretty much what my perception is...... brew up a Dopplebock ... decoction mash and all..... then allow to begin to freeze .... remove the ice crystals ...
    Every thing I have read on the subject recommends a long lagering after the freezing part to smooth it out .. and balance the malt/alcohol. I would be tempted to skip the lagering period before freezing to save time.

    To me the hard part is judging when to stop freezing ..... go to far and you will loose malt character .... not enough and you don't do anything ...

    Based on some reasing it sounds like the time to remive the ice is when it start to get slushy. But do youremove the ice or rack the beer off of the ice?

    My understanding is to scoop out the ice crystals with a sanitized spoon ...

    II think the bigger and maltyer beer the better ... well to a point ... maybe something between 7.5 and 9% APV ...
    an alt might not leave enough .... uh.... guts to stand up to the increased alcohol

    Now if you wanted to just make ice distilled whiskey ..... and freeze it hard a couple of times .... the alt may be a good place to start ..

    how does the mash schedule look? Seems pretty standard.

    I would be tempted to skip the 147 degree rest ... and extend the 156 to an hour .... but what you have may be more traditional ... that's pretty similar to what you used on the o-fest? How did it turn out? If you liked it .... go for it

    I agree with the above, when I have made an eisbock I used a simple martzen base but amped up a bit to up the ABV, then I poured it in sanitized plastic water bottles, the PET ones that babies r us nursery water comes in, I drilled a load of holes in a second lid, screwed it on and turned it upside down on a pitcher, within minutes the alcohol began dripping out into the pitcher, there was a notable break when the alcohol was mostly out and all that was left was ice. I kept it chilled and carbed low in a soda bottle with a carb cap, served it as a cordial in a snifter after a dinner of sauerbraten, spaetzel, and red cabbage. That was a meal worthy of being served as your last!

    I don't normally keep Pilsen malt on hand, so I might be tempted to up the Munich by a pound, aside from that it looks pretty yummy, the chocolate wheat has a nice velvety mouthfeel that might get lost when freezing. But will help maintain a beery feel after concentrated. One thing, hop bitterness goes up with freeze concentrating, your recipe seems right on target in that respect

    Thanks for the feedback. Now I just have to find time to brew.

    if i were going to do it (on purpose, this time), I'd do the freezing in the keg, then transfer to another using co2. the tricky part would be guessing when it's frozen enough.

    as for the letting it lager after you eis it, it may not take all that long to get it tasty. i accidentally eised a pale ale, about 1/2 way through the keg. i couldn't figure out why the beer suddenly turned delicious and a good bit stronger until i went to clean it out and had a big ring of slush in there. there wasn't the slightest bit of harshness to smooth out.

    and the alt sounds delicious eised. after the pale, i'd say that a bunch of beer styles would turn out as good eis-whatevers.

    Can you all take another look at the grain bill and the mash steps. I'm not over familiar with style so I want to make sure I have a good beer with the recipe.

    the grain bill looks delicious, but from my limited experience with decoction mashes, i'd shorten the protein rest to 15-20 minutes. with modern malts that rest really doesn't make a big impact. if you were using cheap undermodified malts it would help but 15 min should be all you need. then i'd raise it up to 147 for 15-20 and bump it up to the 156 for about 30 minutes.

    and maybe up the pils a little, now that i think about it. doppelbocks are already very rich/malty and you're going to be concentrating those flavors. it would be a shame to go over the top and end up with a sweet beer.

    how much would you up the pils by?

    i think around 10-15% would be nice. you could probably go as high as 25%, but that would change the flavor profile a good bit.
