 Mashed in at 78.4C, stirred for 5 minutes because of lots of dough balls.  Fired for a few seconds, and hit target of 69C perfectly.\\
 Extracted 6.5L instead of 4.2L from mash.  Nice! Sparge until got 11L. \\

+Boil SG: 1.091 (expected: 1.083) \\
 OG: 1.072 (efficiency: 86%) \\
+Bubbling twice per second and 1cm krausen @ 6 hours.  Strong yeast. \\
-**Tasting Notes:** \\
+Since starter was 4.25L, it affects efficiency measurements. \\
+Actual brewed volume was 21.75L, plus 4.25L starter == 26L. \\
+Estimating starter was at 1.015 when pitched: \\
+( ( OG1 * V1 ) + ( OG2 * V2 ) ) / ( V1 + V2 ) = OG \\
+( (OG * (V1 + V2) ) - (OG2 * V2) )  / V1 = OG1 \\
+( (71 * 26) - (15 * 4.25) ) / 21.75 = 82 points (1.082 OG) \\
