So I will say that I broke in my first pipe without a bowl coating a few months ago. It is a Butz Choquin pipe that I won during a charity auction. I loaded the bowl and smoked it. The first time the flavor wasn't great. Well, the first time, it was pretty awful. By the time I finished the third bowl a few weeks later, the pipe was wonderful. Now it is a "go-to" and smokes like a champ.
On the flip side, I have been fortunate enough to purchase some new Neerup pipes. They all have bowl coatings. Every one of them has smoked perfectly and deliciously from the first bowl/light.
No true recommendations here, but perhaps it depends on the seasoning/age of the briar, and the briar itself? I believe it is trial and error.
All that being said, I have never tried the honey approach, but I may consider it if I try to break in a new pipe that is not cooperating.
Fifty years ago, Yello Bole sold new, coated pipes. The advertisements said they were honey coated. I suppose they put some amount of honey in their coating, but also a lot of yellow food coloring, and sugar.
The coating did seem to mitigate the pain of breaking in a new briar, quite well. I coated those with extra honey, from a jar.
The oil cured Lee pipes I’ve grown to love, also go through a break in process. The difference is there’s a sweet taste to them that fades after break in, not a bitter, harsh briar taste.
I’m convinced that breaking in a briar pipe does two separate beneficial things.
Whether or not honey, water, whiskey, or a proprietary coating is used, a carbon cake begins to form in the chamber that protects the bare wood behind it. A coating may help this process begin.
The second part of break in is the extreme heat of combustion cooks and cures out the remaining sap and tannins in the briar. This explains why big, cheap Danish pipes require more smokes to break in. What a coating does for the heat curing part of break in is mask the flavor of new briar.
One thing is sure and certain.
If kept clean of sludge and goo, and rested occasionally so it’s not smoked to death, the more you use a briar pipe the better it gets.
Few other things in life, improve with use.
