Promash Settings - 2006/05/26 22:21 Howdy All - Just wondering which hop utilization scale do you use in promash. The default seems to be Ragar but I think I remember reading that Tinseth is more accurate for late hoping schedules

Re:Promash Settings - 2006/10/05 14:54 Ray,

I was just wondering if you or any other Bloat has any thoughts on ProMash vs. BeerSmith brewing software?

Re:Promash Settings - 2006/10/05 16:31 Ray: I found this on ProMash's FAQ site:

Question: Why does ProMash produce different IBU estimates for my recipes than in printed books, magazines or other software programs?
Answer: The difference may be due to several factors:

1. The author of the recipe (or brewing software) may have used a different formulation type in the calculation. In ProMash, if you goto the System Settings, Hop Section, you will see there are four types of Hop Formulas to choose from (Rager, Tinseth, Garetz, Generic). You will notice that changing formulas from one to the other will change the IBU values is ProMash itself. So, in order to match IBU values in published articles or in other brewing software, you must be sure you are using the same equation type. Unfortunately most authors do not publish this, and many may in fact use their own proprietary formula. Many software programs (including ProMash) allow you to set the equation type to your preference.

ProMash ships with the default Hop Equation set to 'Rager'. Rager is the oldest formula to be published and as such, is published more frequently in printed recipes. This is not to say Rager is the most accurate, only that it is the default in ProMash. You can change the equation type in the System Settings, Hop Section to Rager, Tinseth, Garetzor Generic.

Brian: I've not used either but that's because I'm a Mac guy (both are PC). I do hear a lot of people really like BeerSmith though

for any Mac users out there BeerAlchemy is a good app.

Re:Promash Settings - 2006/10/07 21:39 Brian,

I evaluated both and prefer Promash. Seemed more intuitive to me. The only pain is that there you have to manually add some of the grains and hops not in there by default. It sure would be nice to be able to import database updates. Maybe we could set up a repository .... hmmmm

Brewing Software - 2006/10/18 01:53 Personally, I like using the old Martin Manning spreadsheet - you enter your OG, IBU, target color to start, then grain bill in percents and hopping schedule in terms of weight percent additions at various times.

You enter whatever efficiency values are good for your system...

I've always found that Rager's utilization numbers were too optimistic for everything. (Caveat - I brew big beers and certainly that's an issue as well - but I seem to produce underhopped pale ales with Rager)

The only downside of the spreadsheet is that it uses 100% as corresponding to perfect brewhouse efficiency that is around 33 points/pound extraction as opposed to some that use the number based on pure sucrose or lab values, both of which aren't really reasonable goals for home brewing systems.

I might even have a copy in metric if Boyce is interested...

I've never used any of the commercial packages out there - I guess I'm too cheap to pay for something when I'm already happy with what I use... Arthur: What's so bad about being drunk?
