Hi GertieG,
it seems to me, that you have actually quite a question here. I've never done goat milk kefir so I can not help there but I've been fermenting cow milk with milk kefir for many years.
First I would say that your temperature is good for kefir, maybe I would suggest bigger oscillation of temperatures so more microbes with different temperature optimums get a chance to live happy life and keep strong in the culture (day/night t difference generally does the trick, I would not recommend one set temperature brewing in this case). Warmer it is, faster is the coagulation and to my knowledge or memory it would be more compact. If you lower your temperature to 45-50°F(7-10°C) for example, than the fermentation will take longer and to my experience it would coagulate in more smooth and less strong matrix. Longer you let the brew ferment, especially at higher t, more compact the coagulate gets and more whey you will have. By the way the taste of the ferment is better if done at lower temperature, at least that is my experience and it applies to nearly anything fermenting as long as it ferments, kimchi, probiotic beverages etc. I'm sure if you search a bit that there are some articles out there which would give you clear answers about the process of coagulation, I'm sure that yogurt coagulation is for sure described in a very detailed way at least for cow milk which should be very similar.
So I hope that at least part of what I've wrote may help you but I'm quite pretty sure that after few weeks of experimenting you will get your answers by yourself.
Sincerely,
František
PS Any special reasons for choosing goat milk by the way? And by the way the culture may be first hibernating when you used it either by lack of food or because being stored in low temperature. If that is the case, it needs some time to wake up and after that it goes at a usual speed.
