I just got my kegging system up, and off topic am LOVING it, but I still wish to bottle a 6-pack now and then. I don't wish to invest in a beer gun or other counterpressure fillers as they are a little pricey for the little I would use them. I remembered someone mentioning a product called Prime Tabs, but when I found their website I saw they were discontinued. Is there any other similar product or will I be spooning in small amounts of sugar?
