6-row and rice - how much can I use?

[gmac]

I've been asked to make a full keg (15 gals or so) of crappy beer for an event.  The request was for a BMC style beer.  Not my sort of beer but it is what it is.
I made a first attempt using 80% pilsner malt and 20% rice with a single addition of Hallertau hops and it's still too flavourful for my testers.  So, I'm wondering if I should go to six row and more rice.  But, I don't really know how much rice I could use with six row. 
I'll likely be using Mexican Lager yeast.
Any help would be appreciated.  It's actually sort of interesting to see that making flavourless beer is harder than you'd think because its so unforgiving with nothing to hide behind.

I was just listening to a podcast that mentioned that Bud uses ~30% rice.  Maybe that and 6-row?

Considering a wit is ~50% unmalted wheat, I'd say your safe going up to 50% (conversion wise). Flavor-wise I have no idea.  Also, what IBU's are you at? Maybe just hold the hops near the kettle?

Why 6 row?

NA 2 row is 140 Lintner now. You could use 50% adjunct and the mash would be at 70 Lintner, so it would convert.

Yep.  There's a lot of old, outdated, currently incorrect info still floating around about the supposedly greater diastatic power of 6 row.

6-row does have more DP than 2-row, but both have so much it's not a practical consideration anymore, unless you're using a kilned base malt with low DP. Briess 6-row is 180 DP, while their 2-row is 140 DP. As long as the weighted average of the grist is over 50 you'll get conversion, though I'd target 70 to be safe. As Jeff pointed out, that's a 50/50 mix with NA 2-row.

You might think about using corn instead of rice. Rice is pretty neutral. Corn gives a sort of sweetness. I got a recipe from a former Coors brewer who consults for micros now. He said to use 17.5% flaked corn, 17.5% flaked rice, and Bo-pils for the balance. One hop addition, between 13-17 IBU.

But if you're set on making "crappy beer," just use sorghum syrup instead of malt, use bread yeast, and ferment at 95*F.

A friend uses up to 60% rice.

I'm confused. Why did they ask you to make homebrew if they want BMC style beer? Surely, by the time you've gone through all your testing, it would be cheaper to just get a keg of macro-pilsner, even if they're just reimbursing you for ingredients.

Why 6 row?

Cause I bought 10 lbs for a CAP and haven't used it yet.

Good reason!

It's for a fund raiser so we are trying to make as much cash as we can.  I'm donating the beer so I'm not making multiple batches to see if we get it right, it's gonna be a one shot brew (I made the 80/20 beer before this came up).
Plus, you may not be as familiar with Canadian beer prices.  We get screwed up here on the cost of a keg or any other beer for that matter.  A keg of Bud is $289.95 plus deposit.

That is a felony

Barf. Being a homebrewer actually makes financial sense in Canada? Crazy!

i made a cap last year that had 18% corn, 9 percent rice. i did use 6 row for about 18% cuz i had some. ibu around 29.  other than some astringency it was not too bad.
