I use a spreadsheet that automatically adjusts ratios based on system eff, desired og and color. The ratios change a bit depending in the recipe. I use enough grain so that the first running wort will be 10 gallons. Different grains have different absorption levels so I do sparge a but sometimes...
The list is on our website in the brewing store link www.flatrockbrewery.com. We are bagging grain and hops now but everything will be available for sale by Wednesday. If your familiar with nw Ohio it's pretty easy to get to the store.
I parti-gyle every brew but I usually brew a 10 gallon first running then run another 10 gallons thru the grain while the first is boiling. I normally hit around 50% eff with the first and 25-30 on the second. Using beersmith really helps because it makes is easier calculating OG in both batches...
I was actually thinking about a parti-gyle brew with the first running going to barrels then bottles and the second run going directly to kegs. We live in a rural area and most of the beer drinkers are coors lite drinkers. So the lower gravity second run might be a good fit.
Our brewery staff are debating selling bottles vs kegs. Kegs seem easier to deal with but we barrel age much of our beers and bottle conditioning seem to go hand in hand with oak aging.
It's a huge debate in our brewery if we should sell bombers over kegging our beers. Most of our beers are oak barrel aged and to me that just screams out for bottle conditioning.
