My 5 micron filter felt is from a bag filter and cintered on one side which makes it stiff and difffivult to crate a seal. I found filter felt on McMaster carr but don't want to orfer a square yard until I know it makes a difference.
Does anyone know of a place that sells 5 micron felt by the square foot?

McMaster Carr does for $3.04 although the product description doesn't mention it being "sintered".

I decided to try a 5 day room temperature PGA soak using a Gurkha Master Select cigar to see if the PGA would bring out more flavor intensity than my PG maceration of the same cigar. Today marked the fifth day so using a dropper I pulled a 0.5ml sample. The extracted sample is nearly clear with just a slight tan tint. Mixed it with 0.5ml of PG and warmed it in a 15ml stainless steel container to 110f until the PGA evaporated. Mixed @ 25% with a premixed base and loaded it in my Quasar dripper. Quite tasty! Definitely more flavor than my 4 day heat assisted PG maceration. Think I will let it soak one more day and see what transpires.
Two small 4 day PGA macerations, one of Hearth & Home Marquee Magnum O and the other using Daughters & Ryan Ryback, are up Friday. Currently, the Magnum-O is a coffee color while the Ryback is a golden light brown slightly darker than the aforementioned cigar extraction. I also have small batches of Sutliff Voodoo Queen, Dunhill Nightcap, Newminster No. 52 Ultimate English and Cornell & Diehl Bayou Night soaking in PGA until Saturday. Next week I will run 4 day PGA macerations of Cornell & Diehl Big & Burley No. 103, Hearth & Home Signature Louisiana Red, Sherlock Holmes Pipe Club Great Hiatus, Hearth & Home Marquee BlackHouse and Hearth & Home Signature Frenchy's Sunza........ Any that I find "tasty" will be followed up with larger 6 week PG macerations of the same tobacco.
PG and PGA seem to extract different flavor nuances from a given tobacco. PGA macerations seem to provide flavors that are more intense, sharper while PG macerations are earthy and deep. My intent is to mix PGA and PG extracts of the same tobacco together in hopes of obtaining a broad spectrum flavor profile. It will be a lot of fun trying even if it doesn't work out.

I'm thinking in similar directions.
Based solely on the two PGA-based extractions I've done thus far, my experience of the differences between PGA and PG/VG extractions is that the PGA gives a more "open" and "expansive" flavor with greater breadth and subtlety, while PG/VG is deeper, more focused, and somewhat more blunt. I'd use a musical analogy and say that the PGA is better on the treble end of the scale, while PG/VG excels at the bass end.
Our differing descriptions of the flavor profiles aside, I too am curious about the possibility of combining the two types of macerations. One way would be to do two macerations with each tobacco and then make juices using a combination of the two flavoring extracts. This would allow tweaking and fine-tuning the percentages of each extract used to maximize the "full-spectrum" effect. I like that, although I'm not thrilled with the extra work required by two separate extractions.
Another way would be to combine PG and PGA into a single solvent, then use that in the maceration. The only thing this strategy has going for it, however, is convenience---one maceration and one extract. The extra steps of the PGA method would still be necessary---filtering, evaporation, and re-filtering---and might be more complicated with the combined solvents. Plus, the ratio of the two solvents would be pre-determined and fixed in the finished extract. Get the ratio wrong and the game would be blown.
I like the K.I.S.S. rule ("Keep it Simple, Stupid!") and usually try to adhere to it, but I fear I might have to do two macerations each for a couple of Rocky Patel cigars I have that are awaiting extraction. My very first cigar extraction---of a Rocky Patel Vintage 1990 Churchill Maduro this past April---was so spectacularly successful that I purchased a sampler pack of ten more Rocky Patels, all different. During the April maceration, I was worried that I'd ruined the 1990 Churchill extraction by "over-cooking" it for too long (3 days) at too high a temperature (160° F), but---to my great surprise---the extract turned out to be fantastic. The other four cigars I've done are all good, but that Rocky Patel extract is something special.
So, I'm thinking of doing a 3-day high-temp heat-assisted 60PG/40VG maceration and a 5-day room-temperature PGA maceration for both of the next two Rocky Patels, using half a cigar for each of the four macerations.
I have considered mixing PG, VG and PGA to form a blended solvent for use in a long term room temperature maceration. I'm reluctant because I don't know how long PGA can be in contact with the tobacco before adverse effects transpire. I am going to allow one of my current PGA macerations (which ever one I don't particularly like), to continue soaking, long term, taking samples every few days just to see what happens. If long term soaks are a problem where PGA is concerned there is a viable workaround. One could still use such a blended solvent on a sealed maceration at room temperature for a limited period of time. After a predetermined time had elapsed (Let's say 7 days), to un-cover the maceration and gently heat (130f), until the PGA portion of the solvent evaporated, re-seal and continue the room temperature soak with the remaining PG/VG. However, that seems like it would be just as much work/trouble as just processing the PGA and PG/VG macerations separately. Processed separately, a person would then have the option of "custom" mixing their finished extractions, honing the flavor profile to suit their changing taste. What I really need is more experience using PGA for tobacco macerations, more specifically its limits/effects under various conditions and over prolonged periods of time. Discovery can be great fun, more so if the rewards are delicious! Be sure and let us know how those Rocky Patel macerations turn out.
Their minimum order is a aquare yard I'm looking for q place that sells a minimul sqare foot?
Look on the linked page for part number 6376T1, it's on the bottom right side of the linked page. Mouse over and click on the part number and a pop up box will appear. Type 1 for the quantity and then in the bottom left corner of the pop up box click on "12x12" to select that size. It will add it to your cart. I did and it says I'm ready to check out with a single $3.04 12"x12" square of filter felt. Don't know what the shipping would be though.
Regarding PGA extractions, I have done 3 experiments, all involving a solvent of PG and PGA mixed together (2 parts of PG with 1 part of PGA).
For the first one I added tobacco to PG only, and warmed it up to around 50C in the microwave. I let it cool to room temp and added the PGA and let it sit 24 hours (at room temp). Then filtered it, and evaporated all the alcohol with mild heat.
For the second experiment done on two tobaccos, the tobacco was added to the PG/PGA solvent, and heated in a warm water bath in sealed containers for 4 hours at 50C. The extract was filtered and the PGA was then evaporated which took another 2 hours.
The results were all very encouraging to say the least. The main conclusion I can draw from these experiments is that the addition of PGA significantly speeds up the extraction time. The flavor itself, and the strength of flavor, has not suffered in any way as far as I can tell. Its difficult for me to tell as the resultant mixed samples have barely steeped a week, but it is certainly looking very good for such an early stage.

thank you for the part #
McMC can be intimidating as far as product selection sometimes.... ( I have one of their old catalogs real paper book) and its about 3.5" thick great source for prototyping supplies
I finally got around to filtering and reducing the 3 Cherry cold steep PGA extract... had about 4 oz of extract before reduction, after reduction ended up with 30ml. Mixed that into 20ml of VG and its now sitting on the ageing shelf. Its going to be used as a concentrate to mix with more VG and nic base when the time comes.. but as for now, the concentrate is very cherry on the arouma. Did a drop taste test on the thumb. Definately tobacco based and the cherry shines thru quite well. I plan on letting this one age a few more days and then mix up a small bottle for vaping, probably will go 20 nic... it will be interesting to see how it compares to the hot steeped batch of 3 Cherry that I have..
I put 3 cold extracts in tonight, 2 parts PG to 1 part PGA, approx 22-28ml total with approx 4gm tobacco in each glass jar (each glass jar is 30ml capacity). I'm thinking of letting them go for 3 days and filter, then evaporate the PGA. There is color in the mix within an hour or two, which does not happen with straight PG as solvent. The tobaccos are Peter Stokkebye Luxury Bullseye Flake, Dunhill Nightcap, and SPC Plum Pudding. These are the first baccos I have bought from the USA, an ounce each, so there is plenty of baccy left of each type to try with other variations.
I found the source of the fiberous material in the extract from a previous batch.... the filters I used had a wad of finely shreaded paper stuck to the "outside" of the filter. Obviously I didnt notice it when I used it and it got transferred into the extract... I refiltered the extract and had a bit more show up but on the proper side of the filter
I will be checking my filters from here on out for "stuff"
and BTW it was the Merlita conical type... I usually use the pleated bowl shaped ones....

Wow! This new Aeropress I got works great. I was worried it wouldn't travel far enough to press out all the concentrate but it did a great job. I hand squeezed the tobacco afterwards and only got about another ml from the tobacco. Nice investment of $20.
There's more than one kind? I just got a simple plastic one for $20 on Amazon. Just the press, a stirrer, a ladle and the filters.
