When you have a chance check out Weyermann Malt website and take a look at their recipes. Purchase their malt when using a recipe from them.
I use Weyermann dark and light Pils floor malt and sauer malz for Oktoberfest. Their floor malt is slightly under modified and low in protein.
It's better to stick with fresh yeast out of a package for consistency instead of harvesting yeast because yeast have a habit of becoming senile and it isn't worth adding a weak link.
Before adding hops bring the wort to boiling and skim off hot break until it stops rising or drastically reduces then add bittering hops and skim off second break. Boil the hops for an hour. Less hops are needed because the wort is cleaner, and less goop is transferred into the primary fermenter.
Secondary fermentation is required when a Beta (conversion) rest is used. 140 to 145F. The rest is omitted in recipes because fully modified malt lacks Beta amylase.
Only one type of yeast is needed during primary and secondary fermentation, except for maybe in high octane beer and Belgian beer. Yeast fuel is glucose and yeast rips through all of the glucose during primary fermentation. After glucose is burned up yeast turns its attention to complex sugar, maltose and maltotriose. Maltose and maltotriose form during conversion.
During secondary fermentation yeast absorbs maltose through the cell wall and an enzyme within yeast converts maltose back into glucose. Glucose is expelled back through the cell wall and yeast use it for fuel. During secondary fermentation the beer comes closer to expected FG. After two weeks the beer is transferred to kegs and during the aging/lagering cycle yeast does the same thing with maltotriose and natural carbonation occurs. The beer hits expected FG. Priming sugar and CO2 injection aren't needed.
When a recipe recommends using fully modified malt, single temperature infusion, only primary fermentation and adding priming sugar or CO2 the beer produced is similar in quality to Prohibition style beer.
