Ok, so I'm brewing an Oktoberfest this weekend and I put the recipe into beersmith. I'm basically COPYING it out of Brewing Classic Styles. I don't want to futz with coming up with anything new, just want to ferment a nice Oktoberfest, and Jamil and Co. usually know what their doing.

Anyway, I enter the numbers and my OG comes out to 1.070+. The recipe says 1.055. WTH?? I mess with some settings and I get numbers all the way from 1.070 + to 1.066.

So I mash with a bit more water, and give it plenty of sparge. I get 1.40 into the boil and boil for 90 minutes, as I am using Pilsner malt for a bit of the fermentables. I end up with 6.5 gallons of 1.058 wort...

I thought about adding some water to top off, but I didn't have any boiled and sanitized water on hand. I guess it will be ok. Except I forgot the Irish Moss again!!

I had a 1.6L starter ready and in the fridge to acclimatize. Pitched it the next morning cause the wort was still not down to 50. We'll see what happens.

I had about 1.5 gallons of wort extra so I put it in a 3 gallon carboy and added some Notty.

Anyway, how could the numbers be so far off? I've never had beersmith be off more than what a bit of tweaking to match my process would account for!

Brewing Classic Styles has all 6 gallon recipes. If you're making 5 gallons, just scale it down. I think it's 70% efficiency or so, also. That could be a factor.

Yooper probably nailed it. Also, in Beersmith, did you check boil-off rate?... Loss To Trub?... Potential Yield of the Pilsner/Munich malts?

Don't worry about the Irish Moss. I never add kettle finings to my lagers and they always come out plenty clear. The lagering process takes care of that. It also helps to have a good hot and cold break during/after the boil.

It will be better, stronger beer IMHO.

Don't sweat it.

Oh, sht.. I think you are right. I entered it as 5. I did change to 6, but probably had not made all the right adjustments at the same time. Good info to know!

Yeah, it was only a bit stronger than the recipe. Problem is I wanted a lighter beer this time. But it's not THAT strong anyway.

I did not adjust boiloff rate because it had been good where it was before and although it's winter, I thought it would be easier to just plan on a bit more water and keep an eye on it.

I was thinking about adding more water, but I didn't know how much room I needed for headspace. This was going to ferment in the garage and I didn't want a huge mess in the freezer since I can't keep an eye on it. I don't "think" that lagers blow off as much, but then I thought it might be neat to put the extra in a different fermenter and do it up as an Ale.

I pitched yeast about mid-day, and by evening I still saw no signs of bubbles. Not exactly what I had expected, considering the size of the starter, but I am a Revving this one. I bet by the time I get home tonight it's going like crazy.

The Notty got pitched early evening and by bedtime was already starting to chug along!

Wait, what? Your first lager, and you pitched Notty? Still not your first lager then.

I made a partial mash verision Jamil's Oktoberfest from 'Classic Styles' yesterday as well.

One small change I made was using 14 oz. of sparkling amber DME to cover 1 lb of the Munich LME called for in receipe.

Anyway, I proceeded without realizing it was a 6 gallon recipe so only diluted it out to 5 gallons. My OG ended up being 1.060 rather than the expected 1.055, now I know why.

I pitched my Bavarian Lager yeast at 50 deg. last night. This morning there was only a small bit of action on airlock. Hopefully when I get home tonight it will be rocking.

No, I pitched a White Labs Oktoberfest in the 5 gallons in the garage.

The Notty went into 1.5 gallons in the back bathroom.

This way I can compare the two yeasts.

Next up is a Bo-Pils for my buddies. I tasted one at Herford and Hops last summer and really liked it. So much more flavor than I expected for a beer that light. But I didn't have any of that yeast, so the Oktoberfest got the call-up.

I actually have a pouch of Wyeast American Lager in the fridge and want to build up a starter and brew that next, but I haven't found a recipe yet. Any suggestions? I want to use Corn, I know that much.

Also as a bonus, my mom gave me an old Mirro Pressure Cooker so I can wash my yeast and sterilize the stuff it goes into. I want to try freezing some washed yeast.

She couldn't find the pressure weight though, so now I'm hunting for a deal on Ebay...
