Definitely! There’s no specific ratio for that, though. It really depends on how big your glass or water bottle is, and how fast you’re drinking it (how long the flavors will have to develop). You may want to use a few more slices than in my recipe’s base ratio, if you’re making individual glasses of water – assuming that you’ll be drinking them fairly soon after you make them. Using extra slices will help the infused flavors to strengthen more quickly. (And remember that you can reuse your slices for a second or even third glassful. See Tip #7 above.)
