I did my first PM today, it didnt go as well as expected. I should of waited for the mini lauter Tun I purchsed, but as usual I didnt. I still think the beer is going to be good, but I had a target SG of 1.064 and ended up with 1.050 so I know it wasnt good. I wont use this method again. I just want to know how to figure efficiency

It depends what efficiency figure was used to estimate the 1064 figure.

I find most recipes use around 75% to estimate potential OG..

(64 / 75) * 100 = 85.3 OG for 100% efficiency.

(50 / 85.3) * 100 = 58.6% efficiency.

It's a little more complicated for PM, because you have to discount the extract. Or take a gravity before adding the extract.

Let's say your recipe had 3 pounds of grain (half 2-row, half specialty) and 6 pounds of LME. TG 1.055 @ 5.5 gal.

The LME gives you 40 points. So you're expecting 15 points from the grain. That's about 75%. So, if your OG is 1.050, you actually got 10 points from the grain and an efficiency of (10/15)*75 = 50%

So LME is worth 6.6 pts per lb then?
What would DME be worth?

Im sort of understanding it now. Thanks you.

What exactly was the recipe because it is hard to know how well you did without the information. DME is about 20% more concentrated than LME. You get between roughly 37 gravity pts. per gallon\per pound with LME.

How do you figure out the gravity from the ingredents? Is there a chart or do you type it into beersmith?And your good to go.

Yes, when you formulate a recipe it should list the OG based on ingredients,effieciency and batch size.
By the way, what's Purple Porter?

It is a recipe that I put together from other porter recipes. The runoff came out so dark it looked purple. Then on top of that I collected 10 gal of wort and it took 3 1/2 hours to boil down to 6 gal. I didn't mean to collect that much so hopefully it comes out O.K.

9lb 2 row pale
1lb caramel
1/2lb cara pils
1/2lb munich
1/2lb 30L crystal
Wyeast 1028
1oz tett (60min)
2oz fuggles (30min)(1oz15min)
1oz cascade(cool down about 10min)
1 1/2 lb honey

Use promash to project OG based on your system.

Extract amounts have no effect on efficiency because extracts are already converted to sugar (no starch).
