Default Why 6 row for pumpkin ales?

It seems like I use 2 row for almost every beer I make, except pumpkin beer. I live the stuff, but 6 row is way more expensive at my local brew store than 2 two.

Does anyone have a good pumpkin ale recipe using 2 row or an argument as to why I can get away without using it?

6 row has more hull material for better filtering and a little more diastatic power for more conversion.
pumpkin likes to clog and absorbs a lot of enzymes.

use two row if you want, sub it for the 6-row recipe, just throw in an extra pound of 2-row and a handfull of rice hulls.

This is very interesting. I had no idea that pumpkin would absorb enzymes. Do you know any of the science behind why this happens, or is it just that by adding more material to the mash it simply acts as a sponge?

Who says you need to use 6-row for a pumpkin beer? Use whatever malt you want, it doesn't matter. You should be using 0.5 to 1.0 lb of rice hulls anyway, so the extra hull is moot. And Pumpkin has very little starch, so you don't need the extra diastatic power of 6-row, plus it's not a high percentage of the grist anyway.

6row has more enzymes than 2row and is typically used when brewing a beer with adjuncts. That is why 6row is suggested when using a pumpkin in the mash.

6-row doesnt have that much more diastatic power than 2-row that you couldnt sub it directly. some rice hulls may or may not be necessary, but you shouldnt need any extra grain

its the starch in the pumpkin, it uses up enzymes like the grains do

I thought amylase was a constantly moving enzyme. Wouldn't a longer mash schedule be sufficient to convert the extra starches?

That logic makes no sense. "Adjuncts" are starchy cereals that need the extra diastatic power for conversion. But pumpkin contains very little starch, something like 1%-2% IIRC. So there's no need for extra enzymes since it's not a starchy adjunct.

Again, there's nearly no starch in the pumkpin to "use up enzymes."

Anyone pondering the starch content of pumpkin should do a google search or just pick up a can of pumpkin puree. It's not brain surgery.

By definition, an enzyme is just a reaction catalyst which doesn't get modified during the reaction it's catalyzing. Having more enzymes in the mash is helpful if you have more starch just to speed up the conversion, but nothing is 'using up' the enzymes and everything will still convert if you wait long enough.

I'd agree that 6-row isn't necessary. Pumpkin is mainly sugar and fiber with a little bit of starch. 2-row should have plenty of enzymes to convert what starch is there in a reasonable time.
