What kind of starter are you doing? The program is set for 'simple starter' that is merely a starter that sits on the counter. If you have a stir plate, make sure to select that option because for a 5 gallon batch it told me no more than 2L. How old is your yeast? That can play a huge role as well.

I would check to see if you have 'simple starter' or 'stir plate' selected first. I used to make this mistake and realized it the day after I purchased a 5L flask.

Hope this helps.

i dont have a stir plate and my yeast viabilit is on the 87%, but i do hake it every now and then.

There is an option for intermittent shaking. If you use the intermittent shaking option, with hybrid, 1.052, 87% viability and anything under 5.38 gal you will only need one vial/smack pack and a 2.5L starter. Use that pull down menu for the kind of starter you are using.

Are you making a lagered beer or just using a lager yeast?
Try out this calculator.
http://www.brewersfriend.com/yeast-pitch-rate-and-starter-calculator/

If you are making true lager of 1.052 OG and 5 gallons in the fermentor, intermittent shaking method for the starter, BF has a step one starter of 1 liter, and step 2 starter of 2 liters for an end cell count of 385 billion cells, for a target pitch rate of 365 billion cells.

To get a large number of cells with out a stir plate, it is often easier to do stepped starters, to keep the starter volumes lower, to be more manageable.

Do yourself a favor and build a stir plate. It's one of the cheapest DIY jobs in Homebrewing.

You need a computer fan ($6), a cigar box (free-$3), a steal washer about the size of a nickle ($.25), and a power supply--an old cell charger will work, but $12 otherwise, 6V is probably right--and a hard drive magnet, or good neodymium magnet ($9, with shipping, but you may find a local store and get one for $2). You glue the washer right on the center of the fan, then you can adjust the magnet so it's properly centered. Oh, get a well reveiwed 25mm or 1" stir bar from your LBHS or online: don't buy something that doesn't have homebrewers reviews becase many larger bars are not meant for high RPM and will throw. I canibalized most of my parts and spent less than $15 making mine.

Plus, it's fun to build things!

Using a stir plate is faster than without, but the yield is about the same. See my new calculator here:

thank you all for your anwsers, i real;y apreciate it.
i did a 2 l starter, and im going to do another 1.5 l, my next question is, when pouring the starter to my beer, if i only use the yeast that droped from suspenion, that white slurry on the bottom and discart the rest of the liquid, will i loose most of my yeast??

Refrigerate the starter until the spent wort layer is clear. All of the yeast will have dropped out of suspension.
