Just did my first 2 3g batches today. I usually do 5g. Is it normal to get better efficiency with 3g. I did everything the same. Same grind, same mash thickness, same mash tun, same sparge but my efficiency was 7% higher. With 5g batches I usually hit 73% but I hit 80% with both these. Only thing different was I did a 60min mash rather then a 90 min. I wouldn't expect this to effect efficiency positively though?
Better efficiency 3g vs 5g

For the same water to grain ratios (both strike and total) the efficiencies should be the same, all else being equal. So, something must not have been equal. Without the appropriate measurements, it is not possible to know if the increase was due to better conversion efficiency, better lauter efficiency, or just measurement error.

Less thermal mass, more temperature drop?
Good point, proportionally greater pre boil volume with the smaller batches would help efficiency. Something I hadn't thought of but sound reasoning.
This makes sense. I did have a thinner sparge grain to water ratio with these brews. My conversion on the stout was 96% but I think this may have been a measurement error. Seemed very high. The blonde ale was 70%. I could be measuring this wrong though. In Brewers friend do I enter my SG before or after I sparge when it says SG at mash completion. I assumed the SG at mash completion was before I sparge and then pre boil SG was after the sparge?
