I was brewing Ed Worts robust porter recipe but realized I did not have the 8oz of malto dextrin. I was contemplating using lactose instead. Any idea how this will affect my beer and also how much should I used?
 
malto dextrin will assist head retention more than the lactose will, but the end result, ie to sweeten should be more or less the same?

Just my thoughts on it.
 
maltodextrin adds body to a beer without adding any actual sweetness or flavor.

lactose will add a slight sweetness.
 
Would you add the same ammount in your opinion to a porter? I was going to add 12oz of dextrin to 7.5 gallons?

If you're asking me... I never add sugars to my beers so I can't really give an answer.

If I want more body, I just mash at a higher temp.

If I want more sweetness, I just add more crystal malts.
 
Lactose is about twice as sweet to the average person as MD. But, MD can vary by a factor of 5 depending on the final composition.

I'd go with half as much lactose, but if this is a mash or PM, raising the mash temperature 2F is probably a better choice.
