I'll definately visit next time I come up. It wont be in Jan... but the fresh hop Saison is a brew I never miss out on at Hallertau. So, early Feb - I'm taking a week off to harvest the local fares and maybe even dig out the odd mash tun.
When I have this kind of time up my sleve... I can definately affford the time to visit friends.
For 10L of strike water I add (to the mash): 4.0g CaSO4, 1.7g CaCl, 0.8g MgSO4, 0.7g NaCL, 4.0g CaCO3
For 25L of sparge water I add (to the kettle): 10.1g CaSO4, 4.2g CaCl, 2.0g MgSO4, 1.6g NaCl (no chalk)
These figures were calculated using the Jim's Beerkit water calculator, set to the Bitter profile. As my input water I average the values for Ardmore and Waikato, as that's where Watercare says the East Coast Bays get their water from.
Once I get the output from that calculator I pop it into John Palmer's Residual Alkalinity spreadsheet from How To Brew in order to work out the pH adjustment (which is where the chalk amount comes from). As an input colour I use 7.0 SRM as this seems mid-range for most of the Ordinary bitters I brew.
Since I've been brewing a lot of very similar beers recently I've just been re-using this water profile.
I'm not saying it's perfect, but I get nice clear wort, good efficiency and a nice level of bitterness, so it works for me.

All weighed and ready to crush, a repeat of the last cascade ale recipe, but in with a KG of Global Kolsch (out with a KG of Malturop)
So
67.5% Malturop
25% Global Kolsch
7% Pale Crystal
0.5% Choccy
1.040 and 25IBU Super Alpha / Cascade with uh-oh 5
Looks like the Mild could be pulling up early again too - thick SO4 yeast cake in the bottom of the fermenter like last batch.
I don't think it likes it at 15-16-17, seems to drop out and leave the FG a bit higher - any other SO4 users found this ?
This'll be two malt Tonics in a row by the look of it
