I suppose that's the same/similar yeast to Wyeast 3711 or Belle Saison, so the mash temp may be inconsequential, otherwise for a dryer beer, my rest would be much cooler than 68 C - I target 63/64 for mine.

I'd love to hear how it turns out - an all herb beer (at least no hops - other than a sour) isn't something I've been brave enough to do just yet.

The mash temp is deliberately high, because M29 is a very attenuative yeast; typically 80%-90%. (I got 100% with it once when I mashed too low.)

I've made an all-herb, no-hop Gose a couple of times; recipe is here.
It will be really interesting to see if this one goes sour or not. I waffled about kettle-souring it and ended up deciding to start out clean and see where it goes. If the yeast performs as expected, there won't be a lot left for bacteria to work on.

Brew day was a lot longer and more complicated than expected.
First I did a protein rest, which was a novelty for me, and then tried raising the mash temp with a decoction in addition to adding boiling water.
Then I added too much water at mashout and ended up way lower than my target gravity, so I pulled about 1.5 gallons and boiled it down to syrup. That took forever, but the result was a wonderful Maillard syrup that I think will really enhance the malt character.
And the stainless scrubby I had put into the kettle outlet got dislodged, so the pump intake kept getting clogged, and chilling took forever (I use a counterflow chiller).

The aroma coming off the short boil after adding the herbs was wonderful. I hope some of that persists into the finished beer.
