Hi Joshua,

Thanks for the link. Sounds like I did the right thing. Basically I don't waste good beer on large hydrometer samples, so when the wee yeast beasties stopped churning and the head collapsed, I cranked the ambient temperature up to 21C. Let's hope that does the trick

Cheers

Thanks again,
