Also, how long will last refrigerated?
Do some googling on "sugar crystals in simple syrup" for more complete answers. Short answer -- any sugar will work (personally, I like to make sure it is cane but don't get fancier than that). If it is a true simple syrup (water/sugar and that's it) you will likely have crystalization problems in storage. You should be able to store on the shelf (no need to refrigerate) for several weeks -- certainly, it is used up here before it ever goes bad so I don't know the actual shelf life (your google search may reveal more info on that too). What your search should reveal: the need to add some cream of tartar, honey, or other "non-sugar" items to keep all those sugar molecules properly stirred up and not crystalizing. It should also tell you in what quantity. Good luck!!
Just cane sugar. In some cases you don't want raw or brown sugar that colors the drink.
Sugar and water should keep 'indefinitely' in the 'fridge, and a few months or more.
If it's infused--it really depends on what you infuse it with, herbs not so long...but things like ginger or celery seed you can store for months. Just keep it chilled.
A lot is going to depend on the storage container, if it's exposed to air when you use it and if you put a spoon into it etc, like with a jar.
I use a plan white squeeze bottle from wal-mart (the style you'd see in red or yellow for mustard and ketchup). So, it's easy to dispense a bit for tea or a cocktail and doesn't get exposed to air or spoons etc.
Wow! I'd love to know how you don't have crystalization issues -- I ALWAYS do, which is why I recently researched how to prevent same. 1:1 water/cane sugar, boil at least 10 minutes (low boil). And crystalization occurs within a week, regardless of whether it is in the fridge or on the shelf. I'm totally awed and impressed that you don't have crystalization problems, but it isn't just me, as I discovered when I did the research -- there were some pretty good chemical explanations of the process that causes crystalization. Here's hoping that your syrup stays simple and never crystalizes! :)
I too have never had crystallization issues with simple sugars or infusions. Maybe you have 'starter crystals' on the pan that aren't completely dissolved? Or something in the container you use?
I don't know--that is a puzzler for me. I just boil 1 to 1 water and cane and put in a squeeze bottle. I always do 1:1 as it's easier to control sweetness for drinks.
Umm... wasn't refrigerated... vessel was scrupulously clean (had just been boiled itself) but, I had used some of the syrup (simply pouring out of the vessel). No bar spoons or other utensils inserted. Shouldn't have introduced any impurities, but you never know... interestingly, the articles I read on-line indicated that 2:1 would be more stable than 1:1... didn't check volume, but hey -- next time, right? ;)
Considering that I've always had crystalization problems (usually takes a week or two to truly get going), I'm thinking I'll try one of the on-line suggestions for a touch of honey and see if that makes any difference.
Not sure why there is so much sugar-agnosticism on this thread: any top-tier bartender will tell you that you should be using 'superfine sugar' for your simple syrup:
The finer, the better, the fewer crystallization issues. Yes, you can use Demerara sugar to make syrup, which works great in cocktails, but then you have what's called 'Demerara syrup,' which is a completely different beast from simple syrup,
