    Hi Guys,

    I'm a big fan of Mr. Malty and how easy it is to calculate starter sizes for liquid yeast. However, tomorrow I am going to be using dry yeast, and It does not have a production date, only a best before. It is going to be a 30L batch and am eager to know whether or not I will need to pitch one or two packs. Is there a way around this on Mr. Malty, or alternatively another calculator that can work this out? Best before date on the windsor is 03/2014

    Thanks allot!

    Graeme

    Yes, go to the "Dry Yeast" tab that's on the calculator - it defaults to the liquid yeast tab

    Still looks for a 'calculate viability by production date' and even if that box is not ticked it seems to influence it.

    I would trust what it tells you with the "Calculate viability from Date" box unchecked. For a 30L batch two packs would be needed unless you're doing a beer with OG <1.040

    The OG of the beer is 1.050 and is a 30 litre batch

    Even you are going to brew a beer up to 1070 you just need 1 pack.Rehydrate it for 20-30 mins,nothing to worry about it.

    Thanks guys, I thought that might be the case. Though doesn't the safale dry yeast packs state 11g ferments 20-30 liters?

    I wouldn't risk underpitching
    Maybe but that would really be stretching it, I would rather spend the $4 (6 Euro?) for a healthy fermentation and peace of mind.

    I guess you are right. It's just that I have one pack of windsor and one pack of nottingham. I'm all for combining them and seeing where that goes, but if I could have got away with using one or the other I would have. I'll go with both to be safe. Thanks for your input!
