Hi Russ Campbell,
I like your question and before I answer it I want to make sure we are on the same page... When it comes to roasting, brewing and tasting coffee, its all subjective.
I hear and understand your concerns with cafestol. From the research I have done in the past, you can increase your cholesterol levels around 8% if you drink 4 or more cups of paperless filtered coffee a day (8oz cups and I do not know the duration of this study).Espresso, although exracts more cafestol then paper filters, extracts less then boiled mthods. Drinking 1 -2 cups of unfiltered coffee has provided inconclusive results in the increase of cholesterol or increase in heart disease. Another fact in the increase of cholesterol when drinking coffee is that a large percentage of people who drink coffee daily also tend to have other habits such as smoking, drinking, unhealthy diets, etc. Please account for life style choices when researching coffee consumption.
When it comes to which paperfilter brewing methods you should choose, I personally would base my choice off of what kind of extraction/ coffee I was looking for/ wanted to use so I could extract the flavors I was looking for (i.e. more body or less, more acidity or bitterness etc.). With that being said, try using the Hario V60 with a bleached filter (bleach filters impart the least amount of filter flavor). If you use any paperfilter method, I would recommend using bleached filters.
Last but not least, do not push FP, Espresso and your Aeropress aside because of concerns about cholesterol. Each of those methods produce incredible flavors. My only exception would be if you already have bad / high cholesterol or a family history of it.
I hope this help answer your question. If you have any other please do not hesitate to ask.
Thank you,
Howie Schultz
PS. I drink lots of coffee all day long and have a clean bill of health.
