From my experience, Yooper is almost always right. I only say almost because I haven't read every post she has ever put up, but everything I have read has been bang on.
Your OG of 1.081 tells us how sweet this juice was and as such tells us that you are currently looking at about 11% ABV in your cider. Since you have such a high percentage of alcohol in your cider, that means that you should have a lower FG reading when you are done.
The specific gravity of water is 1.000, and the sugars in your cider boost this number up to 1.081. As the sugars ferment you lose the SG boost the sugar gave your cider, and it drops closer to the 1.000 mark. However you are also creating alcohol, which has a much lower SG than water. So with about 11-12% alcohol in your cider, your SG will drop even further.
Now since you have EC1118 yeast in you cider, this means that your yeast has a high alcohol tolerance. You can expect EC1118 to keep going to about 18% ABV if they are provided with enough sugar.
Your cider has about 11% ABV in it and SGs of 1.00 and 1.004, this tells us that you still have fermentable sugars in your cider and not enough alcohol to stop the EC1118 yeast from fermenting your cider further. THIS is why Yooper is right and you should be careful about bottle bombs.
I hope this post helps; I don’t want you to get yourself hurt.
P.S. – It is nice to see another Canadian on here! I hope you keep up the brewing, it is a lot of fun.
