I also do not like my ciders to be dry and I do like carbonation. The problem is that to make a semi-sweet/sweet cider with carbonation you either have to keg the cider or you have to bottle pasteurize it to stop the yeast from continuing to produce CO2.
When you say the 190F method I assume you are referring to the Papers sticky thread technique. I am not trying to discredit this method at all. I do know this method works because I have use it myself. However, this method is not very forgiving if your bottles are either slightly over carved or the bottles have imperfections. Anyone that knows anything about chemistry knows that when a gas is heated the pressure increases. So when a bottle of cider is heated the pressure inside the bottle will increase on top of the already pressurized CO2. Heating the temp at say 190F will increase the pressure more than at say 170F. The other problem is that glass has a hard time going from a very high temp to a cold temp. This in itself can cause bottle bombs.
With that said, I shy away from the Papers method after blowing several bottles... The last time I used this method I slightly over-carbed a batch of cider and blew 12 bottles (4 in the pot on the stove and 8 that had just finished that were sitting on the counter). Between profanities I was screaming and the sound of bottles blowing that resembled gunshots I was very surprised that my neighbors in my apartment didn't call the cops. Not only was it a nightmare to clean up but I wasted 12 bottles of my best brew so far. I am still finding broken glass in very odd places...
I now do a version that is very similar to the Papers technique but with modified temps that I read
here
Also there are people that claim to have used a dishwasher and an oven to pasteurize. I have not tried either of these methods because
1: If you don't know the temp of your dishwasher and how long it maintains that temp then it may not work or it may blow all of your bottles
2: Water works better for keeping temperatures consistent for a more equal heating. Therefore an oven may heat some bottles more or less than other bottles depending on where they are located in the oven.
3. If a bottles blows inside your dishwasher or oven you might ruin it.
Hope this helps!
