Sugar Conversion Tables, Making Wine from Sugar Cane: Wine Wizard

Sugar solution I am fairly new to home winemaking having only made a few kits and three batches of Muscadine wine. I have been using Daniel Pambianchi’s book Techniques in Home Winemaking as my primary reference and have recently acquired The Winemakers Answer Book. My confusion arises from a disparity in the Brix/SG/PA tables. Techniques in Home Winemaking lists an SG of 1.09 as 21.6 °Brix with a PA of 11.2 while The Winemakers Answer Book lists SG 1.09 as 22 °Brix with a PA of 12.7. Why the large difference?Bob CurrulLake Como, Florida For the Answer Book I referenced the Table 1-2, Appendix 1, from Wine Analysis and Production, Zoecklein et al, 1995 for the Specific Gravity to Brix tables. Note that this conversion is at a specific temperature — 20 °C. Daniel’s table may have been slightly different, or just a choice in how the table calculation he referenced rounded the decimal points. As far as the potential alcohol, I know I’ve answered this before — even “experts” (wine chemists, etc.) will tell you that it’s really hard
