What was I thinking? Posting about Mackeson but forgetting to include any tables. Lovely tables of numbers, still piping hot from the oven.

Can you remember the gist of my last Mackeson post? No. OK, I'll repeat it. The lactose additions don't feature at all in the brewing records. So the OG in the logs doesn't match that found by analysis of the finished beer.

Here's what the Gravity Books, Whitbread and Truman have to say:

I hope you enjoyed that as much as I did. No, more than I did. To be honest, it wasn't the most fascinating five minutes of my life. Not even the most fascinating of the last 10 minutes.
