Two minor updates, The mandarina IPA is INCREDIBLE. In the past week it's flavour has changed dramatically. Gone has the slight floral note and WHAM! it now smacks you in the face with citrus/mandarin orange. Awesome Second update is my bayou IPA once cooled had an OG of 1.058 So I had to water it down a little bit and now have 20l bubbling away on the trub from my bitter. I must have made a mistake with my weighing out, otherwise I hit 90% efficiency. I think not!
