So the question is about gluten contamination from processing facilities. Difficult to say for sure and the product is not labeled gluten free but I will say it’s unlikely to contain ANY gluten down to the ppm level since the processing facilities for grains are very different than the facilities for sugar cane.

Glucose and sucrose are both naturally occurring sugars from fruits and plants. Sugar and gluten are two totally separate things to begin with. The second half of your statement/question is a probable concern as a lot of food processing plants handle both sugars and grains containing gluten.

Sure they will.

Yes They will still work

Yes capped beer have to be kept at room temp. for 2 weeks to carbonation.

I've never had an issue cold crashing and then bottling with these drops. There's still enough yeast in there to carbonate.

They will work just need more time and probably some higher temps for a bit

It should but will probably take longer. When i bottled regularly i noticed it taking maybe an extra 2-4 weeks for bottles to carb since theres less yeast in cold crashed beer.

One drop into a 12 oz bottle should give an average carbonation (for most ales and lagers) of somewhere between 2.2-2.7 volumes of CO2. If you wanted to calculate it exactly you could weigh the drop to see how much sugar is in one drop then use a Beer Priming Calculator online to calculate how much CO2 that volume of sugar will give you per 12 oz of beer. Cheers!

I would say 2.5 volumes.

About 2.2 volumes

We use 2 drops for 32oz bottle. Recommend for first time use 1 drop for 12oz bottle.

I have used them only with 12 oz bottles and they work great. One drop per 12 oz bottles. One drop would probably work on 15.2 oz. Two drops I think would be too much.

It would be a tad under carbonated but probably ok depending on style.You could always chop a tab up into 4-6 pieces and use those to get you there

Yes.

Depends on the style I suppose but I would say yes it would for all but the most highly carbed styles

Yes absolutely I do so all the time works perfectly.

I would say you will probably get a slightly low carbonation with one tab in a 15-16 oz. bottle. Similar to an English ale carb level. One tab just barely gives an acceptable carbonation level in a 12 oz. where 2 tabs in a 22 oz. seems just about right. It may seem like I'm splitting hairs but that's the experience I've had.

I have used these only for 12 oz bottles and they are a bit light on carbonation. I actually add a bit of additional corn sugar to each bottle now. I have no had issues with over pressure but I think yo are good with your larger bottles if you use 1.5 to 2 per bottle. Just my opinion

I usually fill 6 to 8 Grolsch bail-tops each time I bottle a batch and one carbonation drop in these seems to work just fine. You have to let it sit at least a week to ten days for ale at around 68 degrees otherwise it may seem like the drops aren't enough sugar to feed a decent head. Patience pays!

I haven't tried them with Grolsch but they work fine with full pint bottles.
