BeerSmith to Recipe difference

[403Brewer]

I'll preface this to saying I'm new to brewing, about 5 batches done and all turned out well, but never used the beersmith software to program a brew before. Anyways I've entered a recipe from the BYO 250 Classic Clones magazine and the ABV calculated is super low (2.3%). This is a Guinness Extract recipe that I'm doing. Can anyone suggest what could be the issue? The amount of extract in the recipe seems really low, 3.2 lbs total DME/LME for a 5 gallon batch. Thanks for any advice.

Yeah, 3.2 lbs DME in a 5 gallon batch is really low and will give you a starting gravity of less than 1.03. Depending on the finishing gravity, the ABV calc seems generally close, but the recipe seems wrong.

Guinness is a lighter gravity beer, but not that light.

Could it be a partial mash recipe? Maybe they intend on some gravity from mashed grains.

 

[bennie1986]

What kind of Dme do you have to use anyway?

 

[403Brewer]

Ya it's a partial mash, about 1 lb of mash grain, 1 lb of barley , still comes out with a starting OG of 1.028. The recommended dme is light malt extract. Does beer smith take any gravity from a partial mash?

^ This would be my first question, too. What is the actual recipe? That will help a lot.

Partial Mash
1 lbs 6.1 oz Pale Malt (2 Row) UK (3.0 SRM)
1 lbs Roasted Barley (300.0 SRM)
9.9 oz Barley, Flaked (1.7 SRM)
Boil
14.1 oz Light Dry Extract (8.0 SRM)
2.40 oz Goldings, East Kent [5.00 %] - Boil 60.0 min
2 lbs 9.6 oz Light Liquid Malt [Boil for 15 min](3.0 SRM)

1.0 pkg Irish Ale (Wyeast Labs #1084) [124.21 ml]

Maybe partial mash isn't the best term for this, Extract with grain is probably more accurate

 

[chickypad]

It includes base malt so it's a partial mash. Make sure you have partial mash selected in Beersmith not extract or it will not take into account most of those gravity pts.

 

[boydster]

That's a partial mash, but I come up with 1.033 OG for 5 gallons which is still pretty low. I think Guiness is a few points higher than that - enough to get it up to ~4% abv, anyway... Maybe some additional extract would be the answer? Maybe 2.5lbs DME and 1 lb LME - that gets the OG up to 1.040 for 5 gallons...

I'm getting 1.042 at 75% efficiency.

My brew app gives 1.038OG at 3.7%ABV for this recipe.

Yeah, I just noticed and was clicking back to this thread when I saw your reply, I undershot the DME by a full pound when I entered it I come up with 1.042 at 5 gallons, or 1.039 at 5.5 gallons (you'd probably brew 5.5 gallons and hope to bottle 5 gallons)

Wow ya I'm an idiot...had it set on extract. Thanks for helping out a rook with a rook question guys
