Please don't take this the wrong way, but this seems to fall into the 'too little, too late' category. If you don't have the equipment you think you need and you have no experience making images of your subject, is the day you're going out the right time to be asking such a question?
If you want to make macro images, buy or rent a macro lens. Learn how to use it. You may decide you need a ring flash or other two-head flash unit. You may wish a tripod. If you want to make pictures of a winery, look up wineries on the 'net and study the images. What focal length lens (approximately) was used? Distance to subject? Lighting? Composition? Take your camera out and practice making images with it. Be critical with your images, using the same criteria. If you're not happy with an image, what is it about the image that you don't like? How could you have made it better? Go try that. Look again. If you like an image, why? What is it that works for you?
Making great images is no secret, just a lot of practice, some guidelines and determination.
