Top Sauce versus Casing

[NeverBend]

Thanks - very informative. I didn't know any of that, and thought topping and casing were interchangeable terms. So far straight VAs, VaPers etc. are just too subtle for me, and it's the Oriental/Latakias I'm appreciating most. I'm going to give LA Flake another try soon. In fact, maybe I'll smoke a few VA blends in a row to try to figure them out better.

So is there a difference between the coumarin and tonquin flavors, considering they come from the same bean? And which McConnell blend(s) use it?

I don’t believe that you were alone in thinking that casing and top sauce are interchangeable terms. The difference can be illustrated by burley that readily accepts flavors and is the base for most aromatics and virginia that doesn’t (readily) accept flavors and in consequence is usually top sauced instead.

This is a great explanation of coumarin: Coumarin wiki

I don’t know how tonquin is derived but I assume it to be a different method from coumarin, perhaps not an extract but rather a ground part of the tonka bean made into a solution.

I notice tonquin far more than I notice coumarin or possibly it’s used more liberally. I found that in McConnell and Sobranie mixtures the coumarin enhanced the natural aromas and added a binding faint sweetness that tastes integral to the leaf rather than artificially added. The result is a smooth, rich smoke and I doubt that anyone will duplicate the classic mixtures from these companies without using coumarin. McConnell and Sobranie used the best leaf and knew how to use coumarin as a top sauce to great effect.

I don’t know of any company that still uses coumarin. McConnell used it until they closed in 1989 but I don’t know about Sobranie. McConnell made their own line, Rattray’s, (my brand) Elephant & Castle, Ehrlich’s, Charatan and others. Some of these marques have been made by Kohlhase in Germany since 1989 but without coumarin (evident in the first German tin of Red Rapparee that I tried). Not all McConnell made mixtures used coumarin, but most of the English and Balkans were sauced with it.

Coumarin mixtures seem to age well, at least for a time, but the underlying tobacco may not. Tobacco packed under pressure ages faster than when packed loose. Latakia loses potency quicker than virginia, so very old latakia mixtures packed under pressure, like the 50-gram Sobranie #759 (black) start going downhill (imo) after about 8 years. It’s possible that coumarin actually degrades the tobacco and certainly McConnell and Sobranie didn’t make mixtures in the 1980s with the expectation that they’d be stored for many years.

I smoked hundreds of tins of McConnell (and Sobranie) so if coumarin is dangerous I’d probably have already grown another head.

I think it’s very normal to prefer latakia mixtures in the first years of smoking, it’s a big and direct flavor and they’re generally more forgiving with things like a tight pack than virginia. Flakes are a little more difficult to become comfortable in smoking but it’s nothing more than practice.
