John Tredgold (JT) is a member of Bread Bakers Guild Team USA 2010 (Baguette and Specialty Breads section). He shared his 85 x 3 formula from the Breads Draft Class at the
Basically, JT’s formula is a story of fermenting, employing three types of pre-ferments: biga, poolish, and levain, and using a specialty flour containing 0.85% ash content (Central Milling’s Organic Artisan Old Country Type 85 Malted Flour ). This is a high extraction flour, about 82 – 85% rate of extraction of wheat berries. It is roughly equivalent to the French T80 flour which normally has ash content ranging from 0.75% to 0.90% according to Prof. Calvel’s The Taste of Bread, page 4.
I recently came across a South Australian organic miller, Four Leaf Milling, which produces an 85% Light Flour . This flour is derived from whole wheat by removing approximately 15% of the bran. I am in the process of finding out more information about it, but in the mean time I thought I would use my French T110 flour to try JT’s formula. The French T110 flour generally has higher ash content (1.00 – 1.20%) and higher rate of extraction (85 – 90%).

I attempted this formula three times. Each time I scaled his formula down to 5% for a

The flavour of this bread is exceptional. As I took my first bite, the rich aroma hit me. As I chewed, the flavour continued to unfold and deepen. All else being equal, I attributed this rich flavour to the favourable climate for making slow rise levain bread. In Australia (or should I say, in Queensland where the winter is mild), the best time for making levain bread has arrived!

I must be a person who is easily moved by people whose passion I can recognize. I see in JT what I have seen in Gerard Rubaud . I may be wrong, but some passionate pursuits are lone business.
