I am looking to make the move to all grain soon, possibly my next brew day, using Denny’s batch sparge method. My question pertains to style. Is there a style that tends to be more lenient when starting something new? I tend to brew without an assistant, and with something new going on, I know I will be slowly getting through the process and I read and re-read my notes, and recipe. Whatever I brew, it will likely be from an existing recipe, as I have not done any recipe formulations on my own yet. I am looking for a forgiving brew, as I have little time for experimentation, only getting to brew every 4-6 weeks roughly. I guess I’m not expecting perfection, but would like to keep it simple and easy to follow. I have not brewed any lagers yet, but was considering John Palmer’s California Common. My equipment limitations are as follows, really just a a boil kettle that wont handle a huge batch: 7.5 gallons. I know i could start with a smaller batch such as 3-4 gallons, but again, need max volume of beer to get to next brew day. Any opinions and info would be greatly appreciated. I hope all can follow my ramblings here and help me out. 
California common is a good choice if you can keep the fermentation temp in check.
simple grain bill, just 2 row and a little c60 or similar and you can get away with single hopping northern brewer or add some cascade it for complexity.
It was my first all grain.
The most important thing to remember when making the switch to AG is…
RDWHAHB (or commercial beer if no homebrew is available)
What Morticai said.
A stout or porter are good beers, as the strong flavor will help hide imperfections.
I agree with Mort but will also throw in a pale ale, mostly base malt, a little crystal, a good bitter charge at 60 minutes and some later addition hops. You can always then add dry hops to mask anything that might seem off:)
My first was a pale ale… My second was a cherry stout. If you like IPAs, I don’t see an issue with starting with one of them. I was told to brew a pale ale before brewing an IPA. The way I see it, if you are capable of lifting a few more ounces of hops at a few different times, you can brew an IPA 
I’d go with a pale ale.
2-row, c-20 or c-40, mash at 152°, cascade hopped, and us-05. Keep it simple and have fun.
A simple pale ale is a pretty good place to start. 2 row, crystal, and some Cascade. And if temp control is an issue (and usually is at first) then 1056 is neutral enough to be fairly forgiving, at least compared to more estery strains.
Jinx. ;D
Think I was finishing typing when you posted ! Oh well, I think a lot of us started with a pale ale 
Thanks all so far and keep them coming. Have made an IPA, DIPA, Barleywine, Smoked Porter and Evil Twin with extract plus grain. The DIPA was by far the best(LHBS Pliny clone) loved by all. Think it will be another IPA, really like what the late additions bring.
Edit, I am also sitting on 3 oz Amarillo, guess its an easy choice!
What are the other hops you have available?
Those are the only I have on hand, but have to shop for the malt, so can pick up whatever the LHBS has available. Probably going for some cascade: have not used any so far. Have 3 LHBS easily accessible to me as I drive around town for work, I can usually find what i need.
Edit: I have cold temps down cold… Picking up a ferm wrap by next brew day as basement is in low 50’s here in Indiana right now( of course, as soon as I buy the freezer and temp controller ::))
You can get by with a small brew kettle. Even if you have a decent amount of boil-off, you can run some of the wort off into a side vessel and boil it on the stove, then add it to the rest near flameout when there isn’t a danger of a boil-over.
I agree with the pale ale/IPA, lots of hops, and a forgiving american ale strain will easily cover up any issues you have with the all-grain portion. Also agree with the RDWHAHB advice, it isn’t rocket science.
Don’t be disappointed too quick. My first AG was about as good as my previous extract brews. But I started addressing my little problems one at a time, learning as I went, with great improvement along the way. I’m still working on it an expect I will be working on it forever. That’s the fun. Searching for the perfect pint.
This is certainly true. My beer has always been pretty decent, not exceptional through the move from extract to all grain. The biggest difference I have noticed is that I can make beer all-gran that would be impossible to make from extract.
My analogy, it’s fishing with bait vs hand tied flies. But like all analogies it only goes so far.
Thanks to all, finally got the time and freedom to do my first all grain batch. I went with a smoked porter recipe from my LHBS. When I made it from their extract with grains kit, my girlfriend loved it. This made it easier to brew today, knowing she wanted more of that brew. As a first attempt at all grain, I think it went very well. I would think twice about brewing when its this cold again though, heating strike water and getting wort to a boil was rough when it was only high 20’s outside today. I mashed in in the kitchen, and it went well. Many thanks to the folks at brewersfriend.com for their spread sheets, calculators, and checklist. All kept me on track and I did not leave anything out. With cold grains(forgot to take out of freezer!), their strike water calc said to heat to 168 for my 150 mash. It settled at 151 and only dropped to 148 by the end of the hour(cant believe that old cooler held temp that well!) As I mention that, also many thnaks go out to Denny and his batch sparge info. I think my tun was a bit of a task, but it worked like a charm. The only real issue I had was my BK, had to collect only 6 gallons to boil. I mashed with 5 gal and sparged with 5. May not have been the best efficiency, but my pre boil OG was 1.06 and brewersfriend calc estimated 1.068. After the boil, my gravity was 1.072, their calc estimated 1.074: I am very happy with those results. Now I just need to get a bigger BK! If anyone s interested, I can post the recipe, if its cool to post someone else’s recipe: trade mark/secret? When I did the extract version, it finished overly sweet, with only pack of Muntons Gold ale yeast. Brewersfriend.com calc said this batch needed at least 2.5 packs of same dry yeast but I went with 2 because I bought before going through their calc. Hope this batch comes out a little drier. Again thanks to all who made suggestions and helpful hints. Now I have to just sit back and wait for this batch to do its thing!
Congrats ! It only gets better (and more obsessive) from here. Enjoy !
Let us know how it turns out!
glad to hear it went smoothly. I think you’ll see a drier finish with this than with the extract kit. Did the extract kit include some dark extract? that is notorious for leaving a lot of sweetness behind.
EDITED TO CORRECT MY BAD TYPING
