After lacto fermenting some carrots, I decided to use the brine to inoculate some unhopped wort made from spraymalt.
After a few weeks of sitting there I put a small amount of the Wilner Brett strain in the mix.
At my allotment my chamomile and lemon balm was taking over the herb patch, so great bunches were cut, leaves and flowers. I made more wort with spraymalt, and boiled the herbs in for about 5 minutes. I don't know the exact weight of herbs but the impression was about the same ratio of herb to water as I would normally use when boiling spaghetti. Enough water to cover plus a bit of space in the middle...
Medieval precision aside, the wort was allowed to cool and pitched on top of the lacto sour. After 12 hours a some dry Nottingham was sprinkled on top. The gravity was probably about 1.040.
Entirely separately I turbid mashed a 90 percent lager malt 10 percent rolled oats grist to give a 1.035 wort. Hopped with 20 IBU of Fuggles, and inoculated only with bottle dreggs from some saisons including Brett for a few days. Then the St Austell brewery strain was pitched. After a week it was dry hopped with 0.5 g per litre of Fuggles and spent three days on the hops.
The sour was very sour, and the turbid stock ale was slightly smokey. I blended a bit of each using a pipette and the result was much greater than the sum of the parts. After a bit of messing about I decided on 60 - 40 stock to sour. Each was racked in the right proportion to a new bucket. After three days of melding the mix was bottled to 3.0 vols in 750 ml champagne style bottles which were capped.
The finished beer is a good level of sour. The lemon balm gives a tea like flavour, rather than fresh lemon, which gives a more lemon-curdy taste. I think this beer might have been better as not a sour. The herb aromatics would add pungent floral flavour to a hoppy beer. As it is the sourness just cuts through the floral too early. If this was re-brewed, I'd stick to a clean saison yeast and load it up with Sazz. It is hard to tell with so much going on, but I think the turbid mash adds an interesting grainy flavour.
