I opened a test bottle of K tonight. It's my first batch of practice homebrew that I enjoyed drinking. It was only bottled last Monday but it's developed a decent carbonation already.

Sadly the same can't be said for the batch of X which still looks to be flat as a pancake. I may re-bottle that batch, or just pour it away. There's a jug of it in the fridge which is doing good service as meat marinades, liquid component of bread, etc. One of those happy symbioses that start occurring when you process things at home.
