I posted this into the wrong section for some unknown reason...

Just thought I'd share a recipe for a Tea Tree (Leptospermum scoparium) Kolsch I brewed recently.

Ausmas Tea Tree Kolsch (23L)

4.5 Kg Weyermann Pilsner malt
250 g Cara-Pils Dextrine
100 g torrefied whean
25 g Weyermann CaraAroma

60 g Hallertau 4% AA (90 minute boil)
100g Tea Tree (Leptospermum scoparium) branch tips (boil 5 minutes)

1/2 tsp Irish moss

1L starter White Labs WLP029 German Ale / Kolsh yeast

Mashed as a double decoction: 50 deg - 66 deg - 73 deg.
Fermented a week at 20 deg. (Fermentation was over in 4 days) in plastic, then 1 week secondary in glass, then 2 weeks in a keg to clarify and carbonate.

Stunned by the flavour, with the tea-tree obvious though not overpowering. It complements the Hallertau hops very well. Colour is yellow-pale gold. The yeast used is a very clean fermenter and the finish is quite malty to balance the aromatic tea tree (probably from the double decoction).

Looking forward to hearing whether others have used tea tree and what results they had. I first came across the concept in New Zealand when I had some Captain Cooker (brewed with Manuka, the same tea tree species), though mine is way paler.
Also looking forward to seeing how the tea tree flavour evolves over time.

Cheers,

MFS.
 
Well it's been 2 weeks in the keg at ~6 degrees and the flavour is fantastic!
I was a bit concerned I'd overdone it but not at all. The tea tree tastes a bit like a funky hop!

What more can I say... I'll be brewing it again!
 
Very interesting!

A old colleague of mine was doing her PhD thesis on the anti-bacterial and anti-fungal action of tea tree. She might be interested in this...

Anyway, I'd love to try something like this. I'm always down for new things :D
