Brew King Vintner's Reserve Reisling. Pitched yeast, OG of 84 Ferment temp was a steady 68 deg. F. Exactly one week later, almost to the minute, the gravity was about 30. The instructions said that gravity should be about 10 or less by now. I put the carboy on my workbench and put a space heater underneath and have raised the temp to about 74 F over the last 24 hrs. I get foam that comes and goes. At one moment there's some foam, later the top is covered in foam, then there's no foam. It tastes good, similar to a vodka sour. The must is very opaque.
Can I assume that my lack of attenuation was/is due to the ferment temp of 68 deg? It said I should keep it around 68-75. It's still bubbling away, hopefully still fermenting and not stuck/offgassing. Is it supposed to be very opaque? Instructions say to rack after it reaches 10 or less. Should I rack anyway or leave it until it's more attenuated? It looks like grapefruit juice but tastes pretty darn ok. As this is my first batch I have no benchmarks and need veteran experience.
Thanks,
Kevin
