Double Bass Where to get the freshest Carlsson?

I've bought from Gollihur and Lemur. Gollihur seemed to last a while (about a year?) before starting to harden. The Lemur cake was kind of hard when I received it. I don't use it very much as a result. So what's the best place to buy the freshest Carlsson?
 
Have you tried to recondition it? Heating it helps. Also you can place the rosin is a sealed container with a little bowel of isopropyl alcohol. The rosin absorbs vapors from the alcohol.

REF: Double Bass - How to revive old rosin using rubbing alcohol...
Thanks for the link, but I'm asking about who sells the freshest Carlsson.

As a side note, I ruined an old cake of Pops doing the alcohol technique, but I might have used too much alcohol. The link says to use a 50/50 mixture of rubbing alcohol and water, right?

It takes experimentation to fine tune your process.

I have only used heat. Since I grew up in South Texas, there was plenty of that. My guess is exposing the rosin to alcohol vapor for a short period of time and then using a bit of heat would work really well.

I've used the stovetop before (in a double broiler) for trying to rejuvenate rosin, but never had great success. For Carlsson, which comes in a foil tin, would the foil need to be removed before heating? Obviously the answer is yes if using a microwave, so how would you go about microwaving Carlsson? Remove the foil and leave the cake in the plastic cup and microwave away?

Sorry. It's been a long time since I heated rosin. I know it can be done, but don't remember all of the fine details. If I remember correctly, it's a good idea to remove the foil or wax paper cover or it will get encased in the rosin.

However, removing the cover causes another problem in that the rosin tends to stick to the plastic tube. I remember squeezing the plastic tub to break the rosin loose. I don't remember if the rosin was still in its foil or wax paper sleeve.
 
I put mine on a cookie sheet, just as it is. I might roll up the foil casing which is soft and somewhat lead-ish. I put the oven on the lowest setting and heat it up. Then I turn it off and put the rosin on the cookie sheet in the oven. Then I just sort of watch it, opening the door to check its progress. It shines over at first, then actually becomes quite pliable, I might take it out and reshape the sides with my hand and put it back in until it has the shiny appearance I'm looking for and before it gets drippy. Perfection

How often do you find you have to do this?
