Attempt to sparge with a variety of methods, mainly mixing water and allowing to
settle, then syphoning off excess. Towards the end some kind of sparging was possible.
“Sparged” a total of about 38 litres in two pots. pH of sparge was 4.1, tasted
sour, presumably lactic acid. Added 45 g sodium bicarbonate before boiling to bring pH back
to 5.6.

Never mash with plain wheat flour! This was a disaster.
-
Despite sparge problems, surprisingly strong wort.
