Beer smith reciepe scaling

[brewman42]

Hello,

Just purchased the beer smith 2 app. Was using the brewers friend free version.
My plan is to brew a German hefe this weekend but I'm trying to scale my recipe from 5gal to 3 gal. I've plugged in all my numbers and it seems to have effectively adjusted my grain bill. I'm just wondering if anyone has had any experience going from a 5gal to 3gal recipe with any success? If I can trust it?

Here's the grain bill it has given me.

4lb wheat malt
1lb pilsner malt
8.2oz flaked oats
4.1 flaked wheat
12.8 rice hulls
8 oz Vienna malt

Also, I'm using the wyeast smack pack 3068 should I still use the whole pack? Will it throw off my fermentation/attenuation?

Thanks a lot!

i do this all the time. its fine Use the whole pack you will be fine. I brew 3 gallons all most of the time and scale down from 5.

When scaling for size in BS, one time I noticed where it really changed the percentages of the recipe. I don't know if the software knew something I didn't, but when I posted it in the recipe thread, I was told I should keep the percentages the same, so that's what I did in BS. Now when I scale, I usually check to make sure the percentages are pretty close from the original recipe.

^Ditto

What I do when copying recipes is to just calculate what their original % of each grain is, then when you add all the grains in the app, just hit the %grain button (or something similar to the right of the ingredients list) and manually type in each grain's % you want. When you adjust your batch size the amount of grain will automatically adjust, and you can easily verify this.

When using BeerSmith's Scale Recipe function, you should be aware of the options available to you because they make the task a lot easier. The scale function aligns the recipe with the equipment profile you give it. So, it isn't always linear because you may have different efficiency, trub loss or boil off rates and that will sometimes change the ingredients a little.

When scaling beers with a lot of specialty malts, BeerSmith may calculate less of some because they contribute just about as much color without more weight. In return, to match the OG, it'll usually add more pale malt. The result may be different percentages, but the same OG, gravity and IBUs.

However, if you need a straight linear scaling, simply uncheck the "match original gravity, color and bitterness" box at the bottom of the popup window. Your percentages will stay stable, but color and OG may change, slightly.

Thanks for the info. I didn't realize all that.
