Hi all,

I wanted to see if I could do a partial mash brew of an Oatmeal Stout. I found this recipe in the Joy of Home Brewing and was wondering if it looked like a good recipe, has anyone made it, or if there were any ideas to make it better etc.

I see there is gypsum in this recipe, is that necessary? My water is hard and the ph is around 6.9.

Also, I have a vial of Whitelabs WLP002 English Ale yeast and was wondering, can I use that in this reciipe?

I plan on trying it this Sunday so any posts would be helpful.

Recipe for 5 gallons:

1lb quick (cut and roled) oats
4 lbs 6-row pale malted barley
1/2 pound crystal malt
1/2 pound chocalate malt
1/4 pound roasted barley
3.3 lbs of John Bull dark malt extract
4 tsp gypsum
2 oz Willamett hops (boiling)
1/2 oz Crystal hop pellets (dry hopping)
Irish Moss powder (I have the dried, will that work?)
American or Irish ale-type yeast (see above, I have a vial of Enlish Ale yeast, will that work?)

O.G: 1.052 - 1.056
F.G. 1.012 - 1.016

Thanks,

Rob

I would change out the 6row for 2row and I wouldn't use the gypsum. I don't think you need the gypsum. I wouldn't mess with your water unless your sure it needs it. Other than that it looks good.

Has any non-macrobrewer even wanted to put 6-row in? My understanding is that it has a lot of diastatic power, so if you've got lots of adjuncts like rice and corn in your mash it gets things converting well - but at the cost of "grainy" flavors.

Hey, thanks. I'll make the adjustments. Can't wait to give the partial mash thang a try. Not sure what method I am going to use but the pail and a colunder sounds right up my alley.
