Comparing two IPA recipes, pitch rates...

[GoldDiggingBrewer]

Hey guys.

I'm starting a new Summer project -- I'm brewing a collection of one-hop IPA's using a different hop for each brew.

The grain bills and yeast and brew method are the same for each brew, but I came upon variations in my pitch rates for two current IPAs; Columbus (15) and Magnum (15).

The OG, IBU, SRM, ABV are identical in both recipes. Both late Hop additions

But according to BrewersFriend;

The Magnum IPA requires 98b pitch cells.

The Columbus IPA requires 209b pitch cells.

Anyone know why this is?

One of the settings must be off - check the batch volume and the target pitch rate (i.e. set for ale, lager, etc). 98 sounds low for a 5 gal batch, that's likely the one that's off.

Edit: let me guess - your OG is 1.060 and you have the Columbus IPA set for the pro brewer recommended .75 million/ml of wort pitching rate while the Magnum is set for the manufacturer's .35 million/ml on the drop down list. That gives the numbers you listed.

Figure it out... It was the pitch rate setting.

You have the pitch rate set for the magnum IPA at .35 million/ml. The more standard rate used in most calcultators is .75 million/ml for ales, which on the brewersfriend calculator is called "Pro Brewer 0.75 (Ale)". You need to change that setting.
