A member of my local brew club is relocating to Austin, TX from northern Indiana in a few weeks. He has been unloading quite a few brewing items that he would rather not pack and move to Texas. One of the things he was sellings was a complete robust porter "kit" he had put together based on this recipe:

All-Grain - Bee Cave Brewery Robust PorterThis will make 5.5 gallons of Porter. Preboil is 7 gallons.11# 2 Row1# Chocolate Malt1# Crystal 404 oz. Black Patent1 oz. Roasted Barley8 oz. Flaked BarleyMash at 150 degrees for 60 minutesAdd 8 oz. of Malto Dextrin to boil at 20 minutesHops:1 oz. Northern Brewer at 60 min.0.5 oz Cascade at 60 min.Hydrate a package of Nottingham.Ferment for 2 weeks, then rack to keg or secondary.

-recipe by "EdWort" from homebrewtalk.com-For $20 all ingredients were included (except he sub'd S-04 for the Notty & he threw in half a bottle of Star-San). And, from reading the recipe discussion here: EdWort's Robust Porter, the malto dextrin was included to increase body and mouth feel. Here's my question: Couldn't I just raise the mash temp, to say 154*F, and skip the malto dextrin, or am I missing something? I've never used malto and am not necessarily opposed to it, but the way I understand it, isn't it as simple as increasing mash temperature to get the unfermentable sugars that would add the body that goes with a robust porter? I've made a couple of porters (154* mash) and (except for missing WAY low on mash temp on the first one) the body that I was after was there.Help, maybe I just don't understand the contribution that the malto dextrin will add.

If you alter your mash conditions, you are going to alter all the sugar production from starch of all of your malt.By using Dextrin malt you can balance the profile and obtain more fermentable extract from your mash, saving you money (if you are a giant brewery).Mostly it is a flavor balance thing (and mouthfeel thing).MolBasser

Hey JimI brewed this yesterday. I got home just in time today to avoid my 1st exploding fermenter from a clogged airlock. I didn't expect this one to take off like it did and I didn't have a blowoff on it.One of our new MEGA members came over, brought brats, and hung out to get an understanding of the precess. Eli lives in the Dunlap area, very bright, and is a pretty cool guy. A good addition to the club. He brought a nice sampler with him that included some Bell's Batch 9000 and some Michigan IPA's; good stuff. Posted Image Ken
