Kolsch (again)

I saved the yeast from my last batch of Kolsch, and given the time of year I though I'd get another one on asap to deal with visitors. This is a beer I don't mind drinking, but not a favourite by any means. All the same, it requires a certain amount of skill to come up with a very pale, clean tasting beer, with no-where to hide in terms of fermentation issues etc.

An early tasting of the previous batch

I decided to change the recipe a little, based on a Jamil recipe from a Kolsch article of his in a 2009 issue of BYO magazine. This is just Pilsner malt and wheat malt in a 95/5 ratio. I had planned to go with Hallertau hops, but my brew shop was all out, so I went with Spalt. This is a hop which many people report as having quite an odd flavour profile. I'm interested to see what it's like in the finished beer.

Mashing was at 65 for 50 mins (recirculated through HEX), then mash out at 75 for 10. I no-chilled this beer. One unusual thing about my brewing setup is that I never measure volumes, just guess based on experience how much water/wort I've got at each point. This has never let me down before, but on this brew I ended up with 22.5L of 1.044 wort instead of 20L of 1.049 (after trub losses). This is actually quite a mess up, and is a bit of a wake up call for me, I need to sort out my volume measurements.

Anyhow, here's the recipe:

4.72KG Joe White Pilsner Malt
0.25KG Joe White Wheat Malt

30g 4.75%AA Spalt hops @50
10g 4.75%AA Spalt hops @10

whirlpooled for 20, then no-chilled.

This will stay in the no-chill cube until the London Pride clone is done fermenting, then I'll pitch some WY2565 slurry to this and ferment at 16 (one degree lower than the last batch). I'll also give it a blast of O2 and try to dry it out a little. The previous batch is not quite dry enough based on early tastings.
