Your first concentrate

Concentrates are far stronger than flower, so the right first move is a small amount of something approachable. Play is the everyday house line, with concentrates and rosin carts that keep the dosing clear. A piece about the size of a grain of rice is a lot for a first try. Wait to see how you feel before you add more. If you are new to the equipment, ask the Grand Rapids team about rigs, e-nails and vaporizers before you buy.

What the label tells you

Read three lines: the type, the THC content and the flavor notes. The type says how it was made, solventless or solvent-based. THC content is strength. Flavor notes, often terpenes or a strain name, tell you what to expect when you use it. Flavor is a normal part of the conversation at the counter, so say what you like. Live rosin vs. live resin explains the main split.

RKIVE Reserve in Grand Rapids

RKIVE Reserve is the solventless line, made at Olswell's Adrian lab with ice water and mechanical separation, and no chemical solvents. It is the one to look for when flavor matters most. The RKIVE Reserve page has the brand story, Play covers the everyday line, and the live menu shows what is available at 28th Street today.
