Yeah that's the recipe I have. You know I always figured when it says batch size 5 gal. that would be the volume in the keg. So if I got 5.5 in the fermenter than I would have 5 after transfer to keg. Also I didn't leave much of anything in the kettle it all went in the fermenter. I used all pellets and I bagged them.

Fact.

I figure on each oz. of whole hops holding 12 oz. of wort and increase my preboil volume to compensate. I've found that to be pretty accurate.

doesn't look like there a whole lot of difference in extracthttps://www.brewingw...ISB_RyeMalt.pdfhttps://www.brewingw...BrewersMalt.pdf

how do we know they are even correct?though I did the community brew with American Rye yesterday and all numbers came out as predicted

We don't but that goes for barley too. Sometimes changes in yield will make it appear as though the efficiency is higher or lower than it really was.

You should scale your recipe to the amount of wort you actually produce, not how much you end up with.

Very good figure of merit to know. Thanks.

You know, I never noticed how low the yield is for American rye. PM lists it as 30 ppppg but German rye is listed at 39 ppppg.

I don't know how accurate that is. If you look at Briess, for example (sice that's the rye malt I use), rye malt extract is listed at 80% while 2 row pale is listed at 80.5%. A negligible difference.

Yep, that brings it up to 37 ppppg.

it would be nice to get a data sheet with every sack

NCM says they'll do that for you but it never seems to happen when we do group buys.

So the amount in the kettle after boil is finished? Not in fermenter or keg?Denny, out of curiosity what is your typical OG and FG of this brew and your volume in the fermenter.

We get data sheets every pallet we order from MCM.Our club just closed out our 3rd full pallet of the year. So far we are on track for our annual totals.

Right. If you make your recipe for 5 gallons but produce 5.5, then it will be diluted.

I usually set mine for amount going into the fermentor accounting for kettle sludge

I always take a preboil brix and volume reading. I already know what these numbers should be according to PM. Then adjust the IBU's if necessary.

Then yours is probably more diluted than it should be too.

I shoot for 5.5 gal. (these days) at an OG of 1.073 ish and an FG of 1.015 ish. The recipe you used is the "old" 5 gal. recipe. I've scaled up the ingredients to get 5.5 gal.

so, pear with me for a bit, when your Promash Files you post say the batch size is 5 gallons, like our current Community brew, what you are putting in the fermentor is around 4.5?

[SchwanzBrewer]

I know how much wort I will need to get my final volume based on experience with my equipment. For most 10 gal batches I know I need between 12.5 and 13 gal preboil in order to have 10 gal in the fermentors. I set the recipe up in beersmith and have my equipment settings dialed in so the recipe volume is what I end up with in the fermentor and all the spoilage is taken into account. If you take the OG reading from the fermentor or from the boil kettle it will usually match the estimated OG in beersmith even though I generally have 11+ gallons including spoilage.

This is what I always wondered.Also to all, if your shooting for 5 or 10 gallons in the fermenter do you not account for the amount lost going into keg or just not worried about it?

Thanks good to know!
