    Hey guys, this is a strange scenario. I haven't brewed extract in a few years, and I find myself dumbfounded by it now. I'm taking an all grain Oyster Stout recipe and converting it to a 15 gallon batch of extract brew for a demonstration. Does this sound right??

    20lb Maris Otter LME
    10lb Light LME

    Steep -->
    1.5lb Crystal 80L
    1.5lb Caramunich
    1.5lb Roasted Barley
    1.5lb Pale Chocolate
    1lb Black Malt

    5oz (or 37AAU) Challenger 60min
    21 oysters

    15 gallon batch

    Right? That depends. What was the all grain recipe and what was your normal mash efficiency?

    Well, we wanted to tweak the all grain recipe after the first trial, which we're doing here slightly. I can't remember what our efficiency was, but the OG ended up being something like 72.

    The point is...nobody can tell you if you converted it 'correctly' (or reasonably) without seeing the original recipe.

    Right, I'm not so concerned about whether it was converted correctly, rather if this sounds like 15 gallons of extract stout or not.

    I'm no expert, but 2 lbs of malt extract per gallon should net 1.072 OG, if not higher, and your steeping grains look like a proportional amount to get the right color, at least.

    Like bgjohnston said, you'll get 1.072 OG just from the extract. The grains will also contribute some fermentable and nonfermentable OG. Do you use brewing software? Steeping extraction efficiency is generally less than mash efficiency...let's say you can expect to extract an average of 20PPG from each pound of steeping grains...

    (7 lbs X 20 Points per Pound Per Gallon) / 15 Gallons = ~ 9 Points

    So maybe an OG of 1.072 + .009 = 1.081

    You might get some better responses to the actual recipe composition by posting as a 'critique my recipe' thread rather than 'going from all grain to extract.'

    It looks like a big dark stouty beer to me. Some might think it should have more of the roasted malts in it, but I think I personally would like the grist.

    I'm against the oyster part. I've never had an oyster stout, but at best, it seems gimmicky to me. At worst, it seems like a possible waste of expensive extract. My 2 cents.

    That is a reasonable suspicion, but it really is a different breed of stout, and in fact, it may be my favorite kind of stout. If you get a chance, try Flying Dog's Pearl Necklace. It is phenomenal. I think most people are pleasantly surprised at the effect of adding salt to their favorite sweet flavors (fruit, caramel, etc...) and stouts are no exception.

    A purist! Fantastic! I'll have to keep you close for advice on brewing finnickier traditional styles.

    Remember if you are doing full volume boils to take the volume of the extract into account. I converted one of my recipies to show some guys how to brew extract. Then had to boil a little longer before adding my hops to bring the volume down. Not a big deal just doesn't make you look as smart!

    I have been going back and forth between all grain and extract the last couple of years.

    I use the same techniques to make my recipes for extract than I do for all grain. Start out with a light base malt (dme) for most of the fermentables and use specialty malts for flavor/color/mouthfeel. I tend to bump up the specialty malts by like 20% assuming color and sugar extraction is going to be less when I steep in a bag vs. mash. I also do full boils.

    30lbs. of dme is going to take quite a bite out of your wallet.

    This was a group brew shared by my homebrew club (we split the cost of all the supplies). Ended up making only 10 gallons, and I did, in fact, forget the account for the volume of the extract. :grinning:

    It's got the typical Flying Dog immaturity in the branding, but I'll vouch for it. It's a good beer.

    Yeah... I sort of cringe every time I order a Flying Dog and read the name.

    I don't have a beef with Flying Dog's beer, but the name sort of takes my thoughts away from the beer.

    Without commenting on the specifics of the thread, I would just like to say that extract brewing is GOOD. I really didn't have a lot of hope to make an especially good beer when I tried my experimental two-ish gallon batch of extract brew about five weeks ago. Not that I'm not still doing all grain, but I wanted to play around a little. But the beer has come into its own, and it's damn fine beer. Gave a bomber to a friend and he managed to not only drink half of it for himself, but impressed a female with tasty beer all at the same time.

    Glad I could help on that. :grinning:

    So don't fear the extract, even if it's amber or dark. Extract beers can be excellent beers. Fundamental brew process is about 95% of the challenge. The rest is figuring out how to most impress your friends with the finished product. :sunglasses:
