I would think you might get away with a straight virginia pipe tobacco for your friend, its not too far removed from cigarette tobacco, like Full Virginia Flake or some other Va flake you may have on hand? Although your friend says he wants nothing to do with pipe tobaccos, you might find he likes these ones, unless you've already tried?

I haven't tried anything on him yet but you could be right, a full Virginia flake might just do it. I don't have any on hand, all I have is tobacco blends, but could remedy that easy enough. Thanks for the suggestion.

"Top flavoring - Some tobacco blends rely on different types of high quality tobaccos to achieve their unique flavor. Other blends use " toppings " or top flavorings which are volatile aromatic flavors applied to the cut tobacco after final drying, usually applied in the cooler and mixed with alcohol as the carrying agent. The alcohol delivers the flavorings into the tobacco and evaporates leaving the flavor behind. The exact formula of these flavorings are closely guarded secrets since they give each brand their own unique flavor."

Don't take it as scientific fact - just food for thought.

If what I've read about tobacco curing and processing is correct, the fundamental difference between "casings" and "toppings"---beside their application at differing stages during processing and the fact that casings are sometimes just sugar, while toppings are usually flavorings---is that casings are water-based, while toppings are alcohol-based. Both are soutions that are sprayed onto the leaves, but the water base of casings evaporates more slowly than the alcohol base of toppings. Thus, casings are absorbed into the leaf, while toppings coat the surface of the leaf.

My latest extractions, filtered to 2.5 microns are definitely cleaner than my previous extractions filtered to 6 microns. If I vape my KGD wicks almost dry, the cotton turns back to nearly white.

John,

I've ordered a pack of the Ahlstrom 2.5 micron filters from Amazon. The text description said a pack of 10, but the title of the page says a pack of 100. I assume they'll send 100 for $12.

I plan to use the 9cm filters in my French Press on held in place by the 5 micron poly felt. I assume I'll need to plunge very slowly (over about two minutes) to allow the filters to maintain their integrity, but I'm looking forward to giving them a try. If the French Press doesn't work, I can always use a Melitta cone and let them gravity filter.

It should be a hundred filters that size for $12. Mine are 15 cm and cost around $17 for 100.

That media flows slowly enough it will definitely add a little press time to your filtering. I have, however, always allowed gravity to do the work so YMMV.

I vaped your Sunset Rum last night and still love it!

Filtering my American Spirit Organic in VG today at the three week mark. Mesh filter over coffee filter. Sitting all day the tobacco is still damp and a good size puddle still in the coffee filter. Maybe the filter is plugged. Probably over half of the liquid has gone into the cup. Very dark extract at this point. I'll give it some more time and then pour what's left in another filter.

Paul, I use a wire mesh strainer to remove bulk tobacco and get it out of the way for filtering. It seems to take about as long for extract to flow through coffee filters as it takes to flow through a lab filter that will remove more particulates so I quit using coffee filters. If a filter clogs you can use another but almost all the liquid will eventually flow through given time.

Morning here and it has all gone through the funnel. I was going to add distilled water to it before this final filter but I forgot. As long as someone has the patience, this method worked fine. Room temp for us is 80-85f this time of year.

The extract is clear but dark, like cola. I'll do a batch of pg and vg for a side by side.

24 hr sale at Pipes and Cigars 20% off coupon code LOYAL

I got the email too, ended up ordering enough to get free shipping on top of that. 20% off "everything" was just too good for me to pass up since I like to sample many different brands. C&D blends are still 25% off through the month of August (discounts don't stack), and Pipes and Cigars will be offering new discounts each day for the rest of the week. It will take me a few months to macerate all the various blends I have coming, but feel the discounts currently available made ordering in advance worthwhile. Several blends were "backordered" but when back in stock P&C will ship them at no extra charge.

Thanks for referencing these qualitative paper filters at such a good price point. I ordered the 2 micron at 5.5cm diameter which perfectly fits in the screw-on base of my filter funnel. $8.41 for a pkg of 100 with free shipping. No cutting, trimming or washing, life is good.

Trying 1% increments up to 20% as soon as I get a boat load of 3ml tester bottles in. From there I'll do a 1% sweep above and below the percentage I find best using 20 3ml tester bottles which will give me a 0.1% resolution for the percentage point I need to use.

For poops and giggles I threw together a 15ml bottle at 1% my NET, 1% my NECoffee, 1% Vanilla Bean Ice Cream TFA, 1% Vanilla Custard, kind of a Wakondaish inspired mixture, 100% PG at 6mg/ml.

Maurice

EDIT: first vape of the 1% juice seems promising in that the NET is still noticeable, mainly the nutty note has remained but the grassy note is no longer there, the final percentage may well be in the low single digits for my tastes. It's very subtle, who knows.

EDIT 2: a quick mix of 1% at 1/3 with the 25% at 2/3 for a total inclusion of 9% brings back the grassy note. I will do my 20 3ml testers in 0.25% increments to 5% rather than anything higher.

Looks like for my particular situation between 1 & 2% is the way to go.

That being said, individual results are bound to vary a great deal with the exact tobacco you use.

I can see including this small quantity in quite a few future mixes. I may actually spring for a cigar or pipe tobacco blend down the road.

Maurice

For gravity filtering, has anyone tried stacking 11>6>2.5 micron cones?

For my next batch of five macerations (all pipe tobacco blends), I intend to try a 90PG/10PGA heat-assisted maceration in a 12-hour water bath, filtered with the French Press method using wire mesh, then a 5-micron poly felt pad backed by a 2.5-micron paper filter. The finer pore lab filters are medium flow rate, so I'll need to depress the plunger very slowly to maintain the integrity of the filter paper. I ordered the lab filters from Amazon last week (listed as in-stock) and am awaiting their arrival before starting the macerations.

I'm not sufficiently well-versed in the physical dynamics of filtering to know if single-pass multi-stage filtering has any benefits. I'd think that three-layer progressive filtration might slow gravity filtering, but would it stop the flow-through entirely? I don't know. So many variables---liquid viscosity, particulate density, composition of the filters, etc.
